Proper Fastener for X One® Steel
Stud Piloted Wheels
It is important that the proper fasteners be used when mounting the X One® tire stud piloted wheels.
If a fastener specified for the stud piloted aluminum wheel is used on a steel wheel, it will bottom out
on the brake drum and the proper clamping force necessary to help ensure that the torque on the
wheel remains constant will not be achieved, possibly resulting in a “wheel off” situation.
