Disc Wheel Radial Runout Low Point Marking
This SAE Recommended Practice provides for standardized steel disc wheel radial runout low point marking. This
marking is used for match-mounting tires on wheels to minimize assembly radial force variation. It applies to tubeless
15 degree drop center disc wheels for use on class 5, 6, 7, and 8 commercial vehicles.
Rationale: The current SAE Recommended Practice includes both steel and aluminum wheel profiles. None of the major US wheel manufacturers low point any aluminum wheels for use on class 5, 6, 7 and 8 vehicles.
The proposed revision is to add the word “steel” in the scope and to remove the aluminum wheel profiles from the
document to align with industry practice.
