Rolling diameter . You want to be within 3-5 % of the factory rolling diameter . If you change the rolling diameter , your speedometer will NOT be accurate . Learn to trust Tire Rack . I have been to their shop in Indiana . They are no joke .

Don't always trust TireRack. If you were to put a 185/60R15 on a 15x7 it will be stretched and look like cartoon balloon tires, I know I did it when I first got my wheels. I rode them like that for 2 weeks before I relized how silly it looked, then I went to my 225/50's
