5.3.2 Wheel Cleaning
Remove all rust, corrosion, dirt and other foreign material
from all metal surfaces. In particular, the bead area (tire-
to-wheel mounting surface) must be especially clean.
5.3.3 Wheel Inspection and Replacement
Check all surfaces of the wheel for rust, corrosion,
cracks, bent flanges, deep marks or gouges. Replace a
damaged, worn or cracked wheel. NEVER rework, heat,
weld or braze a wheel rim.
Inspect the valve core and stem. Replace the entire valve
if either component is damaged.
5.3.4 Installing Wheel and Tire Assembly
onto Vehicle
IMPORTANT: The wheel and tire assemblies must be
installed with the directional tread pattern “arrows” facing
in the direction of forward travel (Fig. 5–4).
1. Position wheel onto studs on wheel end of axle.
2. Install wheel lug washers.
3. Install lug nuts and tighten in an alternating pattern
(Fig. 5–5). Torque to 370 lb/ft (500 Nm).
5.3.5 Tires
A. Dismounting Tire from Wheel
B. Wheel Inspection and Replacement
Replace any tire that is worn or cut through the cords.
When replacing a tire, follow the recommendations of the
tire manufacturer.
C. Tire and Wheel Lubrication
Prior to mounting the tire on the rim, apply a suitable
lubricant to the bead-seat area of the wheel rim and tire
bead. Use a lubricant specified by the wheel and tire
manufacturers.
WARNING: Dirt and rust prevent the tire from
seating properly on the wheel, which could
result in an explosive separation. Such explo-
sions could result in severe personal injury or
death to the tire installer and to those in the
area.
WARNING: NEVER rework, heat, weld or
braze a wheel rim.
Clean and inspect the wheel rim before installing
a new tire. Verify that the wheel rim diameter
exactly matches the tire rim diameter molded
into the tire.
WARNING: Risk of serious personal injury.
When removing a tire from a wheel:
• Use safety chains, or place the wheel and
tire assembly in a safety cage when deflating
a tire or when inflating a newly mounted tire.
• Deflate tire completely before servicing.
NEVER attempt to unseat the beads of an
inflated tire.
• NEVER re-inflate a tire that has been run flat
or seriously under-inflated without removing
the tire from the wheel and checking for tire
and wheel (rim) damage.
• NEVER hit a tire or wheel rim with a hammer
or NEVER object.
• NEVER rework, heat, weld or braze a wheel
rim.
• Use the appropriate specialty tools and
equipment for mounting a tire to a wheel or
for dismounting a tire from a wheel, or have
a qualified professional perform the work.
DO NOT attempt to mount or dismount a
tire without the proper tools, training and
equipment.
WARNING: Clean and inspect the wheel rim
before installing a new tire. Verify that the wheel
rim diameter exactly matches the tire rim diam-
eter molded into the tire.
Inspect the inside of the tire for dirt, foreign
material, loose cords, cuts, penetrating objects,
and other damage. DO NOT use tires with
irreparable damage.
WARNING: Risk of serious personal injury.
Use an approved tire-mounting lubricant only.
NEVER use antifreeze, silicones or petroleum-
based lubricants.
