MAINTENANCE
• 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,
2
0.3-0.4 kgf/cm
) higher than checked when cold.
• At least once a month or before long trips, use a gauge to measure the
pressure in all tires. Even tires in good condition can lose 1-2 psi (10-20
2
kPa, 0.1-0.2 kgf/cm
) per month.
Inspection Guidelines
n
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
n
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.
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
the owner's manual regarding tire inflation and maintenance.
Tire and Loading Information Label
n
The label attached to the driver's doorjamb provides necessary tire and
loading information.
1. The number of people your vehicle can carry.
2. The total weight your vehicle can carry. Do not exceed this weight.
3. The original tire sizes for front, rear, and spare.
4. The proper cold tire pressure for front, rear, and spare.
Tire and Wheel Replacement
n
Replace your tires with radials of the same size, load range, speed rating,
and maximum cold tires pressure rating (as shown on the tires' 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.
