I have 245/60/15 BFG's on 15x7 4.25 custom SBP rallyes on my small bolt pattern 68 Dart. It it real real close inside and out. One side closer than the other. When you switch to new large flange large bolt pattern axles the flanges themselves are thicker than the SBP and everything moves outward a little. Pictures of my Dart are on my FABO picture page.
