causing death or serious injury.
lExcessive wear
lUneven wear
lPoor handling
lPossibility of blowouts resu lting from overheated tires

Maintenance and care
Wheels
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.
nWheel selection
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 your Toyota dealer.
*: Conventionally referred to as “offset”.
Toyota does not recommend using:
lWheels of different sizes or types
l Used wheels
l Bent wheels that have been straightened
n Aluminum wheel precautions (if equipped)
lUse only Toyota wheel nuts and wrench designed for use with
your aluminum wheels.
l When rotating, repairing or changing your tires, check that the
wheel nuts are still tight after driving 1000 miles (1600 km).
l Be careful not to damage the aluminum wheels when using
tire chains.
l Use only Toyota genuine balance weights or equivalent and a
plastic or rubber hammer when balancing your wheels.

280 4-3. Do-it-yourself maintenance
nWhen replacing wheels
The wheels of your Toyota, except for the compact spare tire, are
equipped with tire pressure warning valves and transmitters 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 a nd transmitters must be installed.
( → P. 270)
CAUTION
nWhen replacing wheels
lDo not use wheels that are a different size from those recommended in
the Owner’s Manual, as this may re sult in loss of handling control.
lNever 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
nReplacing tire pressure warning valves and transmitters
lBecause 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.
lEnsure that only genuine Toyota wheels are used on your vehicle.
Tire pressure warning valves and transmitters may not work properly
with non-genuine wheels.
