I know y'all have probably hit on this a ton. But I'm a brand new jeeper and trying to figure out a wheel and tire combo. I'm pretty set on the BFG KM2's. My jeep is a daily but I still want it to look good and be able to play on the weekends. I guess wheel size is my question, 4 wheel parts is trying to talk me into a bigger wheel? Rather than the run 33x12.5r15, they say I should opt for a 16 or 17? Why?
