MAINTENANCE AND MINOR
ADJUSTMENTS
WHEEL MAINTENANCE
Wheel repairs that use welding, heating, or peening are not ap-
proved. All damaged wheels should be replaced.
WHEEL ATTACHING STUDS
If a broken stud is found, refer to WHEEL BEARING AND WHEEL
STUD in Section 3D (front) or 3E, 3E1 (rear) for replacement of it.
MATCHED TIRES AND WHEELS
Tires and wheels are matchmounted at the assembly plant.
This means that the radially stiffest part of the tire, or “high spot”,
is matched to the smallest radius or “low spot” of the wheel.
This is done to provide the smoothest possible ride.
The “high spot” of the tire is originally marked by paint dot (1) on
the outboard sidewall. This paint dot will eventually wash off the
tire.
The “low spot” of the wheel is originally marked by paint dot (2) on
the wheel rim-flange. Properly assembled, the wheel rim’s paint
dot should be aligned with the tire’s paint dot as shown in figure.
Whenever a tire is dismounted from its wheel, it should be re-
mounted so that the tire and wheel are matched. If the tire’s paint
dot cannot be located, a line should be scribed on the tire and
wheel before dismounting to assure that it is remounted in the
same position.
