Based on What I've read there are Two tires in the 255/55R18 that are candidates in the 18R bracket for us to chose from.
General Tire Grabber AT2 Tire 255/55R18
BFG KO2 A/T 255/55/18
I found a great writeup disputing the AT2 v/s the BFG KO2; Im considering the AT2's and hoping they will fit with the spacer mod.
Why can't you off road with spacers?
I'm wanting to get these exact rims / tires. couple questions... did you order and install new tire pressure sensors? are the rims you have 35 mm offset? any rubbing? did you have to get spacers and if so, what size did you get?
