Installation Tips

For off-road use only. The following must be considered when using Speedway circle track wheels for on-highway/street use when the wheel/tire assembly is being balanced. Speedway circle track wheels are lug-centric, which means they are built off of, and must be balanced using, the bolt circle and NOT the wheel center hole. Improper use of a tire balancer that centers the wheel on the hub bore, not the bolt circle, will result in an incorrect reading for rim runout as the center hole is not in the perfect center of the bolt pattern. The only machine capable of performing a lug-centric balance is the Hunter GSP 9700 with the flange plate bolt circle adapter and no centering cone.
