When to replace your vehicle±s tires

Tires should be replaced if:

●

You have tire damage such as cuts, splits, cracks deep enough to expose the

fabric or bulges indicating internal damage

●

A tire goes flat repeatedly or cannot be properly repaired due to the size or

location of a cut or other damage

If you are not sure, consult with your Lexus dealer.

■

Replacing tires and wheels

If the ID code of the tire pressure warning valve and transmitter is not registered,

the tire pressure warning system will not work properly. After driving for about 20

minutes, the tire pressure warning light comes on after blinking for 1 minute to indi-

cate a system malfunction.

■

Tire life

Any tire over 6 years old must be checked by a qualified technician even if they

have seldom or never been used or damage is not obvious.

■

If the tread wears down 0.16 in. (4 mm) or more on snow tires

The effectiveness of snow tires is lost.
