These wheels have less than the 1 3/4 inch center that is standard on aluminum axle hubs. The bolt pattern works with the hubs but the center hole is not 1 3/4'"I n diameter and won't allow the hub to bolt up to the wheel. These wheels will need to be machined to get the clearance needed for the 1 3/4 " bearing hub on a 1 inch axle. Seems like something in this world should be standard. If you don't have access to a lath then you better make sure the wheel has enough clearance to bolt to the hub.
