Then Do It!
Start a project post, document your work and post your findings.
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,
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 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.
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.
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.
Maybe there's a reason the OEMs DO NOT put car tires on their motos....
Profit from selling moto-specific tires is one big reason,
Different sidewall construction and cornering ability comes to mind, not to mention HUGE liability issues from almost everywhere imaginable.
IMHO you are playing Russian Roulette with (at least) TWO rounds in the cylinder
Just because you can do it doesn't make it right.....
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.
