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 any authorized Lexus dealer or repairer, or another
duly qualified and equipped professional.
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 10
minutes, the tire pressure warning light blinks for 1 minute and stays on to indicate a
system malfunction.

they have seldom or never been used or damage is not obvious.
The compact spare tire could be deformed gradually in the long term even if

rized Lexus dealer or repairer, or another duly qualified and equipped profes-
sional if it is over 5 years.

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