Tire Wear
For further information refer to Function 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 tire is replaced.
Note: Be advised, the main causes of tire wear are
faulty air pressure, incorrect toe adjustment, and incor-
rect drive tire alignment or thrust angles, which causes
pushing or scrubbing of the steer tires. Feathered edges
of the tires is and early symptom of tire wear.
