INSTALLATION
11 1
WARNING
Only install original equipment (stock) tire valves and
valve caps. A valve or valve and cap combination that is
too long may interfere with (strike) adjacent components,
damage the valve and cause rapid tire deflation. Rapid
tire deflation could cause loss of control. These events
could result in death or serious injury.
11 1
WARNING
Aftermarket valve caps that are heavier than the stock
cap may have clearance at slow speeds; but, at high
speed the valve/cap will be moved outward by centrifugal
force. This outward movement could cause the valve/cap
to strike the adjacent components, damage the valve and
cause rapid tire deflation. Rapid tire deflation could
cause loss of control. These events could result in death
or serious injury.
1. Damaged or leaking valve stems must be replaced.
Place rubber grommet on valve stem with shoulder in
recess of the valve stem head.
2. Install and tighten nut to 42-44 in-lbs (4.7-5.0 Nm).
3. Thoroughly lubricate rim flanges and both beads of tire
with tire lubricant.
4. See Figure 2-17. Starting at the valve stem, start first
bead into the rim well using a bead breaker machine. If
no machine is available, work bead on as far as possible
by hand. Use a tire tool to pry the remaining bead over
rim flange.
5. Start 180° from valve stem hole and place second bead
on rim. Work bead onto rim with tire tools, working
toward valve in both directions.

WARNING
Do not inflate over 40 psi (275 kPa) to seat the beads.
Inflating the tire beyond 40 psi (275 kPa) to seat the
beads can cause the tire rim assembly to burst with force
sufficient to cause death or serious injury. If the beads
fail to seat to 40 psi (275 kPa), deflate and relubricate the
bead and rim and reinflate to seat the beads, but do not
exceed 40 psi (275 kPa).
6. Apply air to stem to seat beads on rim. It may be neces-
sary to use a TIRE BEAD EXPANDER (Part No. HD-
28700) on the tire until beads seal on rim.
Checking Tire Lateral Runout
1. See Figure 2-18. Turn wheel on axle and measure
amount of displacement from a fixed point to tire side-
wall.
2. Tire tread lateral runout should be no more than 0.080
in. (2.03 mm). If runout is more than 0.080 in. (2.03 mm),
remove tire from rim.
3. Check rim bead side runout. See
RIM RUNOUT. Replace rims not meeting specifications.
4. Install tire and check again for tire tread lateral runout.

Checking Tire Radial Runout
1. See Figure 2-19. Turn wheel on axle and measure tread
radial runout.
2. Tire tread radial runout should not be greater than 0.060
in. (1.52 mm). If runout exceeds specification, remove
tire from rim.
3. Check rim bead runout. See
RUNOUT. Replace rims not meeting specifications.
4. Install tire and check tire tread radial runout again.
