I have a set of 265 50 15's on the rear and 225 50 15's on the front of my ride, all mounted on Americans, simulated bead-lock. No problem here with clearance and no mods...
Here's some data on the wheels and tires if ti will help:
Wheels/Tires from Pep Boys
- Rear wheels; 15x10 AR 73, stock #735165 ... Front 15x7 AR 73, stock #735765
- Tires; Rear = Futura GLS P265/50R15 ... Front = Futura GLS P225/50R15
When these were bought and installed ( May of 99), wheels went for $63 rear and 46 front {each} , tires $57 each... not a bad investment for a good looking set of wheels and tires...
