Kawasaki Ninja Service Manual: Tire Tread Wear Inspection

Kawasaki Ninja Service Manual / Periodic Maintenance / Periodic Maintenance Procedures / Wheels/Tires / Tire Tread Wear Inspection

As the tire tread wears down, the tire becomes more susceptible to puncture and failure. An accepted estimate is that 90% of all tire failures occur during the last 10% of tread life (90% worn). So it is false economy and unsafe to use the tires until they are bald.

If any measurement is less than the service limit, replace the tire (see Tire Removal/Installation in the Wheels/Tires chapter).
