WARNING Use of a volatile or flammable material, such as ether or
gasoline, as an aid to seating the tire beads on the wheel can lead to an
uncontrolled pressure build-up in the tire and may result in an explosion.
Explosive separation of the tire and wheel can occur while seating beads
in this manner, while adding air to the tire on or off the vehicle, or later on
the road. Loss of vehicle control can result, which can cause serious injury
or death.
Use only approved mechanical or pneumatic bead seating devices.

Mounting
tubeless tires
3-2
NOTICE: Not all tire
mounting/demounting
machines work alike. Be sure
to read the operating
or instruction manual for your
particular machine before
attempting to mount
or demount tires.
NOTICE: Do not exceed
maximum wheel load.
Customer must compare
OEM vehicle load rating
to maximum wheel load rating.
Refer to tire manufacturer’s
recommendation for proper
tire pressure. Before mounting
the tire perform a wheel
fitment check to insure proper
clearance from any
obstructions.
NOTICE: When match
mounting tires on Alcoa wheels
locate valve stem adjacent
to low point mark on the tire.
NOTICE: Alcoa aluminum 19.5"
RW and non-symmetrical
wide base wheels require tires
to be mounted and demounted
over the disc side of the
wheel only.
NOTICE: Refer to tire
manufacturer’s
recommendation for proper
tire pressure.
WARNING A pressurized tire/wheel assembly can explode and separate
violently.
This violent separation can cause serious injury or death.
Always contain the tire/wheel assembly in an inflation cage during inflation.

tubeless tires
(continued)
Position wheel on machine. Lubricate wheel
(entire air chamber surface) and tire bead using
approved lubricant. Tire beads should be
mounted over the rim flange closest to the
wheel well. Push bead over flange as far as
possible.
Insert curved end of tool between bead and
wheel flange with tool stop against flange. In
circular motion, use short successive bites to
work the bead over the flange. Push down on
tool as bead is worked over flange.
12
Lubricate the second tire bead. Start second
bead into the well, holding it in position with
the clamp to the rim flange. Lubricate bead
half way around. With curved end of tool
between tire bead and flange, and the stop
towards the wheel, push tool outward to work
tire over flange. Continue to pry bead over
flange using the tool until remaining bead is
over flange. Seat the tire bead using an air ring
or other mechanical bead seating aid.
Place tire/wheel assembly inside safety cage
or other suitable restraint (refer to OSHA rule
1910.177, paragraph b, see Section 7, page 44).
Refer to tire manufacturer’s recommendation
for proper tire pressure. Using a clip-on air
chuck or a self-locking straight chuck with remote
valve and pressure gauge, inflate the tire/wheel
assembly to proper pressure. If air escapes, roll
tire or use bead expander to force tire beads
against rim. Be sure to stay out of the path
of potential exploding parts or air blasts.
