Maintenance and care
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 any authorized Toyota retailer or
Toyota authorized repairer, or any
reliable repairer.
*: Conventionally referred to as offset.
Toyota does not recommend using
the following:
 Wheels of different sizes or types
 Used wheels
 Bent wheels that have been
straightened
■When replacing wheels
The wheels of your vehicle are equipped with tire pressure warning valves and
transmitters that allow the tire pressure warning system to provide advance warning in the event of a loss in tire
inflation pressure. Whenever wheels are replaced, tire pressure warning valves and transmitters must be installed.
( P.479)
Wheels
If a wheel is bent, cracked or
heavily corroded, it should be
replaced. Otherwise, the tire
may separate from the wheel
or cause a loss of handling
control.

WARNING
■When replacing wheels
●Do not use wheels that are a differ-
ent size from those recommended in the Owner’s Manual, as this may result in a loss of handling control.
●Never use an inner tube in a leak-ing wheel which is designed for a
tubeless tire. Doing so may result in an accident, causing death or seri-ous injury.
■Wheel bolts
Observe the following precautions to
reduce the risk of death or serious injury:
●Do not over tighten.
●Never use oil or grease on the
wheel bolts. Oil and grease may cause the wheel bolts to be exces-sively tightened, leading to bolt or
disc wheel damage. In addition, the oil or grease can cause the wheel bolts to loosen and the wheel may
fall off, causing a serious accident. Remove any oil or grease from the wheel bolts.
●If there are any cracks or deforma-tions in the wheel bolts, or if the sur-
face treatment becomes worn, have the wheel bolts replaced at your any authorized Toyota retailer or
Toyota authorized repairer, or any reliable repairer. Failure to follow these precautions could cause the
wheel bolts to loosen and the tire to fall off, resulting in death or serious injury.
■Use of defective wheels prohib-ited
Do not use cracked or deformed wheels.Doing so could cause the tire to leak
air during driving, possibly causing an accident.
