I was looking at M&H Racemaster DR's. They make a P325/45-17 that is supose to be mounted on a 10" rim. The measurments (according to the catolog) is 28"H x 12.1"W (sec.). Tread width is 10.3". Ive seen other people run 315's (12.4"W), but that was a 26" tire. Has anyone run these tires on a 70-72 Chevelle? My car will be lowered and I need all the rubber I can fit in the rear.

Thanks - Ron

Since we know a 17x11 wheel w/6.25" backspace will fit a 68-72,a 17x10 wheel with 6" backspace might work with that size tire. A 325/45/17 will have shorter,stiffer sidewalls than a 325/50/15 and we know how snug the latter tires can be to fit. My guess is the 17" tire will be an easier fit.

Do you happen to know if it is possible to fit a 12" wide wheel in a '69? If I'm going to pay extra to get my 18's stretched to 11 I might as well go all the way to 12" if it will fit.

You might be able to make it fit but the tire size is what will kill you, you might not be able to take full advantage of the 12" wheel without minitubing. Anyways you can fit some seriously wide meats on an 11" anyways.

Good point...I just hate paying $400 extra per wheel to only widen 1" inch. Problem is 10" wide really limits to size.

Anyone have pics and specs. on a 325/50-15? What was needed to fit those size tires? I will be running 17's because of the 4 wheel disk brakes, but I figure if people can fit the 15's, than I shouild have no problem fitting the 17's. Running the larger rim means I can set the tire (off set) in closer to the frame (clears the shock better)
