TIRES AND WHEELS
WARNING
Tire failure may cause loss of
vehicle control resulting in an
accident. To reduce risk of SERIOUS
INJURY or DEATH, take the
following precautions:
• Inspect your tires monthly for
proper inflation as well as wear
and damage.
• The recommended cold tire
pressure for your vehicle can be
found in this manual and on the
tire label located on the driver’s
side center pillar. Always use a
tire pressure gauge to measure
tire pressure. Tires with too
much or too little pressure wear
unevenly causing poor handling.
• Check the pressure of the spare
tire every time you check the
pressure of the other tires on
your vehicle.
• Replace tires that are worn, show
uneven wear, or are damaged.
Worn tires can cause loss of
braking effectiveness, steering
control, or traction.
• ALWAYS replace tires with the
same size, type, construction and
tread pattern as each tire that
was originally supplied with this
vehicle. Using tires and wheels
other than the recommended
sizes could cause unusual
handling characteristics, poor
vehicle control, or negatively
affect your vehicle’s Anti-Lock
Brake System (ABS) resulting in a
serious accident.
Tire Care
For proper maintenance, safety, and
maximum fuel economy, you must
always maintain recommended
tire inflation pressures and stay
within the load limits and weight
distribution recommended for your
vehicle.
OTM010024L OTM010024L
All specifications (sizes and
pressures) can be found on a label
attached to the driver’s side center
pillar.
Recommended Cold Tire
Inflation Pressures
All tire pressures (including the
spare) should be checked when the
tires are cold. “Cold tires” means the
vehicle has not been driven for at
least three hours or driven less than 1
mile (1.6 km).
Warm tires normally exceed
recommended cold tire pressures
by 4 to 6 psi (28 to 41 kPa). Do not
release air from warm tires to adjust
the pressure or the tires will be
under-inflated. For recommended
inflation pressure, refer to “Tire and
Wheels” section in chapter 2.
