Tire Wear

Group 7.
1 Examine each tire tread for unusual wear patterns.
Refer to chart below for typical tread patterns.
2 Measure tread depth.
3 Check tire pressure and leak-test valve stems.
4 Check the Rim Flange wear on Aluminum Wheels
every time the wheel is replaced.
Note: The main causes of tire wear are faulty air
pressure, incorrect toe adjustment, and incorrect drive tire
alignment or thrust angles, which can cause pushing or
scrubbing of the steer tires. Feathered edges of the tires
is an early symptom of tire wear.
