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 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.
■
If the tread on snow tires wears down below 0.16 in. (4 mm)
The effectiveness of snow tires is lost.
■
Tire rotation
It is not possible to rotate the tires, as the front and rear tire sizes are different.

Low profile 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 on snowy and/or icy roads and drive carefully at a speed appropriate
for road and weather conditions.
