It's been a while since I have looked at this site, but anyway......I'm running 15x14 wheels with 39.5 Boggers mounted up. I noticed the wide wheels put a lot of strain on the driveline, so I want to go back down to a smaller rim. Plus the tires stick out pretty far on the truck. The question is, 15x10 or 15x12? I was pushing for the 15x10, but maybe the extra 2" the 15x12 gives would help on the wide tire. Any comments or suggestions welcome.
