5.0_REMEMBER R.I.M.
Three Simple Steps To Help Keep Shops Safe
READ INSPECT MOUNT
R.I.M. is a training program developed by HennessyIndustries 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 infl ation.
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 fl y 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.
For more details, contact your Coats distributor or e-mail us.

Page 19
12.0_IDENTIFYING AND CHECKING THE RIM AND TIRE
Before you start to demount the tire, it is of CRUCIAL IMPORTANCE to identify the measurements of the rim and of the
tire. Also make sure neither is damaged.
ATTENTION: These procedures are very important and are to be performed to reduce risks of the tire bursting when
re-mounting the tire on the rim and infl ating it.
All rims bear an indication of their diameter, width, number of humps etc. If we take the picture below as an example,
you can see that:
A= 8 Nominal width of the rim in inches (1 inch =25,4 mm)
B = J Size of the fl ange
C = 15 Nominal diameter of the rim
D = H2 It indicates if there is a double hump (anti bead removing edge)
The tire bears a considerable amount of details, among which are the dimensions, type and maximum speed.
For example: 205/65 R 15 91H TL
A = 205 indicates the width of the tire, in other words the distance between the
sides, expressed in millimetres.
B = 65 is the ratio expressed in percentage between the height of the section
and its width.
C = R Type of tire (R = radial)
A
BC
8Jx15H2
B
A
C
D
E
D
F
G
D = 15 indicates the keying diameter in inches (diameter of wheel), which must
be the same as the rim.
E = 91 is the index of the maximum load born for each wheel.
F = H is the maximum rated speed of the tire. (H= 130,5 Mph -210Km/h)
G = TL means that the tire is Tubeless
WARNING
ATTENTION: It is strictly forbidden to mount tires on rims that have different parameters
(diameter and width). It is also forbidden to mount tires with different dimensions compared
to those stated.
Operation Manual - COATS PRO GUARD PLUS - 19
Page 20
13.0_POSITIONING THE VALVE
Fig. 6 shows a rim in the form of a clock, so that, following the various
processing phases described hereafter, (chapter entitled Mounting and
Demounting), you can position the valve and its sensor correctly so as
not to damage them.
CAUTION
To avoid damaging the valve and the pressure sensor, if
the latter is installed, you must always arrange the valve
in the position indicated, following the instructions when
mounting and demounting the tire. fi g.6
14.0_TIRE CLASSIFICATION
LOW PROFILE tires (UHP) are those in which the height (H) and the width (C) have a ratio lower than 0.5 (i.e. low
profi le series 45 stands for a ratio of H/C = 0.45).
For tires to be considered as LOW PROFILE (UHP), they must also have a maximum speed code of equal to and/or
higher than V.
fi g.6
RUN-FLA T tires are those which, even when they have no internal pressure, allow you to continue to drive the vehicle
for a preset number of miles and at a preset speed. These parameters change from one manufacturer to another.
The market currently offers 2 different types of RUN-FLAT tires:
- Those with REINFORCED SIDE (SELF-SUPPORTING) where, thanks to a different mix and a reinforced structure,
the shoulder of the tire is able to bear the weight of the vehicle even when the pressure in the tire is zero.
- Those with INTERNAL SUPPOR T have a ring inside the rim that bears the side of the tire when there is no pressure
inside it. The internal support may be made of plastic (Pax-System) or of metal (Support-Ring).
The tire changer is able to handle all types of LOW PROFILE (UHP) and all types of RUN-FLAT tires with REINFORCED SIDE; for other types, refer to the specifi c instructions of the dedicated accessories, if available.
The mounting and demounting procedure is the same, be it a RUN-FLAT tire with REINFORCED SIDE (SELF-SUPPORTING) or a LOW PROFILE tire (UHP).
CAUTION
It is of crucial importance to follow the instructions very carefully in order to avoid irreparable
damages to the tire, which could compromise the vehicle’s safety.

15.0_TIRE LIFT
A conventional rim is a wheel of a vehicle with rim made of steel or light aluminium, with a center hole and a drop center
near the edge of the rim.
A reverse mount rim is a wheel of a vehicle with rim made of steel or light aluminium, with a center hole and a drop
center near the bottom patch of the rim.
- Using a special tool, remove any wheel weights on the rim, being particularly careful not to damage the rim.
- Make sure none of the tools are in the work zone of the LIFT so that it is free to position the wheel correctly.
- Position the wheel on the spindle using the LIFT, as follows:
- Move the wheel on the lift platform of the machine, in vertical position with the outside face of the tire facing left.
- Using the lifting pedal, raise the platform and the wheel up to the fl at position and align the center hole of the
wheel with the spindle fl ange.
- Lower the LIFT and center the anti-rotation device.
For wheels bigger than 24-inches or when clamping reverse mount rims wheels, you may need to
widen the plastic rollers of the lift and/or change the angle of the rollers bracket before lifting.

20.0_INFLATION
DANGER
Tires are to be infl ated with utmost caution. Strictly follow the instructions here after as the tire changer
is NOT designed and manufactured to safeguard the user (nor anybody else standing near the machine)
if the tire should accidentally burst.
CAUTION
ATTENTION! If the tire bead fails to fi t in place during infl ation at the maximum pressure of 40 PSI (3.3
bar), you need to repeat the bead loosening and lubricating procedure of the tire itself and then try infl ating again.
DANGER
If the tire should burst or the rim should break under pressure, operators could be seriously injured or even killed.
Make sure the rim and the tire are the same size.
Also check the state of wear of the tire and the rim to make sure there are no defects
before starting to infl ate.
Infl ate the tire with short blasts of air and check the pressure frequently while infl ating.
All our tire changers are automatically limited to an infl ation pressure of 61 PSI (4.2 bar).
NEVER EXCEED THE PRESSURE RECOMMENDED BY THE MANUFACTURER WHATEVER THE CASE.
Keep hands and body as far away as possible from the tire during infl ation.
• Connect the infl ation hose to the valve of the tire.
• Make sure the rim and the tire have the same diameter again.
• Make sure the rim and tire are suffi ciently lubricated; lubricate if necessary.
• Press and release the infl ation pedal continuously, checking the pressure on the gauge frequently until the tire
bead fi ts completely on the rim.
• Continue infl ating to reach the pressure recommended by the manufacturer. Always infl ate in short blasts and
always checking the pressure while doing so.
• Press the defl ation button to defl ate the tire if, during infl ation, the pressure exceeds the value recommended by

ONE WORD FOR SAFETY
R.I.M.
READ INSPECT MOUNT
READ…
Mounting and infl ating 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.
Infl ation 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 fi ngers too
close to infl ating 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 infl ating 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-infl ate the
tire, even if the bead doesn’t seat. Never
infl ate 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
infl ation.)
9. Beads will not
Seat at 40 PSI.
10. Improper
Infl ation.
Remember R.I.M. (Read, Inspect, Mount) for every tire.
