Default backspacing ?

Hey guys

I have a 1998 formula BMP going to put twosome ccw chrome classics on there. I have a few minor questions what's the biggest size tire on the rear I can use without rolling the fenders or fender rub? I would like to put a 275 on the front with a 315 on the rear. Any help will be great.

Up front with a 17"x 9" a +35 offset up to a +46 offset., or with a 17"x 9.5" a +38 up offset to a +46 offset. Then for the rear a 17" x 10.5" with a +44 offset up to a +50 offset.

You might need a adjustable PHB to center the rear end from side-to-side as with any wide rear wheel/tire set-up, but you shouldn't need to roll the rear fender lips. if your car is lowered or soon to be lowered then I'd get a Adj. PHB and just to be on the safe side verify the rear tire to fender lip clearance.
