15 vs. 14 inch rims

The small bolt pattern will limit your choices. I had Crager ss 14 X 6 (4" bolt pattern) wheels on my duster, which looked great. I had 60 series bfg radial t/a 225's up front, and 245's in the rear. The 245's ballooned a bit on that 6" rim, so I later switched to 235's all the way around. In the end, it's up to you. I happen to like the dog dish look though as well.
