should be placed so that the vehicle is
balanced.
When replacing wheels, care
should be taken to ensure that they
are equivalent to those removed in
load capacity, dia meter, 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 allo w 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.511, 531)
WARNING
■Proper inflation is critical to save
tire performance
Keep your tires properly inflated. If the tires are not properly inflated,
the following conditions may occur
which could lead to an accident
resulting in death or serious injury:
●Excessive wear
●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 in 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.

Maintenance and care
Use only Toyota wheel nuts and
wrenches designed for use with
your aluminum wheels.
 When rotating, repairing or
changing your tires, check that
the wheel nuts are still tight after
driving 1600 km (1000 miles).
 Be careful not to damage the
aluminum wheels when using
tire chains.
 Use only Toyota genuine bal-
ance weights or equivalent and a
plastic or rubber hammer when
balancing your 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 seri - ous injury.
■When installing the wheel nuts
●Be sure to install the wheel nuts
with the tapered ends facing
inward. ( →P.597) Installing the nuts with the tapered ends facing out -
ward 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 tightened, 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 defecti ve 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 or other qualified service
shop. In addition, make sure to pur - chase your tire pressure warning
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 war ning valves and transmitters may not work properly
with non-genuine wheels.
