2018 JEEP WRANGLER UNLIMITED spare wheel

• Due to limited clearance, the following
traction devices are recommended:
• Original equipment 255/70R18 and
LT255/70R17 tire sizes are not chainable.
• The use of S-class snow chains is permitted
with the use of 245/75R17 tires on size 17
x 7.5 ET44.45 wheels.
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
clearance between tires and other sus-
pension components, it is important
that only traction devices in good condi-
tion are used. Broken devices can cause
serious damage. Stop the vehicle imme-
diately if noise occurs that could indi-
CAUTION!
cate device breakage. Remove the dam-
aged parts of the device before further
use.
• Install device as tightly as possible and
then retighten after driving about ½ mile
(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.
• Observe the traction device manufactur-
er’s instructions on the method of instal-
lation, operating speed, and conditions
for use. Always use the suggested oper-
ating speed of the device manufacturer’s
if it is less than 30 mph (48 km/h).
• Do not use traction devices on a com-
pact spare tire.
Tire Rotation Recommendations
The tires on the front and rear of your vehicle
operate at different loads and perform differ-
ent steering, handling, and braking func-
tions. For these reasons, they wear at unequal
rates.
These effects can be reduced by timely rota-
tion 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.
Refer to the “Maintenance Plan” for the
proper maintenance intervals. The reasons
for any rapid or unusual wear should be
corrected prior to rotation being performed.
The suggested rotation method is the
“rearward-cross” shown in the following
diagram.

VEHICLE IDENTIFICATION
NUMBER
The Vehicle Identification Number (VIN) is
found on the left front corner of the A pillar,

the windshield. This number also appears
underbody, on the right side of the frame rail
near the center of the vehicle, as well as on
the Automobile Information Disclosure Label
affixed to a window on your vehicle. Save this
label for a convenient record of your vehicle
identification number and optional equip-
ment.
The VIN is also stamped on either right or left
hand side of the engine block.NOTE:
It is illegal to remove or alter the VIN plate.
WHEEL AND TIRE TORQUE
SPECIFICATIONS
Proper lug nut/bolt torque is very important to
ensure that the wheel is properly mounted to
the vehicle. Any time a wheel has been re-
moved and reinstalled on the vehicle, the lugnuts/bolts should be torqued using a properly
calibrated torque wrench using a high quality
six sided (hex) deep wall socket.
