There are two ways in which every wheel must be
balanced--
Statically-- Figure 1
Dynamically--Figure 2
WHEEL AND TIRE BALANCE
Wheel and tire balance is essential to prevent uneven
tire wear and high speed wheel tramp, both of which
contribute to poor handling, riding discomfort and excessive
wear in steering gear and front end parts.
Tires and tubes are balanced at time of assembly to car
at the factory.
The tire side walls are marked with a red dot to
indicate the position in which the valve stem should be
placed in order to preserve the original balance.
FIGURE 1
Tire wear or tire repair will, however, affect the
balance. This is relatively unimportant on rear tires but
very important on front tires.
Although tires and wheels are balanced when they
leave the factory, subsequent tire wear causes them to go
out of balance. T o maintain proper balance and assist in
prolonging tire life, it is the tire manufacturers' recommendation
that the wheel and tire assemblies be check
for balance every 2,500 miles and whenever a tire is
repaired or recapped.
BALANCING THE WHEEL
AND TIRE
Wheel balance is the equal distribution of weight of
the wheel and tire assembly around the axis of rotation
(static balance) and through the center line of the wheel
and tire (dynamic balance).
FIGURE 2
Wheel unbalance is the principal cause of tramp and
contributes to other steering difficulties.
