Tire Chains (Traction Devices)

Use of traction devices require sufficient tire-to-
body clearance. Follow these recommendations
to guard against damage.
• Traction device must be of proper size for the
tire, as recommended by the traction device
manufacturer.
• Install on Rear Tires Only
• Due to limited clearance, RUD-GRIP 4X4 or
Equivalent is recommended
295/45ZR20 tires.
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.
CAUTION!
To avoid damage to your vehicle or tires,
observe the following precautions:
• Because of restricted traction device clear-
ance between tires and other suspension
components, it is important that only trac-
tion devices in good condition are used.
Broken devices can cause serious dam-
age. Stop the vehicle immediately if noise
occurs that could indicate device break-
age. Remove the damaged parts of the
device before further use.
• Install device as tightly as possible and
then retighten after driving about ½ mile
on
(0.8 km).
• 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.
CAUTION! (Continued)
• 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.

Tire Rotation Recommendations

The tires on the front and rear of your vehicle
operate at different loads and perform different
steering, handling, 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 On/Off-Road type tires. Rotation will
increase tread life, help to maintain mud, snow,
and wet traction levels, and contribute to a
smooth, quiet ride.
(Continued)
Refer to the "Service and Warranty Handbook"
for the proper maintenance intervals. More fre-
quent rotation is permissible if desired. The
reasons for any rapid or unusual wear should be
corrected prior to rotation being performed.
