i have 15's with 4.25 bs. 10 minutes per side on the 14ff to clear the calipers, As far as drums, they fit right on no problem. If I were to do it again, id get 17's, the only problem is that in 2002 when i did my rim purchasing, 17 were new and expensive, 16.5's just suck for airing down with no beadlocks, and 16's were very limited and the ones you could get were load range d or e. Plus i like the balloon of the tire with a 15 inch rims when aired down to 9 or so psi, they have a huge contact patch for traction.
