Mine are hub piloted buds. The lug nut is beveled to center the rim. I think that is what you mean. ???
Incorrect.
Hub piloted wheels the hole in the center of the wheel will fit snug on a lip machined on the hub.
Stud piloted wheels the wheels have a large "chamfer" at each lug hole and the lug nuts fit this "chamfer".
to confuse the issue many hub piloted wheels use chamfered lug nuts and a separate clamping plate that has chamfered holes. you can not judge a wheel by it's nuts alone, you must actually look at how it is mounted.
It would be very helpful if you could tell us what the bolt circle diameter is, then we can give you your options on replacement wheels.
