Keep your tire pressures at the proper
level.
The recommended cold tire pressures,
tire size and the vehicle capacity weight
are also given in Part 8. They are also on
the tire pressure label as shown.
You should check the tire pressures every
two weeks, or at least once a month. And
don't forget the spare!
Incorrect tire pressure can reduce tire
life and make your vehicle less safe to
drive.Low tire pressure results in excessive
wear, poor handling, reduced fuel econo-
my, and the possibility of blowouts from
overheated tires. Also, low tire pressure
can cause poor sealing of the tire bead.
If the tire pressure is excessively low,
there is the possibility of wheel deforma-
tion and/or tire separation.
High tire pressure produces a harsh ride,
handling problems, excessive wear at the
center of the tire tread, and a greater
pos-
sibility of tire damage from road hazards.
If a tire frequently needs refilling, have it
checked by your Toyota dealer.
The following instructions for check-
ing tire pressure should be observed:

The pressure should be checked
only when the tires are cold. If your
vehicle has been parked for at least 3
hours and has not been driven for
more than 1.5 km or 1 mile since, you
will get an accurate cold tire pressure
reading.

Always use a tire pressure gauge.
The appearance of a tire can be mis-
leading. Besides, tire pressure that
are even just a few pounds off can de-
grade handling and ride.

Do not bleed or reduce tire pres-
sure after driving. It is normal for the
tire pressure to be higher after driving.

Never exceed the vehicle capacity
weight. The passenger and luggage
weight should be located so that the
vehicle is balanced.

Be sure to reinstall the tire inflation
valve caps. Without the valve caps,
dirt or moisture could get into the valve
core and cause air leakage. If the caps
have been lost, have new ones put on
as soon as possible.

CHECKING YOUR TIRES
Check the tire tread for the tread wear
indicators. If the indicators show, re-
place the tires.
The tires on your Toyota have built-in
tread wear indicators to help you know
when the tires need replacement. When
the tread depth wears to 1.6 mm (0.06 in.)
or less, the indicators will appear. If you
can see the indicators in two or more adja-
cent grooves, the tire should be replaced.
The lower the tread, the higher the risk of
skidding.
The effectiveness of snow tires is lost
if the tread wears down below 4 mm
(0.16 in.).Check the tires regularly for damage
such as cuts, splits and cracks. If any
damage is found, consult with a tech-
nician and have the tire repaired or re-
placed.
Even if the damage does not appear seri-
ous, a qualified technician should ex-
amine the damage. Objects which have
penetrated the tire may have caused in-
ternal damage.
Any tires which are over six years old
must be checked by a qualified techni-
cian even if damage is not obvious.
Tires deteriorate with age even if they
have never or seldom been used.
This
also applies to the spare tire and tires
stored for future use.
REPLACING YOUR TIRES
When replacing a tire, use only the
same size and construction as origi-
nally installed and with the same or
greater load capacity.
Using any other size or type of tire may se-
riously affect handling, ride, speedomeet-
er/odometer calibration, ground clear-
ance, and clearance between the body
and tires or snow chains.
CAUTION

Do not mix radial, bias belted, or
bias-ply tires on your vehicle. It
can cause dangerous handling
characteristics, r esulting in loss of
control.

Do not use tire or wheels other
than the manufacturer's recom-
mended size.!
Toyota recommends all four tires, or at
least both of the front or rear tires be
replaced at a time as a set.
See If you have a flat tireº in Part 4 for tire
change procedure.
When a tire is replaced, the wheel
should always be balanced.
An unbalanced wheel may affect vehicle
handling and tire life. Wheels can get out
of balance with regular use and should
therefore be balanced occasionally.
When replacing a tubeless tire, the air
valve should also be replaced with a
new one.

To equalize tire wear and help extend
tire life, Toyota recommends that you
rotate your tires every 12000 km (7500
miles). However, the most appropriate
timing for tire rotation may vary ac-
cording to your driving habits and
road surface conditions.
See If you have a flat tireº in Part 4 for tire
change procedure.
When rotating tires, check for even wear
and damage. Abnormal wear is usually
caused by incorrect tire pressure, improp-
er wheel alignment, out-of-balance
wheels, or severe braking. WHEN TO USE SNOW TIRES OR
CHAINS
Snow tires or chains are recom-
mended when driving on snow or ice.
On wet or dry roads, conventional tires
provide better traction than snow tires.
SNOW TIRE SELECTION
If you need snow tires, select tires of
the same size, construction and load
capacity as the original tires on your
Toyota.
Do not use tires other than those men-
tioned above.
Do not install studded tires
without first checking local regulations for
possible restrictions.
SNOW TIRE INSTALLATION
Snow tires should be installed on all
wheels.
Installing snow tires on the front wheels
only can lead to an excessive difference
in road grip capability between the front
and rear tires which would cause loss of
vehicle control.
When storing removed tires, you should
store them in a cool dry place.
Mark the direction of rotation and be sure
to install them in the same direction when
replacing.
CAUTION

Do not drive with the snow tires
incorrectly inflated.

Never drive over 120 km/h (75
mph) with any type of snow tires.!
TIRE CHAIN SELECTION
Use the tire chains of correct size and
type.
Use SAE Class Sº type radial tire chains
except radial cable chains or V-bar type
chains.
Regulations regarding the use of tire
chains vary according to location or
type of r oad, so always check them be-
fore installing chains.
CHAIN INSTALLATION
Install the chains on the front tires as
tightly as possible. Do not use tire
chains on the rear tires. Retighten
chains after driving 0.5 '1.0 km
(1/4 '1/2 mile).
When installing chains on your tires, care-
fully follow the instructions of the chain
manufacturer.

After driving your vehicle the first 1600
km (1000 miles), check that the wheel
nuts are tight.

If you have rotated, repaired, or
changed your tires, check that the
wheel nuts are still tight after driving
1600 km (1000 miles).

When using tire chains, be careful not
to damage the aluminum wheels.

Use only the Toyota wheels, nuts and
wrench designed for your aluminum
wheels.

When balancing your wheels, use only
Toyota balance weights or equivalent
and a plastic or rubber hammer.

As with any wheel, periodically check
your aluminum wheels for damage. If
damaged, replace immediately.

218This
information has been prepared in ac-
cordance with regulations issued by the
National Highway Traffic Safety Adminis-
tration of the U.S. Department of Trans-
portation. It provides the purchasers and/
or prospective purchasers of Toyota
vehicles with information on uniform tire
quality grading.
Your Toyota dealer will help answer any
questions you may have as you read this
information.
DOT quality gradesÐAll passenger
vehicle tires must conform to Federal
Safety Requirements in addition to
these grades. These quality grades are
molded on the sidewall.
Treadwear ÐThe treadwear grade is a
comparative rating based on the wear
rate of the tire when tested under con-
trolled conditions on a specified govern-
ment test course. For example, a tire
graded 150 would wear one and a half
(1-1/2) times as well on the government
course as a tire graded 100. The relative
performance of tires depends upon the
actual conditions of their use, however,
and may depart significantly from the
norm due to variations in driving habits,
service practices and differences in road
characteristics and climate. Traction A, B, CÐThe traction grades,
from highest to lowest, are A, B, and C,
and they represent the tire's ability to stop
on wet pavement as measured under
controlled
conditions on specified govern-
ment test surfaces of asphalt and con-
crete. A tire marked C may have poor trac-
tion performance.
Warning: The traction grade assigned to
this tire is based on braking (straight
ahead) traction tests and does not include
cornering (turning) traction.
Temperature A, B, C ÐThe temperature
grades are A (the highest), B, and C, rep-
resenting the tire's resistance to the gen-
eration of heat and its ability to dissipate
heat when tested under controlled condi-
tions on a specific indoor laboratory test
wheel. Sustained high temperature can
cause the material of the tire life, and ex-
cessive temperature can lead to sudden
tire failure. The grade C corresponds to a
level of performance which all passenger
car tires must meet under the Federal Mo-
tor Vehicle Safety Standard No. 109.
Grades B and A represent higher levels of
performance on the laboratory test wheel
than the minimum required by law. Warning: The temperature grades for this
tire
are established for a tire that is proper-
ly inflated and not overloaded. Excessive
speed, underinflation, or excessive load-
ing, either separately or in combination,
can cause heat buildup and possible tire
failure.
