First time jeep owner. 2010 wrangler sport stock, I'm thinking about buying ION alloy series 174 15x8 rims with 3.5 backspace. I'm also thinking about a lift kit of 1.75" or 2". What size BFG Mud Terrains could I put on without any rubbing, or any other complications on the road or trail. Thanks. I've just been reading so many posts with all kinds of formulas, all kinds of cutting and what not. My head is spinning. Thanks again.
