When to replace your vehicle’s tires
Tires should be replaced if:
l
You have tire damage such as cuts, splits, cracks deep enough to
expose the fabric or bulges indicating internal damage
l
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 Toyota dealer.
n
Replacing tires and wheels
If the ID code of the tire pressure warning valve and transmitter is not regis-
tered, the tire pressure warning system will not work properly. After about 20
minutes, the tire pressure warning light comes on after blinking for 1 minute
to indicate a system malfunction.
n
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.
n
If the tread wears down 0.16 in. (4 mm) or more on snow tires
The effectiveness of snow tires is lost.
n
If you press the tire pressure warning reset switch accidentally
If initialization is performed, adjust the tire inflation pressure to the specified
level and initialize the tire pressure warning system again.
