the original equipment tire and reinstall on

Limited Use Spare — If Equipped
The limited use spare tire is for temporary
emergency use only. This tire is identified by
a label located on the limited use spare
wheel. This label contains the driving limita-
tions for this spare. This tire may look like the
original equipped tire on the front or rear axle
of your vehicle, but it is not. Installation of
this limited use spare tire affects vehicle
handling. Since it is not the same as your
original equipment tire, replace (or repair)
the original equipment tire and reinstall on
the vehicle at the first opportunity.
WARNING!
Limited use spares are for emergency use
only. Installation of this limited use spare
tire affects vehicle handling. With this tire,
do not drive more than the speed listed on
the limited use spare wheel. Keep inflated
to the cold tire inflation pressures listed on
WARNING!

located on the driver’s side B-Pillar or the
rear edge of the driver’s side door. Replace
(or repair) the original equipment tire at
the first opportunity and reinstall it on your
vehicle. Failure to do so could result in loss
of vehicle control.
Wheel And Wheel Trim Care
All wheels and wheel trim, especially alumi-
num and chrome plated wheels, should be
cleaned regularly using mild (neutral Ph)
soap and water to maintain their luster and to
prevent corrosion. Wash wheels with the
same soap solution recommended for the
body of the vehicle.
Your wheels are susceptible to deterioration
caused by salt, sodium chloride, magnesium
chloride, calcium chloride, etc., and other
road chemicals used to melt ice or control
dust on dirt roads. Use a soft cloth or sponge
and mild soap to wipe away promptly. Do notuse harsh chemicals or a stiff brush. They can
damage the wheel’s protective coating that
helps keep them from corroding and
tarnishing.
CAUTION!
Avoid products or automatic car washes
that use acidic solutions or strong alkaline
additives or harsh brushes. Many aftermar-
ket wheel cleaners and automatic car
washes may damage the wheel's protective
finish. Such damage is not covered by the
New Vehicle Limited Warranty. Only car
wash soap, Mopar Wheel Cleaner or
equivalent is recommended.
When cleaning extremely dirty wheels includ-
ing excessive brake dust, care must be taken
in the selection of tire and wheel cleaning
chemicals and equipment to prevent damage
to the wheels. Mopar Wheel Treatment or
Mopar Chrome Cleaner or their equivalent is
recommended or select a non-abrasive, non-
acidic cleaner for aluminum or chrome
wheels.
271

CAUTION!
Do not use scouring pads, steel wool, a
bristle brush, metal polishes or oven
cleaner. These products may damage the
wheel's protective finish. Such damage is
not covered by the New Vehicle Limited
Warranty. Only car wash soap, Mopar
Wheel Cleaner or equivalent is recom-
mended.
NOTE:
If you intend parking or storing your vehicle
for an extended period after cleaning the
wheels with wheel cleaner, drive your vehicle
and apply the brakes to remove the water
droplets from the brake components. This
activity will remove the red rust on the brake
rotors and prevent vehicle vibration when
braking. Dark Vapor Chrome, Black Satin Chrome, or Low
Gloss Clear Coat WheelsCAUTION!
If your vehicle is equipped with these
specialty wheels, DO NOT USE wheel
cleaners, abrasives, or polishing com-
pounds. They will permanently damage
this finish and such damage is not covered
by the New Vehicle Limited Warranty.
HAND WASH ONLY USING MILD SOAP
AND WATER WITH A SOFT CLOTH. Used
on a regular basis; this is all that is re-
quired to maintain this finish.

UNIFORM TIRE QUALITY GRADES
The following tire grading categories
were established by the National High-
way Traffic Safety Administration. Thespecific grade rating assigned by the
tire's manufacturer in each category is
shown on the sidewall of the tires on
your vehicle.
All passenger vehicle tires must con-
form to Federal safety requirements in
addition to these grades.
Treadwear
The Treadwear grade is a comparative
rating, based on the wear rate of the
tire when tested under controlled con-
ditions on a specified government test
course. For example, a tire graded
150 would wear one and one-half
times as well on the government
course as a tire graded 100. The rela-
tive performance of tires depends
upon the actual conditions of their
use, however, and may depart signifi-
cantly from the norm due to variations
in driving habits, service practices,
and differences in road characteristics
and climate.
SERVICING AND MAINTENANCE
272

Traction Grades
The Traction grades, from highest to
lowest, are AA, A, B, and C. These
grades represent the tire's ability to
stop on wet pavement, as measured
under controlled conditions on speci-
fied government test surfaces of as-
phalt and concrete. A tire marked C
may have poor traction performance.
WARNING!
The traction grade assigned to this
tire is based on straight-ahead brak-
ing traction tests, and does not in-
clude acceleration, cornering, hy-
droplaning, or peak traction
characteristics.
Temperature Grades
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 condi-
tions 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 pas-
senger vehicle tires must meet under
the Federal Motor Vehicle Safety Stan-
dard No. 109. Grades B and A repre-
sent higher levels of performance on
the laboratory test wheel, than the
minimum required by law.
WARNING!
The temperature grade for this tire is
established for a tire that is properly
inflated and not overloaded. Exces-
sive speed, under-inflation, or ex-
cessive loading, either separately or
in combination, can cause heat
buildup and possible tire failure.

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 lug
nuts/bolts should be torqued using a properly
calibrated torque wrench using a high quality
six sided (hex) deep wall socket.
Torque Specifications
All wheel nuts should be tightened occasion-
ally to eliminate the possibility of wheel studs
being sheared or the bolt holes in the wheels
becoming elongated. This is especially im-
portant during the first few hundred miles/
kilometers of operation to allow the wheel
nuts to become properly set. All wheel nuts
should first be firmly seated against the
wheel. The wheel nuts should then be tight-
ened to recommended torque. Tighten the
wheel nuts to final torque in increments.
Progress around the bolt circle, tightening
the wheel nut opposite to the wheel nut justpreviously tightened until final torque is
achieved. Ensure that the socket is fully en-
gaged on the lug nut/bolt (do not insert it
halfway).

lowing chart:

8-Stud — Dual Rear Wheels
• Dual wheels are flat-mounted and center-
piloted. The lug nuts are a two-piece as-
sembly. When the tires are being rotated or
replaced, clean these lug nuts and add two
drops of oil at the interface between the hex
and the washer. • Slots in the wheels will assist in properly
orienting the inner and outer wheels. Align
these slots when assembling the wheels for
best access to the tire valve on the inner
wheel. The tires of both dual wheels must
be completely off the ground when tighten-
ing, to ensure wheel centering and maxi-
mum wheel clamping.
Oil Interface LocationTECHNICAL SPECIFICATIONS

• Dual wheel models require a special heavy-duty lug nut tightening adapter (included
with the vehicle) to correctly tighten the lug
nuts. Also, when it is necessary to remove
and install dual rear wheels, use a proper
vehicle lifting device.
NOTE:
When installing a spare tire as part of a dual
rear wheel end combination, the tire diam-
eter of the two individual tires must be com-
pared. If there is a significant difference, the
larger tire should be installed in a front loca-
tion. The correct direction of rotation for dual
tire installations must also be observed. These dual rear wheels should be tightened as
follows:
1. Tighten the wheel nuts in the numbered
sequence to a snug fit. 2. Retighten the wheel nuts in the same
sequence to the torques listed in the
table. Go through the sequence a second
time to verify that specific torque has
been achieved. Retighten to specifica-
tions at 100 miles (160 km) and after
500 miles (800 km).
• It is recommended that wheel stud nuts be kept torqued to specifications at all times.
Torque wheel stud nuts to specifications at
each lubrication interval.
