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 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. 493

• 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.

Measure 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.

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)

Main

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 
traction characteristics.

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

tenan

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 118 mph or 190 
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 the ABS and vehicle stability assist (VSA®) 
and SH-AWD® 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.

Make sure that the wheel’s specifications match those of the original wheels.

If you replace a wheel, only use TPMS specified wheels approved for your vehicle.

Winter Tires

If driving on snowy or frozen roads, mount all season marked M+S tires, snow tires, 
or tire chains; reduce speed; and maintain sufficient distance between vehicles when 
driving.

Be particularly careful when operating the steering wheel or brakes to prevent 
skidding.

Use tire chains, snow tires, or all season tires when necessary or according to the law.

When mounting, refer to the following points.

For winter tires:
• Select the size and load ranges that are the same as the original tires.
• Mount the tires to all four wheels.
For tire chains:
• Install them on the front tires only.
• Because your vehicle has limited tire clearance, we strongly recommend using the 

chains listed below:

• Follow the chain manufacturer’s instruction when installing. Mount them as 

tightly as you can.

• Check that the chains do not touch the brake lines or suspension.
• Drive slowly.

Cable-type: SCC Radial Chain SC1040

NOTICE

Traction devices that are the wrong size or improperly 
installed can damage your vehicle’s brake lines, 
suspension, body, and wheels. Stop driving if they are 
hitting any part of the vehicle.

When tire chains are mounted, follow the chain 
manufacturer’s instructions regarding vehicle 
operational limits.

If your vehicle is equipped with summer tires, be 
aware that these tires are not designed for winter 
driving conditions. For more information, contact a 
dealer.

WARNING

Using the wrong chains, or not properly 
installing chains, can damage the brake 
lines and cause a crash in which you can be 
seriously injured or killed.

Follow all instructions in this owner’s 
manual regarding the selection and use of 
tire chains.

Dust off the vehicle body after you drive.
Regularly inspect your vehicle for scratches on painted surfaces. A scratch on a 
painted surface can result in body rust. If you find a scratch, promptly repair it.

Wash the vehicle regularly. Wash more frequently when driving in the following 
conditions:
• If driving on roads with road salt.
• If driving in coastal areas.
• If tar, soot, bird droppings, insects, or tree sap are stuck to painted surfaces.

• Make sure to follow the instructions indicated on the automated car wash.
• Fold in the door mirrors.
• Turn off the automatic intermittent wipers.

• Keep sufficient distance between the cleaning nozzle and the vehicle body.
• Take particular care around the windows. Standing too close may cause water to
