Yeah Rimrock will suck now. I can't believe how wide mine is now with the 42's on 15x12 (because of weld on beadlocks) with 2.5 b/s on. I just bolted on my buddy's 42's since mine are out on loan and I was like crap I'm nearly 18" wider than tall. It'd be insanely wide.
Not the best picture but you get the idea. Only an 1" is covered by the fender.
