When to replace your vehicle's tires

Tires should be replaced if:

●
bulges indicating internal damage
A tire goes flat repeatedly or cannot be properly repaired due to the size or location of

repairer, or any reliable repairer.
Replacing tires and wheels (vehicles with the tire pressure warning system)
■
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 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.
