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 your Toyota dealer.
