I noticed today that the front tire (metzler lasertec) on my 1991 K100RS was severely worn down, while other parts of the tire had not been nearly worn down at all. You can see in the picture attached that it has worn all the way down to the threads of the tire underneath the rubber. This wear pattern is ever 3-4 inches in intervals all the way around the tire. Tires probably don't have any more than 4k - 5k miles on them, bought them last year.
Before I go buying a new tire, I want to make sure the bike doesn't chew up another one.
Things I'm thinking could have been the cause;
- Low tire pressure for too long
- Uneven forks
- Wheel poorly balanced
- Bad front wheel bearings
Anyone else here have experience with such aggressive wear on a relatively new front tire?
