What is the deal on balancing Styled Steel wheels by the lug holes? I have a set of 15x7's that I am going to put on my 66 with 205/60/15's. Why do they have to be balanced by the lug holes and not the center hole like a normal rim? I remember this came up a while back, but I can't find it on a search.
What harm is caused by balancing by the center hole?
Any thoughts are appreciated.

This was covered in MI / MM / or M&F over the last few months. They determined that mustang SSWs are to be lug-balanced, as opposed to hub balanced. I don't recall why, but was thinking of starting to make some calls to see what local shops had the correct equipment to do so. Dickson

I have about five years in the tire business....
The reason why is because the center hole is not perfectly round on the raised center steel wheels, like Crager SS wheels. Think about it...the center is not bolted to your car the lugs are, therefor you get a much better balance from the lug holes This is the perfered way of balancing.

The lug locations are not machined in reference to the center hub. The lugs are located in reference to the outer rim. Therefore the center hub is not necessarily in the center of the lugs. I just bought a set and had them balanced on the car.
They balanced the tires on the rims first to get the best balance. They actually rotated one of the tires on the rim to improve the balance. They mounted the two best tires on the front and spun balanced all 4 on the car. I was amazed. It's the smoothest ride I've ever had. At 90 still smooth as glass.
