TIRE AND WHEEL BALANCE
It is recommended that a two plane dynamic bal­
ancer be used when a wheel and tire assembly re­
quire balancing. Static should be used only when a
two plane balancer is not available.
For static imbalance, find location of heavy spot
causing imbalance. Counter balance wheel directly
opposite the heavy spot. Determine weight required
to counterbalance the area of imbalance. Place half of
this weight on the inner rim flange and the other
half on the outer rim flange (Fig. 5 and 6). Off-vehi­
cle balancing is necessary.
Wheel balancing can be accomplished with either
on or off vehicle equipment. When using on-vehicle
balancing equipment, follow these precautions:
• Limited-slip rear axle differential, remove the op­
posite wheel/tire
® Before balancing the wheels/tires on a vehicle
equipped with a transfer case, disconnect the drive
shafts
MATCH MOUNTING
Match mounting means that the high spot of the
tire is matched to the low spot on the wheel rim.
This technique is used to ' reduce run-out in the
wheel/tire assembly. The high spot on the tire is
marked with a paint mark or a bright colored adhe­
sive label on the outboard sidewall. The low spot on
the rim is at the valve stem location on the wheel
rim. ,
Before dismounting a tire from its wheel, a refer­
ence mark should be placed on the tire at the valve
stem location. This reference will ensure that it is re­
mounted in the original position on the wheel.
