Selecting tire chainsSnow chains can be mounted on 16- and 17-inch tires. They cannot
be mounted on 18-inch tires. Use the correct snow chain size when
mounting the snow chains . Chain size is regulated for each tire size.
Side chain: 0.12 in. (3 mm) in diameter
0.39 in. (10 mm) in width
1.18 in. (30 mm) in length
Cross chain: 0.16 in. (4 mm) in diameter
0.55 in. (14 mm) in width
0.98 in. (25 mm) in length
Regulations on the use of snow chains
● Regulations regarding the use of tire chains vary according to loca-
tion and type of road. Always check local regu lations before install-
ing chains.
● Install the chains on the front tires.
● Retighten the chains after drivi ng 1/4 - 1/2 mile (0.5 - 1.0 km).
■When driving the vehicle
Accelerate the vehicle slowly and drive at a reduced speed suit-
able to road conditions.
■ When parking the vehicle
Park the vehicle and move the shift lever to P (automatic trans-
mission), 1 or R (manual transmission) without setting the park-
ing brake. The parking brake may freeze up, preventing it from
being released. If necessary, block the wheels to prevent inad-
vertent sliding or creeping.

4-3. Do-it-yourself maintenance
Wheels
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
handling control.
■Wheel selection
When replacing wheels, care should be taken to ensure that
they are equivalent to those removed in load capacity, diameter,
rim width, and inset*.
Replacement wheels are available at your Toyota dealer.
*: Conventionally referred to as “offset”.
Toyota does not recommend using:
●Wheels of different sizes or types
● Used wheels
● Bent wheels that have been straightened
■ Aluminum wheel precautions
●Use only Toyota wheel nuts and wrenches designed for use
with your aluminum wheels.
● When rotating, repairing or changing your tires, check that the
wheel nuts are still tight after driving 1000 miles (1600 km).
● Be careful not to damage the aluminum wheels when using
tire chains.
● Use only Toyota genuine bal ance weights or equivalent and
use a plastic or rubber hammer when balancing your wheels.

Uniform Tire Quality GradingThis information has been prepared in accordance with regulations
issued by the National Highway Tr affic Safety Administration of the
U.S. Department of Transportation.
It provides the purchasers and/or prospective purchasers of Toyota
vehicles with information on uniform tire quality grading.
Your Toyota dealer will help answ er any questions you may have as
you read this information.
■ DOT quality grades
All passenger vehicle tires mu st conform to Federal Safety
Requirements in addition to these grades. Quality grades can be
found where applicable on the tire sidewall between tread shoulder
and maximum section width.
For example: Treadwear 200 Traction AA Temperature A
