WHEEL AND TIRE ASSEMBLY REPLACEMENT

WARNING: Always take the wheel to an authorized
service center for proper servicing. Use 16.5 inch diam-
eter tires only. Mismatching tire and rim diameters is
dangerous. A mismatched tire and rim assembly may
explode and can result in serious injury or death.

WARNING: Put transmission into the PARK position,
apply parking brake, and chock opposite wheel before
removing wheel. Avoid removing any wheel when vehi-
cle is on sloping terrain. Personal injury or damage to
equipment may result. Remove only the inner group of
lug nuts when removing a wheel from the vehicle. Re-
moving the outer nuts which hold the rim together
while the assembly is inflated could result in serious in-
jury or death.

WARNING: Never mix tires of different size or tread
design. Never mix bias and radial construction tires.
Mixing tire types will adversely affect road handling
and can lead to loss of vehicle control, and could result
in serious injury or death.

NOTE:

Always depress both CTIS quick-disconnect valve

tabs on each axle set to prevent air loss from the other tire.

NOTE:

Any procedure requiring removal of lug nuts and/or

wheel-half nuts on two-piece steel wheels will first require re-
moval of the plastic nut covers. The covers pull straight off of
the lug nuts and are removed from the wheel-half nuts by turn-
ing counterclockwise.

Removal

NOTE:

On vehicles equipped with Central Tire Inflation Sys-

tem (CTIS), mark the wheel mounting studs for installation po-
sition, then perform steps 1 and 2.

Remove CTIS hose shield.

Remove tube and quick-disconnect valve from spindle.

Loosen, but do not remove, lug nuts (Figure 6-1).

Raise and support corner of vehicle.

Remove lug nuts and wheel from geared hub spindle.

Replacement

Installation

NOTE:

The Wrangler GS-A, 37 X 12.50R16.5 LT touring ra-

dial tire has an asymmetrical/directional tread design. The
heavier, stiffer tread on the outside shoulder of the tire must
face outward when being installed. Before installing on a
wheel, inspect sidewall of tire and ensure SIDE FACING
OUTWARDS imprint is facing outward (Figure 6-2).

NOTE:

Install lug nuts with fingers to full engagement. If nuts

resist finger tightening examine studs and nuts for damage and
replace if damaged.

Position wheel on geared hub spindle according to marks
on mounting studs and attach with lug nuts (Figure 6-1).

Figure 6-2: Side Facing Outwards Location

Remove support and lower corner of vehicle.

Two-piece wheel lugnut torque is 110 lb-ft (149 N•m).
Use tightening sequence shown (Figure 6-3).

Figure 6-3: Lug Nut Tightening Sequence

CAUTION:

Do not allow pipe thread sealant into air system.

Sealant will damage CTIS components and inhibit the CTIS
operation.

NOTE:

Perform steps 4 and 5 for vehicles equipped with

CTIS.

Install CTIS quick-connect valve and tube on spindle.

Install CTIS hose shield.

TIRE, TWO-PIECE WHEEL, AND RUNFLAT
REPLACEMENT

WARNING: Do not use tire machine. Personal injury
or damage to equipment may result.

CAUTION:

It is not recommended mixing one-piece wheel

runflat assemblies and two-piece take-a-part runflat wheel as-
semblies on the same vehicle. Runflat profiles are different be-
tween the two types of wheel assemblies.

CAUTION:

Do not mix two piece take-apart wheel compo-

nents from previous model year vehicles with present produc-
tion parts. Many features are not the same between the two
wheel styles and will not fit together correctly. Present produc-
tion wheel halves can be identified by a hole between two of the
wheel half studs on both halves. These holes must be aligned
when assembling the wheel halves.

Removal and Disassembly

If the vehicle is equipped with a Central Tire Inflation Sys-
tem (CTIS), perform steps a through d:

Release the quick disconnect fitting located in the
center of the geared hub spindle on all four wheels.

Remove the hose shield and lay aside.
