Maintenance and care
Wheels
■When replacing wheels
The wheels of your Toyota are equipped with tire pressure warning
valves and transmitters (except for spare tire) 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 transmitte rs must be installed. (P. 495)
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 offset.
Replacement wheels are available at your Toyota dealer.
Toyota does not recommend using:
●Wheels of different sizes or types
● Used wheels
● Bent wheels that have been straightened
■ Wheel precautions
●Use only Toyota wheel nuts and wrench designed for use with
your aluminum wheels.
● When rotating, repairing or changing your tires, check that the
wheel nuts are still tight after driving 100 miles (160 km).
● Be careful not to damage the aluminum wheels when using
tire chains.
● Use only Toyota genuine balance weights or equivalent and a
plastic or rubber hammer when balancing your wheels.

506 4-3. Do-it-yourself maintenance
CAUTION
■When replacing wheels
●Do not use wheels that are a different size from those recommended in
the Owner’s Manual, as this may result in loss of handling control.
●Never 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
■Replacing tire pressure warning valves and transmitters
●Because tire repair or replacement may affect the tire pressure warn-
ing valves and transmitters, make su re 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.
●Ensure that only genuine Toyota wheels are used on your vehicle.
Tire pressure warning valves and transmitters may not work properly
with non-genuine wheels.
