2. Proper matching of components before
assembly
17 |
Wheel & Rim Safety Manual
Inspect All Parts for Matching Before Assembly:
Rims and rings must match by size and type. Be sure all
the parts of your assembly are matched correctly. Remember: Just because parts arrive together does not
mean they belong together.
WARNING:
Mismatched tire and rim components may explode and cause serious or
fatal injury.
The size is stamped on every GKN rim base or side/lock ring. The stamping is generally found on the
rim base near the valve slot/valve hole. If you cannot read the stamping on any part, do not use the
part. Such parts should be destroyed and discarded.
Rim components must not be interchanged except as provided for in the OSHA Multi-Piece Rim
Matching Chart. For information on how to get free copies of this chart see
OSHA Standards for
Servicing Multi-Piece
and
Single Piece Rim Wheels, 29 C.F.R. 1910.177, Appendix A.
Be sure your tire size is approved for your rim. Wheels and rims may accommodate tires of varying
widths.
Be sure the diameter shown on the tire exactly matches the diameter stamped on the rim base or
side/lock ring. Do not rely on “eyeball” estimates. Even a small difference could result in an accident.
To aid in identifying matching components, GKN Armstrong Wheels applies a warning decal to the
tire side of the rim near the valve slot/valve hole on the following rim/wheel diameters:
14.5”
16.1”
16.5”
17.5”
19.5”
22.5”
24.5”
