I have heard that these wheels will not work with 5/8 studs. The people I heard it from had no evidence to support their claims. I would be using gm bolt pattern 4 3/4" with 5/8 studs. Has anyone or does anyone run these wheels with 5/8 studs? If so, what modifications (if any) did you have to do? If you know why they won't work can you please explain why? Summit has this 15x10 rim for $114. They are suppose to be lighter than prostars, 14.5lbs. I guess they went under? Thanks guys.
