Installation Tips

For off road use only. The following must be considered when using Aero wheels for on highway/street use when the wheel/tire assembly is being balanced. Aero 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.

Should I be concerned about the lack of safety bead humps for my asphalt race car? Have always run Bassett wheels with the safety bead humps but am interested in these wheels. Just concerned about lack of safety bead humps as I do not fully understand there purpose and advantages if any.
