Issuing Committee
The responsibility of the Truck and Bus Wheel Committee of the Truck and Bus Brake and Advanced Driver Assistance Systems Steering Committee is to initiate, develop, review and approve the recommended practices, standards, and information reports related to hubs, wheels and the wheel mounting systems of buses, trucks and tractor-trailer combinations intended for highway use. The Wheel Committee is constituted so as to be aware of other SAE wheel activity and to prevent duplication of effort.

listed in the Revision History that contain a radio button. A
redline comparison of the current version against a revision is
accomplished by selecting the radio button next to the standard and
then selecting 'compare'. At this time, Redline versions only exist
for some AMS standards. SAE will continue to add redline versioning
with ongoing updates to SAE MOBILUS.
