Checking Tires
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 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 hazard,
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, including the spare. 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 your dealer check the wheel alignment. •
Excessive tread wear. •

Checking Tires
Measure the air pressure when tires are cold. This
means the vehicle has been parked 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 mush
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.
WARNING
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
manual regarding tire inflation and
maintenance.
