Typical Wear Patterns
Incorrect Tire Pressure
Too high air pressure (Figure 8-3, View 1) gives rapid wear in
the middle of the tire. Too low air pressure (Figure 8-3, View
2) gives rapid shoulder wear.
Incorrect Camber
Incorrect camber gives abnormal wear on one half of the tire.
Incorrect Toe and Axle Alignment
Incorrect toe has a “scrubbing” effect on the front wheels that
shows in rapid shoulder wear or across the tire.
Incorrect axle alignment has a “scrubbing” effect on all
wheels.
Incorrect Caster and Wheel Imbalance
Incorrect caster or wheel imbalance shows as spot wear that
is either in the middle of the tire or extends to the shoulder.
This rapidly wears the mechanical parts of steering linkage,
kingpin and wheel bearing.
