Replace the tires if the treadwear
indicators are showing on a tire.
■ When to replace your vehicle’s
tires
Tires should be replaced if:
● The treadwear indicators are
showing on a tire.
● You have tire damage such as
cuts, splits, cracks deep enough
to expose the fabric, and bulges
indicating internal damage.
● A tire goes flat repeatedly or can-
not be properly repaired due to the
size or location of a cut or other
damage.
If you are not sure, consult with your
Toyota dealer.
■ Tire life
Any tire over 6 years old must be
checked by a qualified technician
even if it has seldom or never been
used or damage is not obvious.
■ Proper storage of the spare tire
As an improperly stored spare tire
may cause damage to the wire
cable that holds it, check that the
spare tire is stored properly on a
daily basis.
● If the stored spare tire appears to
be slanted or rattles while driving,
the spare tire may not be properly
stored. Store the spare tire again
by performing the following tire
change procedure correctly:
1
If the spare tire is slanted, the
hoist assembly may be stuck in
the wheel opening. If the spare
tire rattles while driving, it may
not be fully raised. Lower the
spare tire to the ground and
make sure that the hoist assem-
bly is perpendicular to the wheel
opening.
2
Raise the tire slowly and steadily
until a click is heard and the jack
handle skips.
If the spare tire cannot be lowered,
the wire cable may be severed.
Have the vehicle inspected at your
Toyota dealer.
■ Maximum load of tire
Check that the number given by
dividing the maximum load by 1.10
of the replacement tire is greater
than 1/2 of the Gross Axle Weight
Ratings (GAWR) of either the front
axle or the rear axle, whichever is
greater.
For the GAWR, see the Certification
Label.
For the maximum load of the tire,
see the load limit at maximum cold
tire inflation pressure mentioned on
the sidewall of the tire. (

■ Tire types
● Summer tires
Summer tires are high-speed perfor-
mance tires best suited to highway
driving under dry conditions. Since
summer tires do not have the same
traction performance as snow tires,
summer tires are inadequate for
