Do not allow the tires to wear smooth before replacing them. MICHELIN® motorcycle tires have wear indicators; smooth sections appear in the tread grooves, across the tread, when the remaining tread depth is 1/32 inch (.8mm). Tread wear indicators identify when the tire needs replacing. Note: The federal regulation is 1/32 inch. However, some states have a 2/32-inch requirement for motorcycle tires. Check the condition of the tires regularly and replace them when necessary. A tire’s tread life is dependent on several factors, such as inflation pressure, loads carried, vehicle speed, braking and acceleration tech- unique, type of road surface, and ambient temperature. Mechanical problems can also cause premature wear, including warped rims, worn suspension components, loose steering-head bearings and/or frame misalignment.
