Maintenance and care
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 refer red 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 chang ing your tires, check that the
wheel nuts are still tight afte r driving 1000 miles (1600 km).
● Be careful not to damage the aluminum wheels when using
tire chains.
● Use only Toyota genuine balan ce weights or equivalent and a
plastic or rubber hammer when balancing your wheels.

■When replacing wheels
The wheels of your Toyota are equipped with tire pressure warning
valves and transmitters that allow the tire pressure warning sy stem to
provide advanced warning in the event of a loss in tire inflati on pressure.
Whenever wheels are replaced, the tire pressure warning valves and
transmitters mus t be installed. (P. 3 4 6 )
WARNING
■When replacing wheels
●Do not use wheels that are a different size from those recommen ded in
the Owner’s Manual, as this may result in loss of handling cont rol.
●Never use an inner tube in a leaking wheel which is designed fo r a
tubeless tire. Doing so may result in an accident, causing deat h or seri-
ous injury.
■When installing the wheel nuts
●Never use oil or grease on the wheel bolts or wheel nuts.
Oil and grease may cause the wheel nuts to be excessively tight ened,
leading to bolt or disc wheel damage. In addition, the oil or g rease can
cause the wheel nuts to loosen and the wheel may fall off, caus ing an
accident and resulting in death or serious injury. Remove any o il or
grease from the wheel bolts or wheel nuts.
●Be sure to install the wheel nuts with
the tapered ends facing inward.
Installing the nuts with the tapered
ends facing outward can cause the
wheel to break and eventually cause
the wheel to come off while driving,
which could lead to an accident
resulting in death or serious injury.
