Treadwear indicators are one way to tell when it is time for new tires. Treadwear indicators appear when the tires have only 1.6mm (1/16 in) or less of tread remaining. See Tire Inspection on page 10‑57 and Tire Rotation on page 10‑57 for more information.

The rubber in tires ages over time. This also applies for the spare tire, if the vehicle has one, even if it is never used.
