WHEELS & TIRES – What is the difference between “hub” and “stud” piloted wheels?
Hub-piloted wheels have a center hole machined to a close tolerance and are intended to mate with a hub having a properly sized pilot diameter. The bolt holes will be bored or stamped straight through the center disc which is designed to be fastened with either flanged nuts or a clamp ring using cone nuts. Stud-piloted wheels have a center hole which provides clearance to the hub nose. The bolt holes feature a tapered seat designed for clamping with properly matched cone nuts. The cone angle of the nut must match the cone angle around the bolt hole of the center disc. Failure to properly match these components will result in catastrophic wheel loss.
