When to replace your vehicle’s tires
Tires should be replaced if:
●
The treadwear indicators are showing on a tire.
●
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 malfunc-
tion.
■
Tire life
Any tire over 6 years old must be checked by a qualified technician even if it has seldom
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.
■
Maximum load of tire
Check that the number given by dividing the maximum load by 1.10 of the replacement
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 men-
tioned on the sidewall of the tire. (
