SERVICING AND MAINTENANCE237
Summer tires do not contain the all season
designation or mountain/snowflake symbol on the
tire sidewall. Use Summer tires only in sets of four;
failure to do so may adversely affect the safety and
handling of your vehicle.
Snow Tires
Some areas of the country require the use of snow
tires during the Winter. Snow tires can be identified
by a “mountain/snowflake” symbol on the tire
sidewall.
If you need snow tires, select tires equivalent
in size and type to the original equipment
tires. Use snow tires only in sets of four;
failure to do so may adversely affect the
safety and handling of your vehicle.

Snow tires generally have lower speed ratings than
what was originally equipped with your vehicle and
should not be operated at sustained speeds over
75 mph (120 km/h). For speeds above 75 mph (120 km/h) refer to original equipment or an
authorized tire dealer for recommended safe
operating speeds, loading and cold tire inflation
pressures.

While studded tires improve performance on ice, skid
and traction capability on wet or dry surfaces may be
poorer than that of non-studded tires. Some states
prohibit studded tires; therefore, local laws should be
checked before using these tire types.

SPARE TIRES — IF EQUIPPED
NOTE:For vehicles equipped with Tire Service Kit instead
of a spare tire, please refer to “Tire Service Kit” in
“In Case Of Emergency” for further information.
For restrictions when towing with a spare tire
designated for temporary emergency use
Ú
page 114.
Spare Tire Matching Original Equipped Tire
And Wheel — If Equipped

Your vehicle may be equipped with a spare tire and
wheel equivalent in look and function to the original
equipment tire and wheel found on the front or rear
axle of your vehicle. This spare tire may be used in the
tire rotation for your vehicle. If your vehicle has this
option, refer to an authorized tire dealer for the
recommended tire rotation pattern.

NOTE:This spare tire may not have a TPMS sensor.
Compact Spare Tire — If Equipped
The compact spare is for temporary emergency
use only. You can identify if your vehicle is
equipped with a compact spare by looking at the
spare tire description on the Tire and Loading
Information Placard located on the driver’s side
door opening or on the sidewall of the tire.
Compact spare tire descriptions begin with the
letter “T” or “S” preceding the size designation.
Example: T145/80D18 103M.
T, S = Temporary Spare Tire
Since this tire has limited tread life, the original
equipment tire should be repaired (or replaced)
and reinstalled on your vehicle at the first
opportunity.
WARNING!

Do not use Summer tires in snow/ice conditions. You
could lose vehicle control, resulting in severe injury
or death. Driving too fast for conditions also creates
the possibility of loss of vehicle control.

CAUTION!

Because of the reduced ground clearance, do not
take your vehicle through an automatic car wash
with a compact or limited use temporary spare
installed. Damage to the vehicle may result.

SNOW TRACTION DEVICES
Use of traction devices require sufficient tire-to-body clearance. Due to limited clearance the following traction devices are recommended. Follow these
recommendations to guard against damage.
Snow traction device must be of proper size for the tire, as recommended by the traction device manufacturer.
No other tire sizes are recommended for use with a tire chain or traction device.
Please see the following table for the recommended tire size, axle and snow traction device:
FWD
Trim Level Axle Tire/Wheel Size Snow Traction Device (maximum projection beyond tire profile or equivalent)
All
FrontLT225/75R16E
225/75R16C Quality Chain Corp Light Truck Highway Service (Non-Cam) tire chain or equivalent is
recommended.
WARNING!
Using tires of different size and type (M+S, Snow) between front and rear axles can cause unpredictable handling. You could lose control and have a collision.

TIRE ROTATION RECOMMENDATIONS
The tires on the front and rear of your vehicle
operate at different loads and perform different
steering, driving, and braking functions. For these
reasons, they wear at unequal rates.

These effects can be reduced by timely rotation of tires.
The benefits of rotation are especially worthwhile with
aggressive tread designs such as those on all season
type tires. Rotation will increase tread life, help to
maintain mud, snow and wet traction levels, and
contribute to a smooth, quiet ride.
Refer to the Maintenance Plan for the proper
maintenance intervals Ú
page 199. The reasons
for any rapid or unusual wear should be corrected
prior to rotation being performed.
The suggested rotation method is the “forward
cross” shown in the following diagram. This
rotation pattern does not apply to some directional
tires that must not be reversed.

Tire Rotation (Forward Cross)

CAUTION!
To avoid damage to your vehicle or tires, observe
the following precautions:

Because of restricted traction device clearance
between tires and other suspension components,
it is important that only traction devices in good
condition are used. Broken devices can cause
serious damage. Stop the vehicle immediately if
noise occurs that could indicate device breakage.
Remove the damaged parts of the device before
further use.

Install device as tightly as possible and then
retighten after driving about ½ mile (0.8 km).
Autosock traction devices do not require
retightening.
Do not exceed 30 mph (48 km/h).
Drive cautiously and avoid severe turns and
large bumps, especially with a loaded vehicle.
Do not drive for a prolonged period on dry
pavement.
Observe the traction device manufacturer’s
instructions on the method of installation,
operating speed, and conditions for use.
Always use the suggested operating speed of
the device manufacturer’s if it is less than
30 mph (48 km/h).
Do not use traction devices on a compact
spare tire.
CAUTION!
