I see those 20in on front. I have the same dropped spindles and 3 inch coils (5/7 drop) and the tires are not that close to the top of the fender. Of course their 255/60/15 on front. It rides great by the way.
Guess I better stick to 18s when the time comes...
Sorry it won't let me load the pics anymore... says they're now too big (you can look at my previous posts to see my truck)
