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:
z Wheels of different sizes or types
z Used wheels
z 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, the tire pressure warning valves and transmitters must be
installed. ( →P.333)
WARNING
●Uneven wear
●Poor handling
●Possibility of blowouts resulting
from overheated tires
●Air leaking from between tire and
wheel
●Wheel deformation and/or tire dam-
age
●Greater possibility of tire damage
while driving (due to road hazards, expansion joints, sharp edges on the road, etc.)
NOTICE
■When inspecting and adjusting tire inflation pressure
Be sure to put the tire valve caps back
on. If a valve cap is not installed, dirt or moisture may get into the valve and
cause an air leak, resulting in decreased tire inflation pressure.
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.

■When removing the wheel orna-
ment (vehicles with a wheel cap clip)
Remove the wheel ornament using the
wheel cap clip*.*: The wheel cap clip is installed in the
glove box. ( →P.293)
zUse only Toyota wheel nuts and
wheel nut wrenches designed for
use with your aluminum wheels.
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 serious injury.
■When installing the wheel nuts
●Be sure to install the wheel nuts with the tapered ends facing inward ( →P.394). 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.
●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
grease can cause the wheel nuts to loosen and the wheel may fall off, causing an accident and resulting in
death or serious injury. Remove any oil or grease from the wheel bolts or wheel nuts.
■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.
NOTICE
■Replacing tire pressure warning valves and transmitters
●Because tire repair or replacement may affect the tire pressure warning valves and transmitters, make sure
to have tires serviced by any autho- rized Toyota retailer or Toyota authorized repairer, or any reliable
repairer. In addition, make sure to purchase your tire pressure warn-ing valves and transmitters at any
authorized Toyota retailer or Toyota authorized repairer, or any reliable repairer.
●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.
