CAUTION
Proper inflation is critical to save tire performance
Keep your tires properly inflated. Otherwise, the following conditions may
occur and result in an accident causing death or serious injury.
Excessive wear
Uneven wear
Poor handling
Possibility of blowouts resulting from overheated tires
Poor sealing of the tire bead
Wheel deformation and/or tire separation
A greater possibility of tire damage from road hazards
NOTICE
When inspecting and adjusting tire inflation pressure
Be sure to reinstall the tire valve caps.
Without the valve caps, dirt or moisture could get into the valve and cause
air leakage, which could result in an accident. If the caps have been lost,
replace them as soon as possible.

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.
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 inset
*.
Replacement wheels are available at any authorized Toyota
dealer or repairer, or another duly qualified and equipped profes-
sional.
*: Conventionally referred to as “offset”.
Toyota does not recommend using:
Wheels of different sizes or types
Used wheels
Bent wheels that have been straightened
Aluminum wheel precautions (if equipped)
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 balance weights or equivalent and a
plastic or rubber hammer when balancing your wheels.

CAUTION
When replacing wheels
Do not use wheels that are a different size from those recommended in the
Owner’s Manual, as this may result in loss of handling control.
Never use an inner tube in a leaking wheel which is designed for a tube-
less 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 end facing inward.
