ically
Wheel
and
Tire

Proper
tire

balance
is

necessary

when

driving
the
vehicle

at

high

speeds

Consequently
the

wheel
and

tire

assembly
should
be

properly
re

balanced
whenever

puncture

re

paired

The
wheel
and

tire

assembly
be

comes
out
of
ba1ance

according
to

uneven
tire
wear

Severe
acceleration

and

braking
or
fast

cornering
is
the

cause
of

wear

on
tire

resulting
in

unbalance
of
tire
and
wheel

assembly

The

symptom
of
unbalance

appears

as
