2003 TOYOTA PRIUS wheel

223
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
Observe the following instructions.
Otherwise, an accident may occur re-
sulting in death or serious injuries.
Do not mix radial, bias belted, or
biasply tires on your vehicle, as
this may cause dangerous handling
characteristics resulting in loss of
control.
Do not use tires other than the
manufacturer ’s recommended size,
as this may cause dangerous han-
dling characteristics resulting in
loss of control.
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 177
in Section 5 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 177
in Section 5 for tire change procedure.
164.Rotating tires

224
When rotating tires, check for uneven
wear and damage. Abnormal wear is usu-
ally caused by incorrect tire pressure, im-
proper wheel alignment, outofbalance
wheels, or severe braking.
CAUTION
Do not include a compact spare tire
when rotating the tires. It is designed
for temporary use only.
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
If you need snow tires, select 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 w
heels
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.
NOTICE
Do not attempt to use a tire chain on
the compact spare tire, as it may re-
sult in damage to the vehicles as well
as the tire.

chains165.

225
TIRE CHAIN SELECTION
Use the tire chains of correct size.
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 lockedwheel
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.
166.Replacing wheels

226
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 wheels,
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.

Tread wear—The tread wear grade is a
comparative rating based on the wear rate
of the tire when tested under controlled
conditions on a specified government test
course. For example, a tire graded 150
would wear one and a half (11/2) times
as well on the government course as a
tire graded 100. The relative performance
of tires depends upon the actual condi-
tions of their use, however, and may de-
part significantly from the norm due to
variations in driving habits, service prac-
tices and differences in road characteris-
tics and climate.
Traction AA, A, B, C— The traction
grades, from highest to lowest, are AA, A,
B, and C, and they represent the tire’s
ability to stop on wet pavement as mea-
sured under controlled conditions on spe-
cified government test surfaces of asphalt
and concrete. A tire marked C may have
poor traction 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—
The temperature
grades are A (the highest), B, and C,
representing the tire’s resistance to the
generation of heat and its ability to dissi-
pate heat when tested under controlled
conditions on a specified indoor laboratory
test wheel. Sustained high temperature
can cause the material of the tire to de-
generate and reduce tire life, and exces-
sive temperature can lead to sudden tire
failure. The grade C corresponds to a lev-
el of performance which all passenger car
tires must meet under the Federal Motor
Vehicle Safety Standard No. 109. Grades
B and A represent higher levels of perfor-
mance 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 prop-
erly inflated and not overloaded. Exces-
sive speed, underinflation, or excessive
loading, either separately or in combina-
tion, can cause heat buildup and possible
tire failure.
