2B-2 WHEEL ALIGNMENT
DIAGNOSIS
TIRE DIAGNOSIS
Irregular and Premature Wear
Irregular and premature tire wear has many causes.
Some of them are incorrect inflation pressures, lack of
regular rotation, poor driving habits, or improper wheel
alignment.
Rotate the tires if :
lThe front tire wear is different from the rear.
lThe left and right front tire wear is unequal.
lThe left and right rear tire wear is unequal, Check
wheel alignment if :
lThe left and right front tire wear is unequal.
lThe wear is uneven across the tread of either front
tire.
lThe front tire treads are scuffed with “feather” edges
on the side of the tread ribs or blocks.
Tread Wear Indicators
The original equipment tires have built-in tread wear
indicators to show when the tires need replacement.
These indicators appear as bands when the tire tread
depth becomes shallow. Tire replacement is
recommended when the indicators appear in three or
more grooves at six locations.
Radial Tire Waddle
Waddle is side-to-side movement at the front or rear of
the vehicle. It is caused by the steel belt not being straight
within the tire, or by excessive lateral runout of the tire
or wheel.
The vehicle must be road tested to determine which end
of the vehicle has the faulty tire. The rear end of the
vehicle will shake from side to side or “waddle” if the
waddle tire is on the rear of the vehicle. From the driver’s
seat, it feels as though someone is pushing on the side
of the vehicle. If the faulty tire is on the front of the vehicle,
the waddle is more visual. The front sheet meld appears
to be moving back and forth, and the drivers seat feels
like the pivot point in the vehicle.
Waddle can be diagnosed using the method of
substituting known good tire and wheel assemblies on
the problem vehicle
1. Road test the vehicle to determine if the waddle is
coming from the front or the rear of the vehicle.
2. Install good tires and wheels from a similar vehicle in
place of those on the offending end of the problem
vehicle. If the source of the waddle is not obvious,
change the rear tires.
