CAUTION
n
Driving with snow tires
Observe the following precautions to reduce the risk of accidents.
Failing to do so may result in a loss of vehicle control and cause death or
serious injury.
l Use tires of the size specified for your vehicle.
l Maintain the recommended level of air pressure.
l Do not drive in excess of 75 mph (120 km/h) regardless of the type of
snow tires being used.
l Snow tires should be installed on all wheels.
n Driving with snow chains
Observe the following precautions to reduce the risk of accidents.
Failing to do so may result in the vehicle being unable to be driven safely,
and may cause death or serious injury.
l Do not drive in excess of the speed limit specified for the tire chains being
used or 30 mph (50 km/h), whichever is lower.
l Avoid driving on bumpy road surfaces or over potholes.
l Avoid sudden turns and braking.
l Slow down sufficiently before entering a curve to ensure that vehicle con-
trol is maintained.
NOTICE
nRepairing or replacing snow tires
Request repairs of and obtain replacement snow tires from Toyota dealers or
legitimate tire retailers.
This is because the removal and attachment of snow tires affects the opera-
tion of the tire pressure warning valves and transmitters.
n Fitting tire chains
The tire pressure warning valves and transmitters may not function correctly
when tire chains are fitted.

Maintenance and care
Ti
Installing tire pressure warning valves and transmitters
When replacing tires or wheels, ti re pressu
re warning valves and
transmitters must also be installed.
When new tire pressure warning valves and transmitters are installed,
new tire pressure warning valve and transmitter ID codes must be regis -
tered in the tire pressure warning computer and tire pressure warning
sy
stem must be initialized. Have tire pressure warning valve and trans -
mitter ID codes registered by your Toyota dealer.
Registering ID codes
The tire pressure warning valve and transmitter is equipped with a
unique ID code. When replacing a ti re pressure warning valve and
transmitter, it is necessary to register the ID code of tire pressure
warning valve and transmitter. Have the ID code registered by your
Toyota dealer.
nWhen to replace your vehicle's tires
Tires should be replaced if:
lYou have tire damage such as cuts, splits, cracks deep enough to
expose the fabric or bulges indicating internal damage
lA tire goes flat repeatedly or c annot 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.
nReplacing tires and wheels
If the ID code of the tire pressure warning valve and transmitter is not
registered, the tire pre ssure w

arning system will not work properly. After
driving for about 20 minutes, the ti re pressure warning light comes on
after blinking for 1 minute to indicate a system malfunction.
nTire life
Any tire over 6 years old must be checked by a qualified technician even
if

they have seldom or never been used or damage is not obvious.

260 4-3. Do-it-yourself maintenance
nIf the tread wears down below 0.16 in. (4 mm) on snow tires
The effectiveness of snow tires is lost.
nMaximum load of tire
Check that the maximum load of the replaced 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.
As for the maximum load of the tire, see the load limit at maximum cold
tire inflation pressure mentioned on the sidewall of the tire, and as for the
Gross Axle Weight Ratings (GAWR) , see the Certification Label. (→P.
264, 356).
nTire types
1 Summer tires
Summer tires are high-speed performance tires best suited to highway
driving under dry conditions. Since summer tires do not have the same
traction performance as snow tire s, summer tires are inadequate for
driving on snow-covered or icy roads. For driving on snow-covered
roads or icy roads, the use of snow tires is recommended. When
installing snow tires, be sure to replace all four tires.
2 All season tires
All season tires are designed to provide better traction in snow and to
be adequate for driving in most winter conditions, as well as for use
year round. All season tires, however, do not have adequate traction
performance compared with snow tires in heavy or loose snow. Also,
all season tires fall short in acceleration and handling performance
compared with summer tires in highway driving.
3Snow tires For driving on snow-covered roads or icy roads, we recommend using
snow tires. If you need snow tires, select tires of the same size, con-
struction and load capacity as the or iginally installed tires. Since your
vehicle has radial tires as original equipment, make sure your snow
tires also have radial construction. Do not install studded tires without
first checking local regulations for possible restriction. Snow tires
should be installed on all wheels. ( →P. 161)

Wheels
nWhen replacing wheels
The wheels of your Toyota are equipped with tire pressure warning
valves an
d transmitters that allow the tire pressure warning system to
provide advanced warning in the event of a loss in tire inflation pressure.
Whenever wheels are replaced, the tire pressure warning valves and
transmitters must be installed. ( →P. 2 5 9 )
If a wheel is bent, cracked or heavily corroded, it should be
replaced.

Otherwise, the tire may separate from the wheel or cause loss of
ha
ndling control.
nWheel selection
When replacing wheels, care shou ld
be taken to ensure that
they are equivalent to those removed in load capacity, diameter,
rim width, and offset.
Replacement wheels are available at your Toyota dealer.
Toyota does not recommend using:
l Whee
ls of different sizes or types
lUs
ed wheels
lBe
nt wheels that have been straightened
n Aluminum wheel precau
tions (if equipped)
l Use only
Toyota wheel nuts and wrench designed for use with
your aluminum wheels.
l When
rotating, repairing or changing your tires, check that the
wheel nuts are still tight after driving 1000 miles (1600 km).
l Be
careful not to damage the aluminum wheels when using
tire chains.
l Use only T
oyota genuine balance weights or equivalent and a
plastic or rubber hammer when balancing your wheels.

Maintenance and care
CAUTION
nWhen replacing wheels
lDo not use wheels that are a different size from those recommended in
the Owner’s Manual, as this may re
sult in loss of handling control.
lNever use an inner tube in a leaking wheel which is designed for a
tubeless tire. Doing so may result in an accident, causing death or seri-
ous injury.
NOTICE
nReplacing tire pressure warning valves and transmitters
lBecause tire repair or replacement may affect the tire pressure warn-
ing valves and transmitte rs, make sure to have tires serviced by your
Toyota dealer or other qualified service shop. In addition, make sure to
purchase your tire pressure warning valves and transmitters at your
Toyota dealer.
lEnsure that only genuine Toyota wheels are used on your vehicle.
Tire pressure warning valves and transmitters may not work properly
with non-genuine wheels.
