Measure pattern depth at center of tread pattern. Measurements shall be taken at
several points due to uneven wear.
Replace the tire if any of the measurements is lower than the service limit. Make
sure the wheel is properly balanced when a new tire is replaced.
Service Limits:
Front Wheel 0.8 mm
Rear Wheel 0.8 mm
Check Tread Pattern for Wear
Check tires before each riding. In case of finding a transverse line (minimum
pattern depth), nail or glass chip on the tire, or crack line on the side wall of tire,
go to Kymco dealer for replacing with new one. Excessive wear of tire tread
pattern will result in widened tread which is more prone to be punctured.
