may
be

TIRE
ROTATION

Tires
wear

unevenly
and
become

unbalanced

according
to

running
dis

tance
Uneven
tire
wear
often
results

in
tire
noise

which
is
attributed
to
rear

axle

gears
bearing
etc
Meanwhile
the

front
tires
tend
to
wear

unevenly

because
of

improperly
aligned
front

wheel

Accordingly
to

equalize
tire
wear

it
is

necessary
to

rotate
tires

peri

odically

All
the
tires

including
the

spare
tire

are
of
