P/N 5900087 — Rev. B — Jan. 2020
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.
⚠
DANGER
A Wheel / Tire mismatch is extremely dangerous
. A mismatched Tire and
Wheel may separate or explode, resulting in injury or even 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
.
Note
:
If you look for additional information about Tire mismatches, you will notice that some
resources use the phrase “tire mismatch” to mean Tires on a single vehicle with different
tread patterns or from different manufacturers. This is a very different type of mismatch, a
much less dangerous one, and is
not
what we are talking about here.
