439Maintenance
Checking and Maintaining TiresChecking TiresTo 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 specification’s page 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.
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 to 2 psi (10 to 20 kPa, 0.1 to 0.2 kgf/cm
2)
per month.
■Inspection guidelines
Every time you check inflation, also examine the tires and valve stems.
Look for:
• Bumps or bulges on the side or in the tread. Replace the tire if you find any cuts,
splits, or cracks in the side of the tire. Replace it if you see fabric or cord.
• Remove any foreign objects and inspect for air leaks.
• Uneven tread wear. Have a dealer check the wheel alignment.
• Excessive tread wear.2 Wear Indicators P. 444
•Cracks or other damage around valve stem.
1Checking Tires
Measure the air pressure when tires are cold. This
means the vehicle has been par ked for at least three
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 – 0.4 kgf/cm
2) higher than
if checked when cold.
Have a dealer check the tires if you feel a consistent
vibration while driving. New tires and any that have
been removed and reinstalled should be properly
balanced.
Measure the spare tire pressure once a month or
before long trips.

WARNING
Using tires that are excessively worn or
improperly inflated can cause a crash in
which you can be seri ously hurt or killed.
Follow all instruc tions in this owner’s
manual regarding tire inflation and
maintenance.Vehicles with optional spare tire kit
