Operator Protective Equipment

Personal protective equipment helps make tire ser­vicing safer. However, equipment does not take the
place of safe operating practices. Always wear durable
work clothing during tire service activity. Loose fitting
clothing should be avoided. Tight fitting leather gloves
are recommended to protect operator’s hands when
handling worn tires and wheels. Sturdy leather work
shoes with steel toes and oil resistant soles should be
used by tire service personnel to help prevent injury
in typical shop activities. Eye protection is essential
during tire service activity. Safety glasses with side
shields, goggles, or face shields are acceptable. Back
belts provide support during lifting activities and are also
helpful in providing operator protection. Consideration
should also be given to the use of hearing protection if
tire service activity is performed in an enclosed area, or
if noise levels are high.

READ INSPECT

R.I.M. is a training program developed by Hennessy
Industries to help keep tire technicians safe. By follow­ing the basic principles of R.I.M., technicians can avoid
situations that can cause catastrophic accidents like tire
explosions.

R.I.M. stands for read, inspect, and mount:

Read the tire size on a new tire before mounting to

make sure it is the proper size for the wheel.

Inspect the wheel for cracks, rust, and or other dam­age that could cause an unsafe situation.

Mount the tire safely, making sure not to put any part
of your body over the tire during inflation.

The most serious of possible accidents is a tire explo­sion. This is often caused by a tire/rim mismatch.

If a tire explodes on a tire changer, pressure causes it
to fly straight up at tremendous speed. If a technician
is standing over the tire, he can be seriously injured or
killed.

Hennessy’s R.I.M. program allows the technician to
avoid situations that can cause tire explosions and other
accidents. The full program, including training videos,
brochures, posters, and other materials, is available
from Coats distributors nationwide.

The unit must be properly operated and properly
maintained to help avoid accidents that could damage
the unit and injure the operator or bystanders. This
section of the Operating Instructions manual review
basic operations and use of controls. These instructions
should be reviewed with all employees before they are
allowed to work with the machine. Keep these instruc­tions near the machine for easy reference.

necessary to reinflate to 5 PSI to loosen the opposite
bead.

NOTE: Always loosen the bead on the narrow side of

the wheel’s drop center first (motorcycle wheels may
not have a narrow or long side, and some ATV wheels
may bolt together). See Figure 4 for more information
on the drop center.

REMEMBER: The clamps on the table top may extend

beyond the table top itself. To avoid damaging the
clamps, move them to their full inward position before
positioning a tire for bead loosening.

CAUTION

This machine may operate differently from
machines you have previously operated.
Practice with a regular steel wheel and tire
combination to familiarize yourself with the
machine’s operation and function.

Remember to remove all weights from both sides
of the wheel. Weights left on back side of wheel may
cause the wheel to be clamped unlevel. This may result
in the combination mount/demount tool contacting the
rim causing scratches. On alloy wheels, always rotate
the wheel one turn after setting the tool to insure proper
wheel chucking.

NOTE: Always review nicks and scratches with own­ers of expensive wheel and tire combinations prior to
servicing.

IMPORTANT: Review the performance wheel section
of this manual prior to servicing performance tire/wheel
combinations.

1. Deflate tire completely by removing the valve core

from the valve stem (Figure 1).

NOTE: Use extra care in positioning the bead loosener

shoe on larger wheels/tires, and on alloy wheels. Make
sure the shoe rests next to but not on the rim, and not
on the tire sidewall.

2. Pull the bead loosener shoe away from the machine

and roll wheel into position. The valve stem should be in
the 3 o’clock position. Position the bead loosener shoe
against the tire next to, but not on, the rim. Depress the
bead loosener foot pedal to actuate the shoe and loosen
the bead. It may be necessary to loosen the bead in
multiple locations around the tire (Figure 2).

Motorcycle

Figure 2 - Position Tire and Bead Loosener Shoe

3. Turn wheel around and repeat loosening procedure

on the other side of the wheel. This should be the long
side of the drop center.

ATV

TIP: It will be easier to clamp the wheel to the table

top if the lower bead is loosened last.

4. Apply tire manufacturer’s approved rubber lubricant

liberally to entire circumference of both tire beads after
loosening.

Figure 1 - Remove Valve Core to Deflate Tire

NOTE: Loosening the beads on a fully inflated tire
is unsafe and causes excess movement and friction
against the bumper pads and excessive wear on pivots.
Deflate the tire completely to prolong the life of your
machine.

ATV NOTE: It may be necessary on ATV wheels to
leave 3-6 PSI in some of these wheels to facilitate bead
loosening. Even after loosening one bead; it may be

clamp, observe the style and strength of the wheel
and adjust the clamp pressure as necessary using the
pressure regulator and gauge. Thin spun aluminum
rims sometimes used on ATV and motorcycle are
sometimes delicate and a reduced air pressure should
be considered verses cast aluminum and steel wheels
that can support more clamping force.

5b. Next, observe the rim size from the tire, i.e. 15,

16, 17, etc. Using the clamp pedal, place the clamp valve
in the JOG IN position for prelocating the clamps to
the rim diameter. Accomplish this by moving the pedal
from the UP position to the 1/2-DOWN location. Then
JOG the pedal DOWN allowing the clamps to move
inward until the pointer on the clamps align with the rim
diameter on the table top decal. It may be necessary to
relocate the clamps on the clamp carriers. Each clamp
should be in the same position before prelocating the
clamps.

5c. Determine the mounting side of the wheel. The

mounting side is the narrow side of the drop center.
(Tire removed in Figure 4 for clarity.)

7. Move the swing arm into position. Pull the lock-

ing handle forward to release the slide. Push down
on the top of the vertical slide to move the demount

tool into contact with the
rim edge. Push the lock­ing handle back to lock the
slide into place. As the
slide is locked, the mount/
demount tool will move
upward approximately 1/8
inch from the rim edge.

Note: On plastic mount/

demount tool, the upward
movement should be lim­ited to 1/16-inch maximum.

Figure 6 - Position Mount/Demount Tool

8. The mount/demount tool roller should be in contact

with the rim edge. Turn the swing arm adjusting knob
to move the tool away from the rim 1/8 to 1/4 inch.
On expensive and polished rims, it is recommended a
plastic bootie (p/n 8183373) be used over the mount/
demount tool roller.

6. Place tire/wheel assembly on table top with

mounting side up (Figure 5). Use the clamp control
pedal to move the clamps inwards (push pedal down)
or outwards (toggle pedal up). Clamp motorcycle and
ATV wheels from the outside (clamps push inwards
against the outside rim edge). Place rim flange into rear
clamp and slowly move the other clamps inward until
they contact the rim. Observe closely to prevent tire/
wheel damage.

Figure 7 - Adjust Swing Arm to Position Tool Roller

9. Check tool positioning. Mount/demount tool should

be positioned with 1/8 to 3/16” clearance between the
top of the rim edge and the bottom of the tool (with
plastic mount/demount tool it is recommended the ver­tical clearance be limited to a maximum of 1/16-inch),
and 1/8 to 1/4 inch clearance between the rim edge and
the tool. This clearance will be maintained as long as the
locking handle and adjustment knob are not changed.
The operator may swing the arm out of the way and
back into place again without needing to reposition the
tool (when changing a set of the same wheels).

tool over the forward end of the demount tool and
below the top bead of the tire. Use your free hand to
press down on the tire opposite the tool to help with
tool insertion (Figure 9).

13. Lift and hold the tire at an angle so that the lower

bead is resting in the drop center directly across from
the demount tool, and is loose below the demount tool
(Figure 11). Insert the smooth curved end of the bead
lifting tool down over the forward end of the mount/
demount tool and below the lower bead. Lift the bead
up and over the knob on the demount tool (Figure 11).

Motorcycle

ATV

Motorcycle

ATV

This information must be read and followed carefully to

prevent accidents and injuries during mounting.

Check tire and wheel carefully before mount­ing. Make sure the tire bead diameter and
wheel diameter match exactly. Consult
the Rubber Manufacturer’s Association
for approved rim widths for tire sizes. Mis­matched tires and wheels explode.

CAUTION

Never Mount a tire and wheel handed to you
by anyone without checking both tire and
wheel for damage and compatibility. Be extra
cautious of persons without knowledge of
tire service. Keep by-standers out of service
area.

Never mount a damaged tire. Never mount a
tire on a rusty or damaged wheel. Damaged
tires and/or wheels may explode.

6. For top bead, rotate the table top until the valve

stem is directly across from the mount tool. Lift the
upper bead up and over the rear of the mount tool. With
your left hand press down on the tire between the mount
tool and the valve stem to hold the tire in the drop center.
Depress the table top pedal and rotate the tire until the
bead is mounted. Continue to press down on the tire
during the remaining mounting process.

Do not force the tire onto the rim. Bead dam­age could result making the tire unsafe and/
or creating the risk of injury.

NOTE: If table top rotation stalls, reverse the table top

momentarily until the tire bead is again loose on the
wheel. Reposition the mount tool, make sure the bead is
correctly positioned in the drop center of the wheel, then
attempt mounting again.

NOTE: For low profile or stiff sidewall tires, it may be

advantageous to use the bead lifting tool to initially hold
the upper bead down in the drop center, or use drop
center tools.

NOTE: For tube type tires, mount the lower bead first,

move swing arm out, install the tube, and then mount
the upper bead.

Important: Always read and follow operating instructions. • 7

The clip-on chuck allows the operator to
keep hands and entire body back from inflat­ing tire. Improper use of the clip-on chuck
could result in personal injury. The chuck
must be an open/freeflow style with all
parts in proper working order.

CAUTION

Check for proper inflation gauge operation.
Accurate pressure readings are important
to safe tire inflation. Refer to the Operat­ing Maintenance section of this manual for
instructions.

The inflation pedal, located at the center of the left
side of the machine, controls the flow of air through the
inflation hose, and has three positions.

Note: The clip-on chuck on the end of the hose should
always be an open/freeflow style with all parts in proper
working order.

Position 1 - Tire Pressure – With the inflation hose
attached to the tire valve and the pedal in this position,
the air gauge will register the air pressure in the tire.
Whenever your foot is removed from the pedal, it will
return to this position.

Position 2 - Tire Inflation – This is the first activated
position. With the inflation hose attached to the tire
valve and the pedal in this position, line pressure is
allowed to flow through the valve system and into the
tire for inflation. Correct tire pressure is not indicated on
the gauge in this position.

Position 3 - Bead Sealing – This is the second and
last activated position. With the inflation hose attached
to the tire valve and the pedal in this position, line pres­sure is allowed to flow through the valve and to the

Inflation Pedal Positions (RC150)

The inflation pedal, located at the center of the left
side of the machine, controls the flow of air through the
inflation hose.

Note the Pedal Positions (See Diagram)

Use of bead sealing jets without a tire in
place can cause dirt and debris to be blown
into the air with enough force to injure
operator and/or bystander. Do not use the
bead sealing control position to inflate a tire.

R. This unit is equipped with a pressure limiter to

assist the operator with proper tire inflation. When the
inflation pedal is held in position 2, the pressure limiter
cycles the machine between position 2 (inflation) and
position 1 (at rest, no airflow to tire). This cycling helps
to prevent over inflation of the tire. Tires can still be
over inflated and explode with the use of this pressure
limiter if all of the instructions in this manual are not
followed completely. The pressure limiter will keep
most car and light truck tires from inflating beyond 60
PSI (smaller tires may reach higher pressures). It is
the operator’s responsibility to follow all instructions
and to control inflation pressure as specified in these
instructions. Check the function of the pressure limiter
regularly and maintain it according to the instructions
provided in this manual for safe and proper operation.
Do not tamper with or attempt to adjust the pressure
limiter. Tires requiring inflation beyond 60 PSI should be
inflated in a safety cage.

Bead Sealing

1. Position valve stem in front of operator and con-

nect the inflation hose with the clip-on chuck. Hold
tire up against upper edge of the wheel. Be sure tire’s
top bead does not cover the bottom of the valve stem
(figure 16).

Bead Seating

NEVER exceed 40 PSI to seat beads while
using this tire changer. If more than 40 PSI
is permitted by tire manufacturer, ALWAYS
use safety cage and clip-on chuck. NEVER
exceed recommended pressure after seating
beads. ALWAYS keep hands and entire body
back from inflating tire.

An exploding tire, wheel, or bead sealing
equipment may propel upward and outward
with sufficient force to cause serious injury
or death to operator or bystander.

Figure 16 - Lift Tire Upwards for Bead Sealing

2. Depress inflation pedal to position 2 and hold about

one second to begin air flow through tire valve, then
depress pedal to position 3 and hold briefly — less than
one full second. The blast of air from the jets will expand
tire and seal the beads.

3. Release the inflation pedal and allow it to return to

position 1. Verify that both beads are completely sealed
to the wheel. Repeat these steps if beads have not
sealed. It may be necessary to wait a few seconds for
the air storage tank pressure to recover before attempt­ing again.

S. If tire and wheel are properly lubricated and operator

cannot achieve bead seal after three or four attempts,
the valve core may be removed from the valve stem to
allow more air flow into the tire to assist with bead seal.
After bead seal is achieved, remove the clip-on chuck
and reinstall the valve core. Reattach the clip-on chuck
after core is installed.

Check tire pressure frequently. If operator is
unable to obtain Bead Seat, something is
wrong. Deflate tire completely, inspect tire
and wheel, correct any problems found, relu­bricate both tire beads, and reattempt Bead
Seal and Seat procedures. Follow all safety
instructions in this manual and on machine.

1. Once tire pressure is indicated on the air gauge

(inflation pedal in position 1; foot removed from pedal),
continue to inject air into the tire (inflation pedal posi­tion 2) in short intervals. Check the pressure frequently.
Stand back during bead seat. Keep hands, arms, and
entire body away from tire during this procedure (figure

17).

Figure 17 - Stand Back during Bead Seat

14 • Important: Always read and follow operating instructions.

Inflation

NEVER exceed tire manufacturer’s recom­mended air pressure. Tires can explode,
especially if inflated beyond these limits.
Use clip-on air chuck, keep hands, arms
and entire body back from inflating tire.
Avoid distraction during inflation. Check
tire pressure frequently to avoid over infla­tion. Excessive pressure can cause tires to
explode, causing serious injury or death to
operator or bystander.

1. Make sure both beads are seated. When both

beads are seated, the tire is ready for inflation.

2. Replace the valve core if it was removed.

3. Depress the inflation pedal to position 2 to inflate

the tire. The pressure limiter will cycle the air flow as
described earlier. On most tires, the pressure limiter
will cease air flow at approximately 60 PSI. On smaller
volume tires the pressure may be higher.

6. ATV Tire Inflation: ATV tire inflation is unique in

that the bead seat pressure allowed is more than the
operating pressure. ALWAYS follow the tire manufac­turer’s information on inflation. This information can be
printed on the sidewall, on the tire sticker, or from the
manufacturer.

4. Release air pressure from tire by pressing the

manual release valve button (inflation hose must be
attached to the valve stem, Figure 18). Never add or
adjust tire pressure using an air hose without a clip-on
air chuck and in-line valve. Do not use a hand-held style
chuck (figure 19).

5. Important: When inflating automotive, light truck,

and motorcycle (ATV see note 6) tires that require more
than 60 PSI, always use a safety cage and air hose with
a clip-on air chuck and in-line valve. The air hose must
have enough length between the chuck and the opera­tion/in-line valve to allow the operator to stand outside
the trajectory.

Explosion Hazard

Never exceed 40 PSI while

seating beads. If you use
more than 40 PSI always

use safety cage.

Remember R.I.M.

Stages of Infl ation on a

Conventional Tire and Rim

Review these descriptions and diagrams carefully. Refer to them as
necessary during bead sealing, bead seating, and inflation to verify that
you are proceeding properly and safely.

Bead Sealing

Bead sealing is the process of capturing air pressure between the
tire and the rim. The tire will usually contain about 1/2 to 2 PSI at initial
bead seal.

Bead Seating

Bead seating usually occurs on the long tapered side of the wheel
first and the shorter side last. Bead seating will usually require at least
7 PSI in the tire. 40 PSI is the maximum safe pressure at this stage
regardless of tire operating pressure. For tires requiring more than 40
PSI to bead seat use safety cage.

Most European import cars and many aftermarket alloy wheels are
very tight and can be difficult to bead seat. Also note that asymmetrical
hump and run-flat tires are extremely difficult to bead seat. Follow tire
manufacturer’s recommended procedure for bead seating.

Inflation

After the beads are seated, the tire is ready to be inflated. Do not
inflate the tire above the manufacturer’s recommended pressure as
stamped on the tire sidewall. The typical inflation pressure for auto­mobile tires is between 24 and 45 PSI. Light truck inflation pressure
typically covers a wider range.

16 • Important: Always read and follow operating instructions.

Mismatched Tires and Wheels

Never mount and inflate mis-matched tires and
wheels.

Mismatched tire and wheel combinations will explode,
if you attempt to force a bead seat, causing personal
injury or death to operator and/or bystanders.

Important: Always read and follow operating instructions. • 17

Performance, Custom, and

Aluminum Automotive & Light

Truck Wheels

To avoid personal injury or finish damage
to components only tire technicians with
experience and training on custom wheels
should attempt to service expensive custom
alloy or aluminum wheels, high-performance
low-profile tires and EMT/run-flat tires.

CAUTION

Many tires/wheels have pressure sensor
devices that are manufactured by different
companies, there are no standards on type
or mounting; therefore, follow the instruc­tions that apply to the sensor being serviced.
For further information on these devices,
contact the individual sensor manufacturer.

Pre-Operation Notes:

• Ensure all weights have been removed.

• Assistance will be required on wide and large
diameter wheels.

• Clamp wheel from the outside.

• Use ample lubricant for mounting and demounting

• Always review wheel nicks and/or scratches with
the owner before servicing.

2. Some wheels have a low-pressure sensor/trans-

mitter strapped to the wheel. This is especially true on
older run-flat tire/wheel systems. To avoid damaging the
sensor, always loosen the top bead with the valve stem
at the 2 o’clock position first, to determine sensor loca­tion. Then loosen the bottom bead and the remaining
circumference of the beads as necessary at a location
that will not damage the sensor. (Figure 21).

Follow these instructions for performance type tires
and wheels, including run-flat tires and their associated
wheels, and asymmetrical hump wheels.

1. Remove the valve core and completely deflate the

tire. On many performance wheels a valve type sensor
may be inside of the rim. These devices are expensive
and should be serviced with care. After deflating the
tire, loosen and remove the retaining nut and then tap
lightly with a hammer to allow the valve sensor to fall
inside the tire before further service work (figure 20).

Figure 27B - Outside Clamped with Tire Removed

Tip: This is usually accomplished by crouching down

in front of the tire changer, holding the wheel with the
right hand, and operating the clamp control pedal with
the left hand. This allows the operator to watch the
clamps as they move inward to ensure proper, clamp­ing.

lifting heavy tire/rim assemblies onto the
tire changer.

Important: Always read and follow operating instructions. • 19

9. Depress the tire sidewall downward with the aid

of the helper foot providing clearance for the mount/
de-mount head to be positioned (Figure 28). Move
swing arm into place. Increase the horizontal distance
between the demount head and the wheel an additional
1/16 to 1/8 inch with the adjustment knob.

12. Place the helper foot opposite the demount

head and push the bead into drop center. Insert bead
lifting tool between knob on demount tool and tire bead
Figure 31). Use roller tool to provide clearance.

10. Lubricate upper bead liberally. Use the bead roller

tool to help push the tire bead down so bead area is
easier to reach for lubrication (Figure 29).

Figure 29 - Lubricate Upper Bead

11. Locate the valve stem just before the demount

head before proceeding (Figure 30).

13. Rotate lifting tool down over wheel to lift bead up

and over the knob and at the same time remove helper
foot (Figure 32).

Performance Tires & Wheels • Mounting

Before beginning any of the mounting activities, review
all of the caution, warning and danger instructions asso­ciated with mounting already listed in the early part of
the manual concerning tire/rim size match, inspect for
damage, etc.

14. Install or review condition of any pressure sensor

devices. This will prevent having to remount the tire
later.

15. Begin the tire mounting process by lubricating

both tire beads and the rim if necessary (figure 33).

18. Position the valve stem 90 degrees clockwise in

front of the mount/demount tool for top bead mount­ing. Lift the bead over the rear of the mounting head.
Use the helper tool to hold the bead in the drop center
(Figure 35). Rotate the wheel in short steps and apply
extra lubricant to mount upper bead.

Figure 35 - Mount Upper Bead, Use Helper

19. On extremely tight tire and wheel combinations,

it may be necessary to use the bottom of the helper
foot to flip the tire bead over the rim flange (Figure 36)

Figure 33 - Lubricate Tire Beads

16. For mounting the lower bead; position the tire at

an angle to the rim and mount (figure 34).

Figure 34 - Mount the Lower Bead

17. Next position the rim for the best mounting

by assuring the valve stem or sensor devices will not
prevent the upper bead from using the wheel’s full drop
center. Typically valves or sensor devices are positioned
at 90 degrees forward of the duckhead.

Custom and Special Wheels

CAUTION

Only tire technicians with experience and
training on custom wheels should attempt
to service expensive custom alloy or alu­minum wheels and high-performance low­profile tires.

Alloy Wheels

Some manufacturers offer wheels with little or no drop

center. These are not DOT approved. The tire or wheel

- or both - can be damaged and the tire could explode
under pressure , resulting in serious injury or death. Do
not mount/demount this type of wheel (figure 37).

Oil Injector Maintenance

The oil injector (on units so equipped) typically require
annual service. The oil level in the oil reservoir tank
should be checked regularly.

Add oil to oil reservoir tank when fluid level is a quarter
full or below. Remove cap from the oil reservoir tank
and add Chevron Regal
oil is an acceptable substitute). Replace cap and clean
up any spilled oil.

Important: An air lock will form if the hose between
the reservoir and injector is ever empty of oil. In this
case, after filling the reservoir tank, the line must be
bled of air at the injector connection as follows:

1. Disconnect all power sources, both air and electric-

ity inputs. Allow any stored air in the reservoir to escape
by depressing the inflate pedal.

2. Remove the side panel and locate the oil injector.

Pressure Limiter Maintenance

Operating a tire changer with a defective,
improperly adjusted, or by-passed pressure
limiter could cause an operator to acciden­tally over pressurize a tire, resulting in a tire
explosion with severe injury or death to the
operator or bystanders.

6. Replace pressure limiter if it fails to cycle properly

during inflation, if it fails to shut air supply off at 60 PSI,
or if it malfunctions in any other way. Do not operate
machine with a faulty pressure limiter.

Watch
Pressure on
Both Gauges

Always be sure that the pressure limiter is
present and is operating properly.

Never inflate tire above manufacturer’s rec­ommended pressure after bead is seated.
Pressure limiter is set at 60 PSI. Any required
inflation above 60 PSI should be performed
in an inflation chamber/safety cage or
securely mounted on the vehicle if an infla­tion chamber is not available. A tire explo­sion may cause personal injury or death to
operator or bystanders.

The pressure limiter helps prevent inflation of standard
size or larger tires or tubes beyond 60 PSI to minimize
risk of explosion. This device is for the safety of the
operator and bystanders. Proper operation of the pres­sure limiter is essential to safe operation of the machine.

Check operation of the pressure limiter as shown and
described below at least monthly:

1. Remove tires and/or wheels from the machine.

2. Connect the inflation hose to an empty service

tank with a pressure gauge (gauge should read 0). Use
a certified tank with at least 200 PSI pressure rating.

3. Depress inflation pedal to position 1 to start airflow

through the hose and into the tank. Maintain a steady
pressure for constant flow.

4. Watch the rising pressure on the tank gauge and

the gauge on the machine. Machine gauge should
cycle between check and inflation pressures while tank
gauge climbs steadily. As tank pressure reaches 60 PSI,
the pressure limiter should stop the airflow automati­cally. Both gauges should read 60 PSI ± 5 PSI.

5. Release inflation pedal. Check manual release

valve function by pressing the button and releasing
pressure from the tank until it reaches 50 PSI. Discon­nect inflation hose, and release air inside tank.

ONE WORD FOR SAFETY

R.I.M.

READ INSPECT MOUNT

READ…
Mounting and inflating the
wrong size tire can get
you hurt. Read the size on
the tire and make sure it
matches the rim. Be espe­cially careful about putting
a smaller tire on a larger
rim, such as a 16-inch tire
on a 16.5-inch rim.

Inflation of a mismatched
tire and rim can cause an
explosion.

BE CAREFUL OF THESE SITUATIONS:

1. Damaged Bead or
Beads.

2. Rusty Wheels.

(particularly in the
bead seat area)

3. Bent or Cracked
Wheels.

4 A. Mismatched.

(A mis-match of a
16-inch tire to a 16.5­inch rim causing an
explosion)

4 B. Mismatched.

(16.5-inch tire on a
16-inch rim)

INSPECT…

Before you put any tire
on a rim, inspect the rim
for rust, tough spots, bent
edges, or cracks that could
prevent the tire from seat­ing right. If you spot any
of these problems, don’t
mount the tire until the rim
has been checked by your
shop foreman.

Inspect the tire for bead
damage.

5. Walk-In Tire and
Rim.

6. Back Injuries.

7. Hand or Finger
Injuries.

(Hands or fingers too
close to inflating tire
or bead seats which
may cause injury.)

MOUNT…

Once you’ve made sure the tire is OK
and the right size and the rim is OK,
mount the tire safely. NEVER, ever lean
over the tire when you’re inflating it. If
a tire does explode, it will go straight
up. You don’t want to be over the tire
if that happens. Also, never over-inflate
the tire, even if the bead doesn’t seat.
Never inflate over 40 PSI. If the tire
hasn’t seated, something is wrong.
Deflate the tire and check it and the
rim again. If it doesn’t work the second
time, try another tire.

8. Standing Clear.

(Never put any part
of your body over the
tire changer during
inflation.)

9. Beads will not
Seat at 40 PSI.

10. Improper

Inflation.

Remember R.I.M. (Read, Inspect, Mount) for every tire.
