I'm running 15 X 8 Weld Draglites w/4.5" BS and 275/50 T/A's on the rear and 15 X 7 Weld Draglites w/ 4.5" BS on front with 225/60 T/A's. Got wheels from Summit. The rear are tight to frame about 3/8" clearance. I've had 4 grown men in car and have never rubbed the tires, even with Hotchkiss 1" lowering springs all corners.
