Ok rims are warped on my burb. Tire store did what they could but it rides like hell. Said that brake heat can cause this on steel rims when towing heavy weights. PO towed a 31ft 7k camper with this truck. Infact probably more then 50k of the 74k on the turck was with this camper behind it. Anyway I found a set of take offs from a 2003 3/4 ton truck with 5k on them. These are the current Mags on the 3/4 Silverado trucks. Does anybody know what the back space would be on these? My worry is it will be to deep. I need around 4 inches of back space.
