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, and 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 blinks for 1 minute and stays on to indicate a

system malfunction.

■

Tire life

Any tire over 6 years old must be checked by a qualified technician even if it has sel-

dom or never been used or damage is not obvious.

■

Routine tire inflation pressure checks

The tire pressure warning system does not replace routine tire inflation pressure

checks. Make sure to check tire inflation pressure as part of your routine of daily

vehicle checks.

■

Low profile tires (vehicles with P225/45R18 91W tires)

Generally, low profile tires will wear more rapidly and tire grip performance will be

reduced on snowy and/or icy roads when compared to standard tires. Be sure to

use snow tires or tire chains on snowy and/or icy roads and drive carefully at a

speed appropriate for road and weather conditions.
