P/N 5900171 — Rev. C — Dec. 2019
Wheel / Tire Mismatches
A Wheel / Tire mismatch is mounting a Tire where 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,
yourself
, 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
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.
• Check for yellow and red dots. If found, line them up with the appropriate locations on the Tire.
• Make sure the Tire is
fully
deflated.
When mounting a Tire, you mount the bottom Bead first (over the top Rim), then the top Bead.
To mount a Tire
:
1. Make sure you are wearing OSHA-approved (publication 3151) Personal Protective Equipment:
leather gloves, steel-toed work boots, back belts, hearing protection, and ANSI-approved eye
protection (safety glasses, face shield, or goggles).
2. If the Wheel is not already secured on the Turntable with the Narrow Side facing up, move the
Wheel onto the Turntable and secure internally or externally.
3. Apply Tire lubricant to the top and bottom Beads and the top Rim.
