What are you running for wheels?

Im looking for the widest rear tires I can get without tubbing the read end or cutting anything. If that limits me to 8" wide in the back and 6.5 in the front then Im perfectly happy with that.

That's almost my exact combo

15x8" (4.5 back spacing) 275/70/15 M&H Racemasters
15x6" 215/70/15 BFG Radial T/As

Be advise if your going Rallye wheels , their are not easy or cheap easy trim ring options.
