Tire Information
To safely operate your vehicle, your tires must be of the proper type and size, in
good condition with adequate tread, and properly inflated.
Inflation Guidelines
• Properly inflated tires provide the best combination of handling, tread life, and
comfort. Refer to the driver’s doorjamb label or the specifications (see page
138) for the specified pressure.
• Underinflated tires wear unevenly, adversely affect handling and fuel economy,
and are more likely to fail from overheating.
• Overinflated tires make your vehicle ride harshly, are more prone to road
hazards, and wear unevenly.
• Every day before you drive, look at each of the tires. If one looks lower than the
others, check the pressure with a tire gauge.
• Measure the air pressure when tires are cold. This means the vehicle has been
parked for at least 3 hours, or driven less than 1 mile (1.6 km). If necessary, add
or release air until the specified pressure is reached. If checked when hot, tire
pressure can be as much as 4-6 psi (30-40 kPa, 0.3-0.5 kgf/cm
2
) higher than
checked when cold.
• At least once a month or before long trips, use a gauge to measure the pressure
in all tires, including the spare. Even tires in good condition can lose 1-2 psi
(10-20 kPa, 0.1-0.2 kgf/cm
2
) per month.
Inspection Guidelines
Every time you inflate the tires, check for the following:
• Any damage to tires, including bumps, bulges, cuts, splits, or cracks in the side
or tread. Remove any foreign objects and inspect for air leaks. Replace tires if
you see fabric or cord.
• Uneven or excessive tread wear. Have a dealer check the wheel alignment.
• Cracks or other damage around the valve stems.
Wear Indicators
The groove where the wear indicator is located is 1/16
inch (1.6 mm) shallower than elsewhere on the tire. If
the tread has worn so low that the indicator is exposed,
replace the tire. Worn out tires have poor traction on
wet roads.

Tire and Loading Information Label
The label attached to the driver’s doorjamb provides necessary tire and
loading information.
Using tires that are excessively worn or improperly inflated can cause
a crash in which you can be seriously hurt or killed.
Follow all instructions in this owner’s guide regarding tire inflation
and maintenance.

Tire and Wheel Replacement
Replace your tires with radials of the same size, load range, speed rating, and
maximum cold tire pressure rating (as shown on the tire’s sidewall). Using
tires of a different size or construction can cause certain vehicle systems to
work incorrectly. It is best to replace all four tires at the same time. If that isn’t
possible, replace the front or rear tires in pairs.
If you change or replace a wheel, make sure that the wheel’s specifications match
those of the original wheels. Only use TPMS-specified wheels approved for your
vehicle.
Installing improper tires on your vehicle can affect handling and stability.
This can cause a crash in which you can be seriously hurt or killed.
Always use the size and type of tires recommended in the Owner’s Manual.
