Axles, Wheels and Tires
b. Wheel Inspection and Replacement
WARNING:
repaired or mis-matched wheels and tires, or
dirt and rust prevent the tire from seating prop-
erly on the wheel, which could result in an
explosive separation. Such explosions could
result in death or severe personal injury.
• 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.
• Inspect the inside of the tire for dirt, for-
eign material, loose cords, cuts, pene-
trating objects, and other damage. DO
NOT use tires with irreparable damage.
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
WARNING:
personal injury. Use an approved tire-mounting
lubricant only. NEVER use anti-freeze, sili-
cones or petroleum-based lubricants.
Prior to mounting the tire on the rim, apply a suitable lu-
bricant to the bead-seat area of the wheel rim and tire bead.
Use a lubricant specified by the wheel and tire manufacturers.
d. Mounting Tire onto Wheel
WARNING:
personal injury. Using incorrect tire mounting
methods, or using damaged or dirty compo-
nents could result in an explosive separation.
When mounting a tire onto a wheel, follow the
"Wheel Mounting Instructions" box below.
1. Read, understand and follow the above warning
message.

Wheel Mounting Instructions:
• Use the appropriate specialty tools and equip-
ment for mounting a tire to a wheel or for dis-
mounting 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.
• Clean and inspect the wheel rim before install-
ing a new tire. Verify that the wheel rim diameter
exactly matches the tire rim diameter 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 irrep-
arable damage.
• Use an approved tire-mounting lubricant only.
NEVER use anti-freeze, silicones or petroleum-
based lubricants.
• 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.
• Inflate the tire to the cold-operating pressure
recommended by the tire manufacturer.
2. Clean, inspect and replace the wheel if necessary.
DO NOT use a damaged or cracked wheel.
3. Orient the tire in the direction of forward travel required.
4. Lubricate the inner tire and rim beads with an
approved tire-mounting lubricant only. NEVER use
anti-freeze, silicones or petroleum-based lubricants.
5. Push the inner bead of the tire over and around as
much of the wheel rim as possible. Use tire irons or a
suitable, commercially available pneumatic tire
installation machine to work the bead completely
over the rim in small increments. Be careful not to
damage the bead.
6. Lubricate the outer tire and rim beads with an
approved tire-mounting lubricant.
7. Starting opposite the valve hole, use tire irons to
work the outer tire bead over the wheel rim. Work
the bead completely over the rim in small increments
(DO NOT damage the bead).
