Title: Fidding a 18" x 4.5" Rear Moto Wheel Widda Car Tior
Post by: cat0020 on March 15, 2014, 09:31:16 AM
This is probably going to open a big debate.

I've ridden a car tire mounted on the rear wheel of a Suzuki Burgman 650 for over 14k miles without troubles.
(http://i741.photobucket.com/albums/xx55/tcphoto2010/04%20Burgman%20650/Burgman%20stuff/IMG_3972.jpg)

Now I want to put a car tire on a K75S, since most if not all of my riding will be on highways cruising at speed. 

Any K-bike owners ever tried to put a car tire on the rear wheel?

Which make/model car tire have you used?

Any pictures of your car tire mounted?

Well, you are probably right about opening up for an interesting debate.......Liability and Litigation are the 1st 2 things that come to my mind when you start thinking of a modification like this.
Not unlike mcycle dealers that won't patch a bike tire because they don't want the liability if it fails at speed and causes a crash.

Not long ago, no one would consider earth is round.. or that planes can fly.. plenty of car tires have been mounted on motorized 2-wheel vehicles and millions of miles have been ridden on them. No indication that incidents are more likely riding with car tires mounted on the rear wheel.
As someone who has experience riding with a car tire mounted on the rear wheel, I can say that it is safer in most applications when operator knows how to ride, just as any tire, moto specific or not. Just as any new tire mounted on a vehicle, moto or car specific, learning curve of vehicle handling is to be expected.

IMO, liability is for those who depend on manufactures rather than riding skills.

If anyone is interested in my experience of riding with a car tire mounted on the rear wheel, I'm happy to share.
But to debate about this topic without actual experience is like telling someone the riding a motorcycle is dangerous shouldn't be attempted while never ridden a bike themselves.

Really? What information do you have that shows that a car tire on a motorcycle is safer than a motorcycle tire on a motorcycle?

Do the insurance companies have access to your data and experience?

I've not been to a "major" bike rally like Datona Beach or Sturgis, but the only 'car tire' installations on mcycles I've seen have been on trykes, where you won't have the 'leaning' effect on the tire edges.
Short of a custom built bike that may have a super wide rear to fit a car tire, but still a bike you probably won't see in the highway unless it's on a trailer........

14k miles ridden on car tire mounted on a Burgman 650 myself, 45% 2-up riding, never an issue, not even a flat.. that enough info for me to believe it personally... until you do it yourself.. I can not change your mind otherwise. 

Plenty of videos on Youtube with car tires mounted on Goldwings, Triumph Tiger, Rocket IIIs, leaned at steep angles in corners, just a search away.

Insurance company only care if the bills get paid on time.

this came up once on BMWMOA's forum.  First reaction from most people is same as screen doors on a submarine.  But the people who have done it get impressive mileage and not all the bad dynamics you'd expect.  One downside is rear wheel bearing wear on Wings, if I remember correctly.  Sidecars it's a given they work better.  Since most of us, (well, not us but the Wing and noise and chrome crowd) never push our tires past 6/10th having optimized rubber does not matter so much.

I'd be interested to know if there's a car tire that would fit a K75 for sidecar purposes. I had heard that there was one that fit but it was no longer in producton. This was back in 2009. If there's one now I'd sure like to know about it. It's depressing to buy a moto tire for big $$ and have it wear flat after a few thousand miles.

Hadn't seen the videos before(thanks:enjoyed watching them) but first bikes I owned in the 60's had Avon SM rear tires with profile very similar to car tires and no handling issues.Guess finding right car tire for grip etc. might be a matter of luck!

Title: Re: Going "Darkside"..
Post by: wmax351 on March 15, 2014, 06:32:12 PM
You definitely lose some handling, but I don't think the car tire is too big a deal. Might be better for crappy weather/road surfaces. I'd mount one if I was planning on going to Alaska.

How many motorcycle fatalities involving car tire usage do you know of? or does anyone know of?
Please provide some evidence or actual stats that got published.

OTOH, I'm sure most of us know of plenty motorcycle fatalities that use moto specific tires.

Post by: mjydrafter on March 16, 2014, 03:52:07 PM
Have you found a tire that will work?  The k75 has some narrow rims.  So you would be looking at a really narrow tall car tire with an 18" rim.  They may be out there but I have a feeling they will be big $.

Then I think clearance will be the next big hurdle, I haven't really looked but I don't think there is a ton of extra room.

Probably I can fit a 145/60-17 car tire onto the OEM K75 rear wheel without clearance issues.. problem is finding one in that size.

The "LIABILITY" is in the "RECOMMENDATION".
If I "RECOMMEND" you try/use a product for something that it is not designed for and you are injured or killed.
I could be "LIABLE" for the damages in a Court Of Law.

As for using a Car tire on a Bike that is something you should research very well before you try it out.
Scooters, Sport, Sport Touring, Cruisers, & Touring bikes all handle differently and what works on one may not work as well on the other.
For my 88 K100LT I would not use a car tire because of the way I ride.

Good Luck....

Please do whatever YOU belive to be in your best interest.
But, by you posting here asking for recommendations and/or approval puts respondents
in a position of being liable if you are injured or killed. 

Again, please do whatever you feel is in your best interest. I wish you all the best

Well you are overlooking something here that's very important. With a side hack the back wheel being offset to clear the swing arm is not going to present as much of a handing problem as it being offset on two wheel machine that needs to lean to turn. The handling would be spooky I'd bet.

One of those pictures had a car wheel adapted to fit the BMW. There used to be a guy in PA that did 15 inch car wheel modifications $$$ for sidecar use.

  The tire size you mentioned, for the OEM rim with a 60 series profile will change your gearing for higher rev's on highway.

Another alternative to a long lasting tire on your K75S would be to put a Metzeler ME 88 Marathon in the 140/80 -17 size which should give you a long lasting tire. I have put a couple thousand miles on one currently and still no detectable wear.

I have also used Dunlop's economy D404 and get 10-12k out of those.

If you find a car tire that fits an OEM rim let us know.

Well, where did you read that I plan to use a car wheel for my application?

I know the front/rear wheel off-set when a spacer is mounted on a car tire may present a problem, but most car wheels are built with an off-set that can also easily compensate for the spacer needed for the application.

Handling difference of riding a car tire mounted on the rear wheel feels no more different than riding with rear luggage on/off to me.
Any change on a moto can affect handling, safety just depend on how well a rider can cope with the change, however spooky it may be.

Post by: subforry on March 17, 2014, 12:59:06 PM
Interesting, never heard of using a car tire before.  One thing that comes to mind right away is that when the car tire is forced to compress the side wall and bend the tread when cornering and will generate quite a lot of heat.
From the video it looks like the rear tire diameter doesn't decrease as much as a round profile m/c tire.  This means the m/c wont slow down when turned, which will be kind of odd.  Also the contact patch of rear wheel will have a smaller radius than the front, don't know what that will do.
I think the real problem is finding a high performance, high temp rated tire that is small enough in rim and profile.
Title: Re: Going "Darkside"..
Post by: cat0020 on March 17, 2014, 04:04:31 PM
Keep in mind that car tires are designed for vehicle weight 3 to 4 times of a motorcycle; withstand forces generated by vehicle 3 to 4 times as heavy as a motorcycle.
Whatever handling difference by using a car tire vs a moto specific tire is just something to learn for the operator, as for any new tires mounted on a vehicle.

Then Do It!
Start a project post, document your work and post your findings.

I have done some surfing and see that almost all the MC to Car tire/tyre conversions were done to mostly to heavy cruisers and the large touring bikes. There was a few videos of a Triumph Rocket 3 and a FJR 1300 that did the swap over but none using a BMW K bike (other that the ones who added a side car) Oh and a few Scooter videos.

Just remember to document, document, and oh yes, DOCUMENT your work. The Devil is really in the details.....

Good Luck and looking forward to your results.

Yes, I do plan to do it, not just as a project but to find an alternative to expensive moto-specific tires.
The performance parameters I am looking to get out of a car tire is not the same as a moto-specific tire,

Just look at the video I included in my previous post; there is a Suzuki VStrom using car tire on its rear wheel, those bikes are top heavy and yet pretty well known for carving in capable riders' hands.

I'm not doing this to pass DOT inspection, I'm doing this on my K75S that is over 20 year old and just for the bike to suit my purpose.

Profit from selling moto-specific tires is one big reason,

Liability is because people don't take responsibility for their own actions, always look for someone else to blame when bad things happen.
Most if not all casualty on motorcycle occur when using moto-specific tire, and you expect people to be patient enough to learn and master handling difference using car tire?

Having ridden 14k miles on a car tire mounted on the rear wheel, I know a few thing about how a car tire handles on a 2-wheel vehicle, and that Russian Roulette has not gone off on me yet. Naysayers can do all the talking, but without practical experience in this topic, they can only be words based on zero experience.

Yeah, I have to say, BT43's are 100 bucks a pop, and can last 10k miles. I think the only situation I would consider it is where I need more than 10k out of a tire, because I wouldn't want to carry a new one.
Title: Re: Going "Darkside"..
Post by: Opus on March 22, 2014, 07:50:18 AM
After checking out some of the videos and other sources I can understand why some riders choose to go with a car tire over a MC tire.
A lot depends on your riding style and locations where you ride the most I think.  Just running in the city or open highways with little or no twisties a car tire would work as good or better than a MC tire due to the fact you are riding in a more upright position almost all the time.
This style of riding uses mostly the center of the tire for traction. The contact patch on a car tire would be greater than a MC tire making it a better tire for commuting and long distance (Non-Sport) touring. Including longer tire life, wet surface handling, improved riding comfort, and lower replacement costs makes a car tire look very good. As stated before in a earlier post, car tires would most likely work well on Heavy Cruisers, Choppers, and Larger Touring bikes.

Although there are videos of car tires used on Sport & Sport Touring bikes I would not use one unless my riding style was the same as I stated above.

That being said, I would not use a car tire on my K100LT.
I'm not saying it would not work, it's just that it does not work for my riding style.

Done properly, a single $65-$90 car tire can easily last 20 to 30k miles on a 2-wheel vehicle; in comparison $90-$140 or more moto-specific tire that last 10k mi. or less.

Car tires are designed to support vehicle weight 3-4 times of a motorcycle, to handle stress/forces from a vehicle 3-4 time the weight of a motorcycle. Yes, handling will be different, but that goes for any new tire mounted on a bike; it takes practice to master the handling of any new tire.

We each choose how we ride and what risk we are willing to take. Just because you are not willing to take the risk, or can't think of why anyone would want to take the risk; doesn't mean those who do deserve criticism for something you don't understand.

Hmmm, a curious reply? I'm pretty sure that I didn't criticise you, or anybody else in my post - I simply said that I couldn't understand why anyone would want to do this and you've not explained it in your reply? Seems to me, by your calculations that you'll save about $150 in 25k miles. I also doubt an insurer would pay out once they discovered you were running a car tyre on a bike - could be wrong though but it might be an idea to check with them.

Did I miss the REASON for a car tior? 

On a sidecar rig it makes sense as long as you are not planing on flying the chair regularly.  I have a friend who has some flavor of a Honda sidecar rig (longitudinal V4 or 6?) that has car t i r e s front rear and on chair and it seems to be the right answer.

The handling problems and t i r e construction would concern me.

Going into ANY turn above walking speed you need to lean the bike.  When the bike leans over with a squared off cross section t i r e  (Even a well worn t i r e  will do the following...) the bike will be levered UP from it's normal position as you lean over.  This not only raises your CG as that happens but it also steepens the steering rake as the back end comes up (Unless the front t i r e had the exact same profile which is unlikely).

That alone would make the rear feel a little squirrelly (at least to me... the last Dunlop (I forget the type) I had on the rear of my LT, I could FEEL it lifting up on the edge that had developed due to a series of long slab trips.

Add to that the fact that the t i r e manufacturer never intended that tior to run on the corner of the tread pattern ever makes me consider this a no go in a motorcycle situation.

My mate had a Honda Shadow 750 bobber, matt black, red wheels, ape hangers. He wanted the wide wheel look and spent hours in the machine shop. He fitted a Cossack rear wheel and car tyre in the front forks and a wide car tyre on the Honda rear rim. "  that looks the dogs boll**ks what's it ride like?" I asked. He took a long, deep draw on his cigarette and for a moment savoured the smoke in his lungs, inspecting the tip of his cigarette he exhaled and with one eye closed answered "It's sh*t".  :falldown:

A motorcycle tyre costs £100  its designed for quick heat build up to increase grip and to withstand rapid acceleration. On most the centre compound is harder for highway use and softer on the side walls for high speed turns. Unless you buy a sports compound tyre for massive grip but poor longevity ( speed is expensive). The internal design and construction differs from your average run of the mill car tyre, the profile is designed to offer greater lean grip through fast corners or emergency get me out of the way of that car, truck, Moose.

The average car tyre costs £50, its design mostly to work with three others taking mom and the kids to school. When Mrs Beckham is taking the kids to school in her 190 mph Lambo you can bet Dave is sticking some serious rubber on it and not messing with the rapid fit discount blokes.
Yeah a car tyre will do 100 mph down the motorway if you have a blow out you still have three to play with and its down the pub that night telling big Steve all about your crap day. On a bike you lose one and its good night Vienna. Do me a favour mate save your dosh and buy a hard compound bike tyre for highway use, save the fat arse look for the Hardly Riders MC.

90% or motorcycle riders don't push their tires to 50% or their capabilities.  95% of the chrome and noise crowd it's all about image.  85% don't put 3000 miles a year on their bike. Chances are if you go darkside and crash you would have crashed with bike tires.  Show me a raked out hardtail with apehangers, straight pipes,  chrome skulls and a car tire and I'll lay odds the car tire is the least dangerous mod.  And I made up 80% of these stats.

Yeah --I've been waiting for that info too. I looked into a k75 car tire for my hack back in 2007 and couldn't find one. When you can get a Shinko for $65 shipped it's not worth the hassle of doing the smart car wheel mod for the hack and that mod has been documented on ADV Rider theres no point replicating it here. If I get 6000mi on a Shinko rear then I can go 24k mi for $270 which with time, labor and parts is much less than I'd spend on the smart car mod so that discussion really doesn't belong in the wrenching section because nobody here is wrenching on it.

No car tire available, ergo no real point in this thread...except for the pointless hypothetical 'dark side' debate which really doesn't belong in the wrenching section because its not possible to wrench on it without a tire that fits.

So -- identify the tire in a new thread and let this thread die since its dead in the water anyway.

If you can fit a car tire onto that wheel, probably won't need replacement for 30-40k miles.. just handles a little different.

It does not affect handling...just bugs some people. I would say 1/4 to 1/2 inch Just try it..you won't be sorry.

 Not sure why my original post to this reply was moved from thread, but I'd imagine because I mentioned usage of car tire. If that "bugs" people, that's the purpose of these public forum discussions; to have intelligent dislogues.

Honestly, the difference between moto-specific tire vs car tire mounted on the rear wheel of a motorcycle is the affected handling, but the benefit of much longer tire tread life, smoother, better traction at majority of operation and lower overall cost.

I endorse the usage of car tire because I have used it without problems; if that "bugs" some people, that's no reason for my practical experience to be removed from the rest. To move my posts or thread on the topic because the content is not a widely supported doesn't make my experience less valid; only make those who shun on the idea of trying something different display their lack of vision in motorcycling adventure. There are always risks involved in most if not everything we do, lack of data does not indicate more risk.

Dude, your thread was removed because you talk about something without providing any helpful information. If you actually know where to get a car tire that fits the rim, know the model number, manufacturer and distributor, then that info would be welcome here. But if you're going to just do your usual car tire rant even though you haven't actually researched whether a car tire is actually available in this real universe instead of your alternate universe where car tires for K bikes grow from the ground like weeds, then do everyone and yourself a favor and leave it out.

I appreciate the ADV Rider link to the Smartcar wheel mod. But aside from that, your posts are about as helpful as when someone asks for details about a technical issue and you respond repeatedly with "Hey -- you need to fix that!" That's troll-talk, not moto info.

So either become knowledgable about the topic you're so passionate about, give us info we can use and stop wasting everyone's time with hypotheticals or STFU.

Isn't one of the function of these forums to consolidate information and come up with possible solutions together?
Why is solely my responsibility to come up with helpful information?
I provided examples of car tire usage on motos, I provided my own experience in using car tire on moto, I posed questions and hoped for someone to help from the collective of this forum , but instead received replies that are non-contributing and eventually get my thread and posts moved to ignored area of forum.
Does that seem accurate of what actually happened?

BTW, my experience and knowledge with car tire usage on 2-wheel vehicle is not hypothetical, I share my experience so that this community can expand our views beyond the boundary of what OEM designate, utilize materials as something finite and should be maximized for efficiency and value. Not all of us ride to the tire's capability to the max, heck probably not even 50% of the tire's capability through its lifetime; so why not explore other possibilities, together?

Telling another forum member to "STFU", is that endorsed by the forum moderator?
And what have you contributed to this particular thread anyway?

Why is solely my responsibility to come up with helpful information?


Because you're the one who is passionate about this topic, enough to keep bringing it up. That's fine...but if you want to be the main proponent of an issue, then you should also know something about it.

Go reread your thread, it was moved, not removed. I looked for a K75 car tire yesterday. I didn't find one.  I did due diligence, which is more than you've done. So either find the freakin' tire or accept that there is no freakin' tire and stop wasting everyone's time advocating for something on principle for which there is no practical solution.

If you want to do the smart car mod, then do it and post your detailed experience here. Otherwise, we've already got the link and don't need it again.

You're not getting it -- we are all waiting for you to come through here. You grabbed the big bat and stepped up to the plate, now it's up to you to hit the freakin' ball. But please...stop taking practice swings. You're like Nomar Garciappara who never stops adjusting his damned gloves....

I'm saying exactly was said to you at the beginning of your original thread. You didn't get it then...maybe you'll get it now. It's your baby so stop talking and start walking.

Nice comment from article above:

Donald Smith on June 11th, 2012 10:40 pm

(Although it has spread to other makes and models, this movement appears to have originated among a number of luxury-touring motorcycle riders)
Sorry Eric, but you are wrong about where this all started. While I donít endorse the practice I do know itís been going on since at least the 50′s, (probably earlier) with Bobbers & Choppers. Speeds in rural areas averaged more towards the 45 mph range due to road conditions, and the bikes involved. A 45 ci Harley wasnít very fast, and 50 miles was a hard days riding here in West Virginia. My Dad didnít use car tires (He was too fast to trust them), but a multitude of his ridding buddies did. In the 60′s I had a bike with a 15″ rear wheel, and tried it too. Seemed to do OK to me at the time, but most of my riding was on gravel, and woodland trails. A skinny V W mud & snow tire, and I never got stuck in the mud.
That was then. Now most bikes have no trouble doing the ton, and beyond. Even my old 650 Yamaha will do 110. Car tires? not anymore, but there was a time back in the good old days when motorcycling was fun & inexpensive.

As usual, when a Darksider gets called on their incessant raging, they start insulting people. If you were smart, you would not have this battle here, you would just tell people what forum to go to if they are interested in learning about it. Let a forum of "experts" (which is a nice sarcastic euphemism for saying "people that don't understand engineering or physics") help convince and enlighten. But instead you are dead set on changing everyone's mind here all by your little lonesome ... and are woefully under prepared to do so.

Closed minded people? Gang up and ostracize?  So why is it that you can voice your point of view but others are not allowed to voice theirs? You think it is everyone else that doesn't get it ... apparently that includes professionals in the industry as well.  The man just wants you to spend more money so he under engineers motorcycle tires. Yeah, nothing like subjecting themselves to the liabilities involved there.  Maybe it is that people here are just tired of the car tire zealots that clearly have no clue about tire design, engineering, and physics giving anecdotal evidence instead or hard facts and empirical evidence? There are plenty of documents, white papers and articles with interviews of actual tire design engineers explaining why it is not a bright move, looking for you guys to produce the same type of evidence from similar credible sources. But present it like a sane person would, not some religious zealot that repeats himself and says "even though the laws of physics say other wise, I am right".  We don't want to hear about your sisters boyfriends uncle that has used car tires on his hog since he got back from the war. Produce proof, facts and evidence.  You can't, so you don't.  Instead you just yell louder about how your buddy Bubba on forum XYZ does it all the time and then tell people that "don't understand" they are closed minded.  They do understand and can point at facts to back it up.  It is you that doesn't understand - not only about the issue at hand, but how to communicate your position with intelligence.

People do not attack your use of a car tire until YOU bring it up and preach it adnauseum and try and shove it down their throats.  Run a car tire, take what ever risk you want, think you are smarter than in entire industry of highly educated engineers.  The bottom line is, no matter how smart you think you are, if you cannot read the evidence, documentation and understand the physics of why what you do puts you at higher risk, it is you who doesn't get it.  As I said before, because you can does not mean you should.  Putting a glazed donut on your bike as a tire is a "possibility", doesn't mean you should do it.

I reckon a car tyre is more than strong enough to cope with the forces generated by a bike, as stated earlier, a car puts much more load on the sidewalls of its tyres than a bike ever could  :2thumbup:
BUT...what happens when it rains, or you come across a  stream of water midway round a bend? Car tyres work in the wet by forcing water out from underneath and through the tread...not going to happen if only the outside of the tyre is touching the ground!
Might not be an issue in some places of course, but it certainly is in England!  :hehehe

Agreed, plus I know how the handling on my bike goes off when the rear has started to square off so I cannot see how a car tyre could cope over here either. Its probably illegal as well so your bike wouldn't pass the annual MOT inspection. Not for me.

Re your comments in the other tyre thread, the first thing it says on the FJR thread is...

RUNNING A CAR TIRE ON YOUR MOTORCYCLE CAN HAVE INSURANCE REPERCUSSIONS. Claims in tire related accidents have been both denied and accepted.

Good luck with your claim!

Don't need luck with my claims, I've had them gone through multiple times.. regardless of what tior I ride.
Not sure what type of people trust luck for insurance claims, but if you're at fault; you should be responsible for you actions.
If you're not at fault, then you should be covered, does that make sense?

I'm not interested in debating you, I have MUCH more useful and constructive things to do with my time.

I am curious about something, though:
What has been your career choices, your life experiences, and for how long that you have become
"The All Knowing Oz" ?? and know much, much more than us little people.

How many degrees, and in what field(s), do you hold......?

How long have you been riding........and on what ??

Is all this pertinent and valuable background verifiable  ??

As I said......I'm just curious and wish to be enlightened before I kneel in shame to kiss the Pope's ring

You first post in the Darkside thread inquired if any of us have have run a car tior on a K75......
and that you have done so with a lot of miles on a scooter.....
I don't see (I don't feel like going back through 5 pages to verify) where anyone has done that
very same thing of which you inquired.

My last question(s) were just an attempt by a reasonable person to determine your background
and expertise so it may, possibly, reduce all the ridicule and ire you seem to be generating in
this thread.
I'm sure the rest of us would like to know as well so we may all stand in line and apologize to you
if it truly turns out that you are better than all of us......

You are the troll that can't debate according to topic of thread and demand for personal info when you don't even deserve to know.

If you want to know the personal stuff about me, start showing some respect as a normal person, disclose your own personal info/qualifications to support your point of view in the topic, and maybe ask politely as a normal person would.

Would you answer personal questions if I insult you with personalized meme? seems to me you're an idiot for even asking for personal info simply because you can't debate on topic.

Try to be polite now? too late.  Remove your insulting meme and apologize, then maybe I will consider anything other than a troll of you.

Similarly that you will not go back 5 pages, I will not re-read about your personal or professional qualifications.

I mounted and rode a car tior on my Burgman 650 for over 14k miles.

How many application of car tior on 2-wheel vehicles do you have? zero?
Without applicable experience, all you can talk about is theory.. and all you have is your qualification, which do not apply in real life riding.   

look... stop the fussing... answer my question...

i needs car tiors for both my wheels... still have not found them... i needs them by thursday...

so... whats you gotts there cat0020 that fits my wheels...

j o

Do your own research. I've never mounted car tiors on both front and rear wheel of a motorized 2-wheel vehicle, and I would not do it myself.

I only mount car tior on the rear wheel, since they wear quicker than front tior and more expensive to replace. AFAIK, people who ride with car tiors only mount on the rear wheel.

You want car tiors on both wheels, find them yourself, mount them and post your results.

Johnny,   I can't find any car tiors that will fit either a 3"or 4.5" rim that aren't those funky space saver spares with a couple hundred mile life. .  Little research found that you need to modify the FD,monolever and exhaust to fit a car rim .  Figuring for all the chitt needed to make the changeover,  buy a new straight rim a decent tior, and the assorted Rube Goldberg engineering, it'll cost somewhere in the $1500+ neighborhood.  I can buy a lot of ME88's or ME880's for that money and get 10 - 12K outta them.

Ever been in the mountains with a worn out, squared off tire?   Not fun.  On the other hand a car tire might be okay for stylin' around town, but then, those guys don't do 30k in a life time.

This thread is about options for putting a car tire on a bike rim, not about whether it should be done.

There is also an option for putting a bicycle tire on your Brick, or perhaps a swimming inner tube, or  a wooden cart tire  -- further options welcome!  icon_cheers

I would think a car tire would merit a car rim. I dunno, are the sealing lips different from bike to car rims?

Yes, the sealing requirement is different.  The rim and bead profiles are different to handle the different force vectors working on the wheel and tire.

A car tire is designed to operate within a couple degrees of vertical, whereas a moto tire needs to be able to operate at angles as great as 60 degrees from vertical.  Because of that, traction is engineered into the profile over a much greater area of the cross section of the tire.

Car tires are engineered to provide traction over a large flat contact patch, moto tires are designed to provide traction over a much smaller contact patch that varies widely in position around the cross section.  They are also required to handle larger side loads relative to the size of the contact patch.  Because of those requirements, the rubber compounds used are softer and necessarily wear faster.

The problem with a car tire is that as the bike is leaned into a turn and rolls onto the square corner of the tire, it is losing contact area, and what contact is made is through a harder less tractable rubber compound.  Not a good situation considering that as that is happening, the side loading on the tire is increasing as well, increasing the risk of a low side.  All it takes is one such accidental drop to wipe out any possible savings you might achieve using car tires on your bike.

It seemed to me that this thread went off the rails about 8 pages ago. . .

Today was more of a "go ice fishing" day as opposed to doing anything worthwhile.

https://ridermagazine.com/2016/05/20/tales-from-the-dark-side-putting-car-tires-on-motorcycles/

Here is a good resource, with lots of pictures and some nice graphs. It's a reasonable place to spend a little time.

Unless I was intending on driving my motorcycle in a straight line at a slow speed 100% of the time, the $ savings is not worth it to me.

You may observe that there are eight pages of posts on the possiblity of putting car tires on motorcycles, mostly recommending that it's not advisable.

If you happen to be looking for validation of the idea, it doesn't seem that this is where you will get that. But in the letters responding to the original author of the article I referenced above, there are lots of people who swear by it, so everyone has their own idea which is a good thing.

Finally, in answer to your point, internet forums are not widely known as a useful way to spend one's time. Heck, without this forum I still wouldn't know I needed to replace my driveshaft and would be blithely motoring along! (Until, that is, I wasn't).

The incidence of hijacking in this thread has increased alarmingly. I suggest all off-topic posters consider the suffering caused by their behavior and spank themselves into a state of contrition by whichever means can be safely deployed during this contagion then return with more advice.

Stay on-topic.  Another of display of off-topic defiance will result in you clicking here to get on the grid (http://www.motobrick.com/index.php/topic,550.0.html) before you are banned for life.

Hey Indiana k I'm super glad you came back; I was concerned that you might have left this thread permanently. I really did not mean to be offensive.

Have you been able to locate any car tires that would fit the rear wheel (and clear the swingarm) on a k75?

I looked at a bunch of tire sites and there do not appear to be a bunch of 4.5 inch wide, 18 inch diameter tires at all. Or anyone else?
