I hate to bring up another thread, but I've already ordered the tires and have spent about 20 hours in the last few days researching. I'm going with 285/75R17 tires (33.9x11.2). I'm going with 17x8.5 wheels and a 2" AS level.

What is the lowest offset I can run without risking rubbing on the crash bars? It's a 2016 SCREW. I'm thinking +18, but they are hard to find in a 8.5 width. The ones I really want are +12, or should I go +25 to be safe? Anyone running 34's post your wheel specs and if you rub...I don't want to remove or modify the crash bars...

 

I have a RCSB, with 34s & +18 no Rubby Dubby.

LONEGUN has 0 Offset on his and he reported no Rubby Dubby as well.

These are 34's "295/60" but on a 20" rim. Wheels are +1 offset. I have a RC leveling kit, and the tires did rub slightly on the front crash bar. I ended spreading the bars a bit, and that fixed the problem.
