Don't guess, measure from the base of your wheel studs to your springs to see what spacing you have. Yours is probably different from mine, they can vary a lot. Tire retailers like Tire Rack give you the exact width at the widest part of the tire. Your b/s and offset have to be just right to leave you a 1/2" off your springs. I'll look through my papers to see if I still have that info and get you some pics.
