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 is not registered, the system will not work properly. After about 1 hour,
the tire pressure warning light blinks to indicate a system malfunction.
■
Tire life
Any tire over 6 years old must be checked by a qualified technician even if they
have seldom or never been used or damage is not obvious.
■
If the tread wears down below 0.16 in. (4 mm) on snow tires
The effectiveness of snow tires is lost.
