how often do u need to chain tires on a zx10r motorcycle?
There is no set standard for how ofter you need to CHANGE tires (not chain). A tire is worn out when the tread depth is at 2/32 of an incheither buy a tread depth guage for about $10 at any auto parts storeor the old fashioned way is to check it using a penny.take a penny, insert the top of Licoln's head into the tread, if you can see ALL of Lincoln's head shows, your depth is too low and the tire needs replaced, if the tip of his head is in the tread, is getting low and should be replaced soon. The only other reasons to replace a tire are dry-rotting, nail/screw holes, damage to sidewalls, or any other type of visible physical damage. The mileage you get from your tires depends on your riding style and habits and the rubber compound. Softer compounds give better traction, but less mileage, opposite, harder compunds give slightly less traction, but higher mileage.
Ridden gently with proper air pressure and with sport-touring tires on the bike (vs sport tires) you might get 5000 or a bit better out of a rear and 8000 out of a front. If you ride it like you stole it you are going to reduce your mileage greatly on those tires. It all depends on your tire pressures (for mileage try 38 front and 40 rear), your driving habits, road conditions, type of tire.
Depends on: [1] how soft is the tire to start with; [2] how much heavy braking or accelerating you do; [3] how smoothly do you ride; [4] are you on the street or the track. The range would be between next-to-no-miles, and 10,000 miles or more.
