Tires
wear

unevenly

according
to

tance
Uneven
tire
wear
often
results

in
tire
noise

which
is
attributed
to
rear

axle

gears

etc
Meanwhile
the

front
tires
tend
to
wear

unevenly

because
of

improperly

Accordingly
to

equalize
tire

it
is

necessary
to

rotate
tires

peri

are

INSPECTION

WHEEL
BALANCE

The

wheel
arid
tire

asSembly
should

be

kept
balanced

statically
and

dynam

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
is

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

tramp
vehicle
shake
and

steering

malfunction

To

correct
unbalance

use
