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 on snow tires wears down below 0.16 in. (4 mm) on snow tires

The effectiveness of the tire as snow tires is lost.

■

Maximum load of tire

Check that the number given by dividing the maximum load by 1.10 of the replace-

ment tire is greater than 1/2 of the Gross Axle Weight Ratings (GAWR) of either

the front axle or the rear axle, whichever is greater.

For the GAWR, see the Certification Label.

For the maximum load of the tire, see the load

limit at maximum cold tire inflation pressure

mentioned on the sidewall of the tire.
