Close, 305/75R16 Duratracs. I might go with the 285's now though.
The Pro Comp Wheels are 16X8 steel, im a little worried about the added weight because I have no engine mods yet. Im pretty sure I wont need to mess with the breaks with that set-up though. Backspace is 4.5, ideal. I just want to make sure there is no rubbing and no fender problems that will go with this set-up when on rough terrian (CA and AZ rock climbing and desert runs).
Big concern too is low pressure desert dune 4 wheeling. With 8" wheels I feel like the tire felx at low pressure will be a problem, I might be wrong...
Either way, thanks for the help! Im really excited to put the first mods on my X and put some pressure on the Jeep.
