Just to prove that Fred is correct (which I don't have to do. LOL!) my buddy has a tub'd 1996 Camaro SS. The tires in the rear are, I think 31" tall (or 33"?) and the tires in the front are skinnies which, I think, might be a little less than stock diameter or maybe the same... not exactly sure. Bottom line is that his rear tires have a much larger diameter than his fronts and his ABS works fine with no ABS "error" lights.
