Initial Inspection and Diagnostic Overview

Tires should be inspected and replaced when the following conditions are found:
a. They are worn to a point where 1.6 mm (1/16 inch) or less tread remains, or the cord or fabric is showing. To help detect this, tires may have built-in tread wear indicators that appear between the tread grooves when the tread is 1.6 mm (1/16 inch) or less. When the indicators appear in two or more adjacent grooves at three spots around the tire, replace the tire.
b. The tread or sidewall is cracked, cut or snagged deep enough to expose the cord or fabric.
c. The tire has a bump, bulge, or split. Slight sidewall indentations are normal and should not affect ride.
d. The tire has a puncture, cut, or other damage that cannot be correctly repaired because of the size or location of the damage.

NOTE: It is recommended that new tires be installed in pairs on the same axle. If it is necessary to replace only one tire, pair it with the tire having the most tread.
