P/N 5900260 — Rev. A1 — Dec. 2020
Push the Bead Lifting Tool towards the other side of the Wheel in an arc, pulling the bottom Bead
over the Demount Lip of the Mount/Demount Head.
While continuing to hold the Bead Lifting Tool, press down on the Turntable Foot Pedal to move
the Turntable clockwise.
Watch the bottom Bead to make sure it is being pushed over the top of the Rim as the Turntable
moves.
Keep turning the Turntable until the entire bottom Bead pops over the top Rim.
The Tire is now dismounted and can be removed.
Wheel / Tire Mismatches
A Wheel / Tire mismatch is mounting a Tire when the Tire’s Bead diameter does not exactly match the
Diameter of the Wheel/Rim.
⚠
DANGER
A Wheel / Tire mismatch is extremely dangerous
. A mismatched Tire and
Wheel may separate or explode, resulting in injury or death.
The differences can be subtle, so you must take care to get an
exact match
.
For example, a 16 inch Tire goes on a 16 inch Wheel, not a 15.5 or a 16.5 inch Wheel. It may be
possible to slide the 16 inch Tire over the Rim Lip of a 16.5 inch Wheel, but during inflation it will
not
seat properly.
⚠
WARNING Do not mount a Tire on a Wheel until
you
, have positively identified and correctly
matched the Tire and Rim diameters. If you try to seat a Tire Bead on a
mismatched Wheel and Tire by inflating it, the Tire Bead may break with explosive
force, which could result in serious injury or death.
More information is available in OSHA standard 29 CFR 1910.177 (Servicing Multi-Piece and Single
Piece Rim Wheels). All Operators should study this document prior to servicing any Tires.
Mount a Tire
Mounting a Tire is the process of putting a Tire onto a Wheel.
⚠
WARNING Mounting a new Tire can be hazardous if not done correctly. Do not change a Tire
unless you have been trained to do so. Failure to understand and follow proper
procedures can result in injury or death.
During mounting, the Tire Bead goes over the Mount Lip of the Mount/Demount Head, but stays under
the Demount Lip. See
Mount/Demount Head
for additional information.
Review the following points before mounting a Tire:
•
Check the Tire and Wheel to make sure they are an
exact
match.
• If desired, replace the Wheel’s Valve Stem before mounting the Tire.
• Make sure the Wheel is both clean and free of balancing weights. Remove any weights and any
corrosion you find on the Wheel;
do not service heavily corroded Wheels.
• Check the Tire for damage;
do not mount a damaged Tire
.
• Check the location of the TPMS and adjust the Tire if necessary. Do not damage the sensor.
