So if you want to use 5/8" drive studs, the holes in the wheels need to be 11/16" diameter. If the wheel is made for use with conical lug nuts it may not work with the 5/8" studs unless it's drilled out and has enough material left to bear on the stud without deforming under hard acceleration.

That is why I am going to go with 1/2" studs, don't want to drill the wheels. Thanks Jack
