MaintenanceTOC
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
houlder 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 practi ces and differences in road characteristics and climate.
For example:
Treadwear 200
Traction AA
Temperature A
All passenger car tires must conform to Federal
Safety Requirements in addition to these grades.

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 asphat 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 heate when
te sted 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.Warning: The traction grade assigned to this tire is
abased on straight-ahead braking traction tests,
and does not include acceleration, cornering,
hydroplaning, or peak traction characteristics.
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.

uu Checking and Maintaining Tires u Wear Indicators



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 ma ny factors, including driving habits, road
conditions, vehicle loading, inflation pr essure, maintenance history, speed, and
environmental conditions (even wh en the tires are not in use).
In addition to regular in spections and inflation pressure maintenance, it is
recommended that you have annual inspections performed once the tires reach five
years old. All tires, including a spare
*, should be removed from service after 10 years
from the date of manufacture, regardless of their condition or state of wear.

uu Checking and Maintaining Tires u Tire and Wheel Replacement


Tire and Wheel Replacement
Replace your tires with ra dials 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 ®)
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.
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.1 Tire and Wheel Replacement
3 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.

uu Checking and Maintaining Tires u Winter Tires


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 distan ce 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 instru ction 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 SC1034
1Winter Tires
NOTICETraction devices that are th e 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.
3 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.
