shoulders or sidewalls. In addition, never attempt to
repair any tire that has sustained the following damage:
• Bulges or blisters
• Ply separations
• Broken, cut, or cracked beads
• Fabric cracks or cuts
•Tires worn to the fabric or if wear indicators are
visible
• Punctures larger than 1/4 inch (6 mm) in diameter
Externally applied repair plugs, blowout patches, and
aerosol sealants should be considered as emergency-type
repairs only. Tires repaired in this fashion should not be
driven at speeds over 40 mph (64 km/h) or for more than
75 miles (121 km) before permanent repair is made.
TIRE ROTATION
To equalize wear, tires should be rotated at the inter
vals specified in the Mechanical Maintenance Schedule.
The first rotation is the most important in setting the
stage for even tread wear. After rotation, adjust tire
inflation pressures to the levels recommended in the
Tire Inflation Pressure Chart.
Radial tires are not rotated in the same manner as
conventional tires. Conventional tires are rotated in a
crossing pattern. Radial tires are rotated on the same
side, front-to-rear (fig. 2H-7).

RADIAL, WIDE TREAD AND SNOW TIRE APPLICATIONS
Radial, wide tread, mud and snow, or conventional
tires must be installed in complete sets only. This is
especially important on vehicles with Quadra-Trac. Dif
ferent tire types must not be intermixed at any time.
CAUTION: Tires installed on Jeep four-wheel drive
vehicles must all be of equal circumference to maintain
satisfactory operation. They must also be the same size,
tread pattern, make, construction, and inflation pres
sure. Intermixing tires of different size or construction
will cause unusual handling, noisy operation, and accel
erated wear of driveline components.
Wide tread tires must be installed in complete sets

and only when there is adequate clearance for the tire in
the wheel well. Refer to the Tire Inflation Pressure
Chart for tire sizes allowable on each model.
Radial tires must never be intermixed with bias-ply or
bias-belted tires on any vehicle. Intermixing these tires
will produce an adverse effect on vehicle handling and
cornering stability. In an emergency situation, tires may
be intermixed but only for the duration of the emer
gency and only if vehicle speed is kept below 40 mph (64
km/h).
Mud and snow tires must not be intermixed with
conventional tread tires on any vehicle. These tires must
also be of the same size, tread pattern, make, construc
tion, and inflation pressure. In addition, never mix bias-
ply or bias-belted snow tires with radial-ply mud or
snow tires.
POLYSPARETIRE
The Polyspare lightweight spare tire is optionally
available on CJ and Scrambler models and standard
equipment on Cherokee and Wagoneer models and J-10
trucks is designed for emergency use only. Operation of
the tire at speeds over 50 mph (80 km/h) and travel in
excess of 100 continuous miles (160 km) is not
recommended.
The Polyspare tire is mounted on a standard type 15 x
6-inch steel wheel. Correct inflation pressure is 32 psi
(221 kPa) and the tire can be inflated with conventional
inflation equipment. Installation and removal of Poly
spare does not require special tools and the anticipated
tread life is approximately 3,000 miles (4 800 km).
WHEELS
The standard equipment wheels used on Jeep vehicles
are safety rim, drop center, J-type wheels of all-steel
construction. Optional wheels include chrome-plated
styled steel wheels, wide rim spoke-type steel wheels,
and forged aluminum wheels.
Steel wheels are of two-piece construction consisting
of a rim and center section (spider). The two sections are
welded together to form a seamless, air-tight assembly.
WHEEL MAINTENANCE AND CONDITION
Wheel condition should be checked frequently. Re
place any wheel that is cracked, bent, severely dented,
has excessive runout, or has broken welds. The tire
inflation valve should also be inspected frequently for
wear, leaks, cuts, or looseness and should be replaced if
damaged or worn.
Clean all wheels with a mild soap and water solution
only and rinse thoroughly with water. Never use abra
sive or caustic materials, especially on aluminum or
chrome plated wheels as the surface will be etched or the
plating severely damaged. After cleaning aluminum or
chrome plated wheels, apply a coating of protective wax
to preserve the finish and lustre.
