The serv ice life of tires depends on a lot of different things including proper
lation and balancing, correct tire pressure and driving style.

Rota ting tires for m ore even wear
If the front tires arc worn considerably more than the rear ones. rotate them shown 18 . All the tires will then last for about the same amount of time.
A
