Get those late-model wheels off of there! They are NOT 4-1/2" bolt pattern, but ever so slightly larger, and WILL snap the studs right off at speed because the wheel nuts are making contact with the wheel only at the outer part of the cone. Very dangerous.

Had to share, Just got back from Hoover Alabama. I went down and traded my truck today for a car off the TRADER PAGE.....
Gonna miss my truck, I'd had it about 14 years!
I believe I'll have some fun with one as well
