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 warn ing 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. 374)
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.
