I don't know how many tire shops you have in your area but in SE Michigan Detroit sub. there are a ton. The best thing to do is go visit a few tire shops in your area. They should be able to tell you what will fit and what won't. No cost out of your pocket if they mount a tire and it rubs. But don't take one shops word for it becuase they always push inventory and or high dollar items, so shop around.

I don't think 15" will fit on a F-250 powerstoke becuase of the brake disc and caliper size. <img src="/forums/images/graemlins/frown.gif" alt="" /> <img src="/forums/images/graemlins/patriot.gif" alt="" />
