...some of the Jag hub assemblies impede fitting anything with a rim-width wider than 10.5" (if that). That's the reason I'm eventually going to an Accurate Machine Products (George Petrus) modified Jag. rear---you can fit 15" as wide as you want over that assembly. I've got as Butler, and one guy says you can put 14" rim-widths under there--one guy had 19" inch wide tiresd under there!
Just suggesting you check, that's all.
