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.

Operating Instructions
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.
Bead Loosening and Demounting
NOTE: Always loosen the bead on the narrow side
of the wheel’s drop center first. 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.
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.
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).
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).
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 (see Figure 4).
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.
Figure 3 - Apply Rubber Lubricant to Tire Beads
Important: Always read and follow operating instructions. • 3

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.
6. Place tire/wheel assembly on table top with mount-
ing side up (Figure 5). Use the clamp control pedal to
move the clamps inwards (push pedal down) or outward
(toggle pedal up). Clamp steel wheels from the inside
(clamps push outward against wheel). Clamp mag and
custom wheels from the outside (clamps push inward
against the outside rim edge). Refer to the Performance
Tires and Wheels section.
Figure 5 - Place Tire/Wheel Assembly on Table Top
7. Move the swing arm into position. Pull the locking
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.
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, and 1/8
to 1/4 inch clearance between the rim edge and the tool
roller. 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).

10. Insert the smooth curved end of the bead lifting
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).
Figure 9 - Insert Bead Lifting Tool
11. Push the bead lifting tool down towards the
wheel to lift the tire bead up and over the knob portion
of the demount tool. Hold the tool and bead in this
position (Figure 10).
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).
Figure 11 - Demounting Lower Bead
14. Depress the table top pedal to rotate the wheel.
The demount tool will guide the bead up and over the
edge of the wheel. Continue rotation until lower bead
is demounted.
Figure 10 - Lift Bead Over Demount Tool
12. Depress the table top pedal to rotate the wheel
clockwise. The demount tool will guide the upper bead
up and over the edge of the wheel.
NOTE: Push down on the tire across from the demount
tool during table top rotation to utilize the drop center
area of the wheel. This reduces the tensional force on
the bead during demount.
NOTE: With tube-type tires, demount the upper bead
and remove the tube before demounting the lower
bead.
NOTE: Table top rotation can be stopped at any time
by removing your foot from the pedal.
NOTE: Normal table top rotation for demounting is
clockwise. Depress the table top pedal to rotate this
direction. To rotate the table top counterclockwise, lift
the pedal up with your toe.
CAUTION
At times during the mounting and demounting procedure, the bead lifting tool may
encounter resistance or come under load.
Keep one hand firmly on the tool to avoid
possible tool disconnect. Use the reversing
feature to back out or jam ups.
Important: Always read and follow operating instructions. • 5
Page 10
Mounting
This information must be read and followed carefully
to prevent accidents and injuries during mounting.
WARNING
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.
3. Lubricate tire beads liberally with tire manufacturer
approved lubricant (Figure 13).
Figure 13 - Lubricate Beads
4. Place tire over wheel and move swing arm into
position. Position the tire so that the lower bead is
above the rear extension of the mount/demount tool
and below the front knob (Figure 14).
WARNING
Never mount a damaged tire. Never mount a
tire on a rusty or damaged wheel. Damaged
tires and/or wheels may explode.
CAUTION
If you damage the tire bead during mounting, STOP!, remove the tire and mark it as
damaged. Do not mount a damaged tire.
1. Inspect the wheel closely for damage. Clean the
wheel and remove any light corrosion or rubber residue
(Figure 12). Do not attempt to service heavily corroded
wheels.
Figure 14 - Position Tire Against Mount/Demount Tool
5. Depress table top pedal and rotate the wheel to
mount the lower bead. Use the drop center of the wheel
to reduce the tensional force on the bead by pressing
down on the tire directly across from the mount tool.
Rotate table top until lower bead is fully mounted.
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.
Figure 12 - Inspect and Clean the Wheel
2. Inspect tire for damage, paying close attention to
the beads. Verify size match between tire and wheel
(Figure 12).
6 • Important: Always read and follow operating instructions.
Page 11
WARNING
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 as shown in Figure 30.
NOTE: For tube type tires, mount the lower bead first,
move swing arm out, install the tube, and then mount
the upper bead.
Inflation
Tire inflation is performed in three steps: Bead Seal,
Bead Seat and Inflation. These steps are explained in
detail on page 10-11. Read the explanation of each step
and understand them thoroughly before proceeding.
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.
CAUTION
If the rim has been clamped from the outside
for tire mounting, release the clamps, lift the
tire, and move the clamps to the center of
the table top.
DANGER
Tire failure under pressure is hazardous. This
tire changer is not intended to be a safety
device to contain exploding tires, tubes,
wheels, or bead sealing equipment. Inspect
tire and wheel carefully for match, wear,
or defects before mounting. Always use
approved tire bead lubricant during mounting and inflation.
The inflation pedal, located at the rear of the left side
of the machine, controls the flow of air through the
inflation hose.
NOTE: The clip-on chuck on the end of the hose
should always be an open style with all parts in
proper working order.
Tire Pressure Tire Inflation Tire Inflation
Position 1 - At Rest – 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 and into the tire for
inflation. 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
air-flate bead seal jets on the table top for bead sealing.
CAUTION
Use Position 3 for bead sealing only. Do not
use this position without a tire and wheel
positioned on the table top. Dirt and debris
could be blown into the air with enough
force to injure the operator or bystanders.
Do not use the position to inflate a tire.
Important: The 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 air flow 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 (small 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.
Tires that require inflation beyond 60 PSI should be
inflated in a safety cage.
Important: Always read and follow operating instructions. • 7
Page 12
Bead Sealing
1. Connect the inflation hose to the tire valve stem.
Hold the tire up against the upper edge of the wheel.
Be sure the top bead of the tire is over the bottom of
the valve stem (Figure 15).
Figure 15 - Lift Tire Upwards for Bead Sealing
2. Depress the inflation pedal to position 2 and hold
about 1 second to begin air flow, then depress pedal to
position 3 and hold very briefly - less than 1 full second.
The blast of air from the jets will expand the tire and
seal the beads.
3. Remove your foot from 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.
Note: If tire and wheel are properly lubricated and the
operator cannot achieve bead seal after 3 or 4 attempts,
the valve core may be removed from the valve stem
to allow more air into the tire to assist with bead seal.
After bead seal is achieved, remove the chuck and
reinstall the valve core.
Bead Seating
WARNING
Operator should keep hands, arms, and
entire body away from the tire during the
remaining bead seat and inflation procedures. Do not stand over tire, as personal
injury could result.
WARNING
NEVER increase air pressure to exceed 40
PSI when attempting Bead Seat. If operator
is unable to obtain Bead Seat, something is
wrong. Deflate tire completely, inspect both
the tire and wheel, correct any problems
found, relubricate both tire beads, and reattempt Bead Seal and Bead 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 in short intervals.
Check the pressure frequently.
Stand back during bead seat. Keep hands, arms, and
entire body away from tire during this procedure.
Tire beads should move outward and “pop” into their
bead seat position as pressure inside the tire increases.
If this does not happen, a problem exists. Investigate
carefully.
WARNING
Check tire pressure frequently. Never exceed
40 PSI while seating beads. Once seated,
never exceed tire manufacturer’s recommended air pressure. Tires can explode,
especially if they are inflated beyond their
limits. At all pressure levels when inflating
through the valve stem, keep hands, arms,
and entire body away 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.
8 • Important: Always read and follow operating instructions.
Page 13
Inflation
DANGER
NEVER exceed tire manufacturer’s recommended air pressure. Tires can explode,
especially if inflated beyond these limits.
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. Check tire pressure frequently by removing foot
from pedal and checking the gauge on the tower. Avoid
overinflation.
NOTE: Release air pressure from the tire by pressing
the manual release valve button (inflation hose must be
attached to the valve stem).

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.
10 • Important: Always read and follow operating instructions.
Page 15
Mismatched Tires and Wheels
Never mount and inflate mis-matched tires and
wheels.
DANGER
Mismatched tire and wheel combinations will explode,
if you attempt to force a bead seat, causing personal

Performance Tires and Wheels • Demounting
Follow these instructions for performance type tires
and wheels, including run-flat tires and their associated
wheels, and asymmetrical hump 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.
Pre-Operation Notes:
• Ensure all weights have been removed.
• Assistance will be required on wide wheels.
• Clamp wheel from the outside.
• Use ample lubricant for mount and demounting
• Always review wheel nicks and/or scratches
with the owner before servicing.
Aluminum and Custom Wheels
Follow instructions provided for standard steel wheels,
except:
A. After loosening and lubricating both beads, rotate
the table top until the clamps are in the 12, 3, 6, and
9 o’clock positions.
1. Remove the valve core and completely deflate the
tire.
2. Pull the bead loosener shoe away from the machine
and roll the tire into position against the bumper pad.
Position the tire with the valve stem in the 3 o’clock
position (in direct line with the bead loosener shoe).
Always loosen the bead on the narrow/mounting side
of the wheel first (Figures 4 and 18).
Figure 18 - Position Tire for Bead Loosening
NOTE: Wheels with an asymmetrical hump have a
larger “ledge” type hump around the wheel except at
the valve hole making them more difficult to mount and
demount (Figure 19).
Figure 17 - Rotate Table Top to 12 O’clock
B. Clamp wheel from the outside. Position rim edge
into clamp at 12 o’clock position. Lower the wheel
and depress the clamp control pedal. Slowly move
the clamps inward until they securely contact the
outside edge of the rim.
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 to ensure proper, damage-free
clamping.

NOTE: Some wheels have a low pressure sensor/
transmitter strapped to the wheel. This is especially
true on run-flat tire/wheel systems. The sensor is positioned directly opposite from the valve stem. To avoid
damaging the sensor, always loosen the top bead at
the valve stem first, then loosen the bottom bead at the
valve stem, and then continue to loosen the remaining
circumference of the beads as necessary (Figure 20).

3. Loosen bottom bead, starting with valve stem posi-
tioned directly next to the loosener shoe (Figure 21).
6. Lubricate upper bead liberally. Use the bead lifting
tool to help push the tire bead down so the bead area
is easier to reach.
Figure 23 - Lubricate Upper Bead
7. Move swing arm into place and adjust as described
on page 4, steps 7, 8, and 9. Increase the distance
between the demount tool and the wheel an additional
1/16 to 1/8 inch with the adjustment knob. Locate the
valve stem directly under the demount tool before
proceeding.
Figure 21 - Loosen Bottom Bead
4. Liberally lubricate the bottom bead of the tire
(Figure 22).
Figure 22 - Lubricate Bottom Bead
5. Clamp the wheel to the table top as described in
item B, page 12. Always clamp custom wheels from
the outside.
Figure 24 - Position Valve Stem Under Demount Tool
8. Insert bead lifting tool between knob on demount
tool and tire bead. Pull lifting tool down over wheel to
lift bead up and over the knob.
NOTE: On asymmetrical hump wheels and stiff side-
wall performance tires, it may be necessary to use 2
optional drop center tools (part #8435685) to hold tire in
the drop center so that the bead can be lifted over the
demount tool.
Figure 25 - Insert Bead Lifting Tool (Optional Drop Center Tools
Shown)
Important: Always read and follow operating instructions. • 13
Page 18
9. Hold lifting tool in place and depress the table
top control pedal momentarily to jog the wheel a short
distance.
Figure 26 - Pull Lifting Tool Down and Rotate Wheel
10. The lifting tool can usually be removed after
jogging the wheel a short distance. Continue to jog
the wheel to allow tire to flex where it crosses the
rim edge. Continue short rotations until top bead is
completely demounted.
Performance Tires and Wheels - Mounting
1. Lubricate both tire beads liberally. Performance
tires will require more lubrication than standard passenger car tires.
2. Mount the lower bead. In most cases, the lower
bead will mount easily.
Figure 29 - Mount Lower Bead, Use Lifting Tool
3. Position the valve stem directly across from the
mount/demount tool for top bead mounting. Lift the top
bead over the rear of the mount tool. Use the lifting tool
to help push and keep the top bead in the drop center
during mounting, or use an optional drop center tool to
help hold the bead in the drop center (Figure 29 & 30).
Rotate the wheel in short steps to mount lower bead.
Figure 27 - Remove Drop Center Tools
11. Demount lower bead. In most cases when
demounting performance tires, the lower bead will be
less difficult. Use help to lift, position, and hold tire. Pay
close attention to sensor/transmitter location, and position it directly below the demount tool when starting
the lower bead demount procedure.
NOTE: Mounting the top bead can be very difficult
when mounting new tires on many performance and
custom wheels.
Figure 30 - Mount Top Bead
Figure 28 - Use Help on Lower Bead, Watch Sensor
14 • Important: Always read and follow operating instructions.
Page 19
4. Mount the top bead using short rotations of the
wheel. As the wheel progresses, a second drop center
tool should be added to keep the bead in the drop
center.
Figure 31 - Add Second Drop Center Tool
5. On extremely tight tire and wheel combinations, it
may be necessary to use the hooked end of the bead
lifting tool to flip the tire over the rim flange (Figure 32).
Figure 32 - Use Hooked End of Bead Lifting Tool
6. After beads are mounted, unclamp wheel, lift it
slightly, and move the clamps to the center of the table
top. With the tire/wheel loose on the table top, follow
the detailed instructions provided in the Inflation section of this manual for bead sealing, bead seating, and
inflation.
Important: Always read and follow operating instructions. • 15

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 33).

European Performance Wheels
(Asymmetrical Hump)
Some European wheels have very large humps except
near the valve hole. On these wheels, the beads should
be loosened at the valve hole on both the upper and
lower sides first (figure 34).
Tube Type Tires
Mounting
1. Avoid pinching or forcing the tube.
2. Apply rubber lubricant to the beads of the tire.
3. Mount the bottom bead.
4. Round out the tube with a small amount of air.
5. Apply rubber lubricant to the tube.
6. Insert the tube into the tire.
7. Mount the top bead.
Demounting
1. After tire beads are loosened, lubricate the beads
and rim liberally.
2. Position demount tool and bead lifting tool as
described in steps 8 through 12 on pages 4 and 5.
Depress table top pedal and rotate only a short distance
at a time. This allows you to stop the process should the
tube get pinched.
3. After upper bead is demounted, remove tube and
demount lower bead.

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.

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.
