Keep your tire pressures at the proper
level.
The recommended cold tire pressures, tire
size and the vehicle capacity weight are
given on page 268 in Section 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
do not 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 w
heel 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
possibility of tire damage from road haz-
ards.
If a tire frequently needs ref illing, have it
checked by your Toyota dealer.
The following instructions for checking
tire pressure should be observed:
The pressure should be checked only
when the tires are cold. If your ve-
hicle 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 pressures that
are even just a few pounds off can
degrade ride and handling.
Take special care when adding air to
the compact spare tire. The smaller
tire size can gain pressure very quick-
ly. Add compressed air in small quanti-
ties and check the pressure often until
it reaches the specified pressure.
Do not bleed or reduce tire pressure
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.

Tread wear indicator
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
adjacent grooves, the tire should be re-
placed. The lower the tread, the higher
the risk of skidding.Vehicles equipped with P215/50ZR17
tires:
Your Toyota has been fitted with
specially developed tires which provide ex-
ceptional dynamic performance under gen-
eral road conditions. However your riding
comfort may worsen a little and road
noise may increase during driving. You
may also notice that your tires will wear
more rapidly and tire grip performance will
be reduced on the snowy and/or icy roads
when compared to standard tires. Be sure
to have snow tires or tire chains on the
snowy and/or icy roads and drive carefully
with the speed appropriate for road condi-
tions.
NOTICE
Low profile tire like P215/50ZR17 may
have greater damage than usual tires
to its tire wheel when receiving im-
pact from the road surface. Therefore,
pay attention to the followings.
Be sure to use with proper tire
pressure. If the tire pressure is low,
the tire may have a greater damage.
For detailed information about tire
pressure, see page 272 in Section
8.
Avoid driving onto high, sharp
edged objects and other road haz-
ards. Failure to do so can lead to
severe tire damage.
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 techni-
cian and have the tire repaired or re-
placed.

2492003 MY COROLLA MATRIX_U (OM12767U)
Even if the damage does not appear seri-
ous, a qualified technician should examine
the damage. Objects which have pene-
trated the tire may have caused internal
damage.
Any tires which are over 6 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
Two wheel drive models—When replac-
ing a tire, use only the same size and
construction as originally installed and
with the same or greater load capacity.
Four wheel drive models—When replac-
ing tires, make sure all the tires are the
same brand. Only use the same size,
construction and tread patterns as the
originally installed tires, with the same
or greater load capacity.
Using any other size or type of tire may
seriously affect handling, ride, speedome-
ter/odometer calibration, ground clearance,
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 char-
acteristics, resulting in loss of con-
trol.
Do not use tire or wheels other
than the manufacturer ’s recom-
mended size.
Toyota recommends all four tires, or at
least both front or rear tires be re-
placed as a set.
See “If you have a flat tire” on page 202
in Section 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 according to the main-
tenance schedule. (For scheduled main-
tenance information, please refer to the
“Scheduled Maintenance Guide” or
“Owner ’s Manual Supplement”.) Howev-
er, the most appropriate timing for tire
rotation may vary according to your
driving habits and road surface condi-
tions.
See “If you have a flat tire” on page 202
in Section 4 for tire change procedure.

When rotating tires, check for uneven
wear and damage. Abnormal wear is usu-
ally caused by incorrect tire pressure, im-
proper wheel alignment, out of balance
wheels, or severe braking.
CAUTION
Do not include a compact spare tire
when rotating the tires. It is designed
for temporary use only.
Turning direction
Ty p e A
Ty p e B
Vehicles equipped with P215/50ZR17
tires: You have directional tires, and a
turning indicator marked on the side
wall. Using tires on the wrong side of
the vehicle will impair tire performance. WHEN TO USE SNOW TIRES OR
CHAINS
Snow tires or chains are recommended
when driving on snow or ice.
On wet or dry roads, conventional tires
provide better traction than snow tires.
SNOW TIRE SELECTION
Two wheel drive models—If you need
snow tires, select the same size,
construction and load capacity as the
original tires on your Toyota.
Four wheel drive models—If you need
snow tires, select the same brand, size,
construction, tread patterns and load
capacity as the original tires on your
To y o t a .
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 could 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 “S” 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 road, so always check them
before 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.
If wheel covers are used, they will be
scratched by the chain band, so remove
the covers before putting on the chains.CAUTION
Do not exceed 50 km/h (30 mph) or
the chain manufacturer ’s recom-
mended speed limit, whichever is
lower.
Drive carefully avoiding bumps,
holes, and sharp turns, which may
cause the vehicle to bounce.
Avoid sharp turns or locked wheel
braking, as use of chains may ad-
versely affect vehicle handling.
When driving with chains installed,
be sure to drive carefully. Slow
down before entering the curves to
avoid losing control of the vehicle.
Otherwise an accident may occur.
NOTICE
Do not attempt to use a tire chain on
the compact spare tire, as it may re-
sult in damage to the vehicle as well
as the tire.

WHEN TO REPLACE YOUR WHEELS
If you have wheel damage such as
bending, cracks or heavy corrosion, the
wheel should be replaced.
If you fail to replace damaged wheels, the
tire may slip off the wheel or cause loss
of handling control.
WHEEL SELECTION
When replacing wheels, care should be
taken to ensure that the wheels are re-
placed by ones with the same load ca-
pacity, diameter, rim width, and offset.
This must be observed on compact spare
tire, too.
Correct replacement wheels are available
at your Toyota dealer.
A wheel of a different size or type may
adversely affect handling, wheel and bear-
ing life, brake cooling, speedometer/odom-
eter calibration, stopping ability, headlight
aim, bumper height, vehicle ground clear-
ance, and tire or snow chain clearance to
the body and chassis. Replacement with used wheels is not rec-
ommended as they may have been sub-
jected to rough treatment or high mileage
and could fail without warning. Also, bent
wheels which have been straightened may
have structural damage and therefore
should not be used. Never use an inner
tube in a leaking wheel which is designed
for a tubeless tire.When installing aluminum w
heels,
check that the wheel nuts are tight
after driving your vehicle the first 1600
km (1000 miles).
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 wheel 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.
