Checking and Maintaining Tires

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 specifications 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, 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 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. 467

• Cracks or other damage around valve stem.

1

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 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.

Check the spare tire pressure once a month or before
long trips.

3

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.

The tire identification number (TIN) is a group of numbers and letters that look like
the example in the side column. TIN is located on the sidewall of the tire.

Cold Tire Pressure – The tire air pressure when the vehicle has been parked for at
least three hours or driven less than 1 mile (1.6 km).
Load Rating – Means the maximum load that a tire is rated to carry for a given
inflation pressure.
Maximum Inflation Pressure – The maximum tire air pressure that the tire can
hold.
Maximum Load Rating – Means the load rating for a tire at the maximum
permissible inflation pressure for that tire.
Recommended Inflation Pressure – The cold tire inflation pressure recommended
by the manufacturer.
Treadwear Indicators (TWI) – Means the projections within the principal grooves
designed to give a visual indication of the degrees of wear of the tread.

DOT Tire Quality Grading (U.S. Vehicles)

The tires on your vehicle meet all U.S. Federal Safety
Requirements. All tires are also graded for treadwear, traction,
and temperature performance according to Department of
Transportation (DOT) standards. The following explains these
gradings.

Quality grades can be found where applicable on the tire sidewall
between tread shoulder and maximum section width.

The treadwear grade is a comparative rating based on the wear
rate of the tire when tested under controlled conditions on a
specified government test course. For example, a tire graded 150
would wear one and one-half (1 1/2) times as well on the
government course as a tire graded 100. The relative performance
of tires depends upon the actual conditions of their use, however,
and may depart significantly from the norm due to variations in
driving habits, service practices and differences in road
characteristics and climate.

DOT Tire Quality Grading (U.S. Vehicles)

The traction grades, from highest to lowest, are AA, A, B, and C.
Those grades represent the tire’s ability to stop on wet pavement
as measured under controlled conditions on specified
government test surfaces of asphalt and concrete. A tire marked
C may have poor traction performance.

The temperature grades are A (the highest), B, and C,
representing the tire’s resistance to the generation of heat and its
ability to dissipate heat when tested under controlled conditions
on a specified indoor laboratory test wheel. Sustained high
temperature can cause the material of the tire to degenerate and
reduce tire life, and excessive temperature can lead to sudden tire
failure. The grade C corresponds to a level of performance which
all passenger car tires must meet under the Federal Motor Vehicle
Safety Standard No. 109. Grades B and A represent higher levels
of performance on the laboratory test wheel than the minimum
required by law.

Traction

Warning: The traction grade
assigned to this tire is based on
straight-ahead braking traction tests,
and does not include acceleration,
cornering, hydroplaning, or peak

Temperature

Warning: The temperature grade for
this tire is established for a tire that is
properly inflated and not
overloaded. Excessive speed,
underinflation, or excessive loading,
either separately or in combination,
can cause heat buildup and possible
tire failure.

Wear Indicators

Main

ce

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
that the indicator is exposed, replace the tire.
Worn out tires have poor traction on wet
roads.

Tire Service Life

The life of your tires is dependent on many factors, including driving habits, road
conditions, vehicle loading, inflation pressure, maintenance history, speed, and
environmental conditions (even when the tires are not in use).

In addition to regular inspections and inflation pressure maintenance, it is
recommended that you have annual inspections performed once the tires reach five
years old. All tires, including the spare, should be removed from service after 10
years from the date of manufacture, regardless of their condition or state of wear.

Checking Tires

High speed driving
We recommend that you do not drive faster than the
posted speed limits and conditions allow. If you drive
at sustained high speeds (over 99 mph or 160 km/h),
adjust the cold tire pressures as shown below to
avoid excessive heat build up and sudden tire failure.

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 such as the ABS and
Vehicle Stability Assist (VSA®) system 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 replace a wheel, only use TPMS specified wheels approved for your vehicle.
Make sure that the wheel’s specifications match those of the original wheels.

WARNING

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 this owner’s manual.
