ok on the 6th i will be purchasing a rock krawler 3.5 lift and spidertrax 1.75" spacers. and i want to know if 245/70/17 will fit? i keep thinking in my mind that they will but just want to make sure. oh and the type of tire im getting is a BFG M/T KM2
That tire will fit easily. In fact it's going to look small IMO. Even though the RK lift isn't going to net you 3.5 inches of lift. It is going to get you around 2. You would be better suites to get some 265/70/17's.
