TIRE FAILURE UNDER PRESSURE IS HAZ-
ARDOUS! This tire changer Will Not Restrain
Exploding Tires, rims or other related equipment.

TIRES CAN EXPLODE, ESPECIALLY IF INFLATED
BEYOND SPECIFIED LIMITS. DO NOT EXCEED
TIRE MANUFACTURERS RECOMMENDED AIR
PRESSURE.

AN EXPLODING TIRE, RIM, OR BEAD SEATING
EQUIPMENT MAY PROPEL UPWARD AND OUT-
WARD WITH SUFFICIENT ENERGY TO CAUSE
SERIOUS INJURY OR DEATH TO OPERATOR
AND/OR BYSTANDERS.

DANGER

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 espe-
cially 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.

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.

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, some-
thing is wrong. Deflate the tire and
check it and the rim again. If it doesn’t
work the second time, try another tire.

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 16.5-
inch rim causing an
explosion)

4 B. Mismatched.

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

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.)

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.
