I have both new tires and rims, Liberator A/T's, and ProComp Rockcrawlers. The tires were bought quick to pass inspection, and then because they were new, I bought 15x7 rims, shouldve gotten 15x8's. Anyways, I am going to do a simple "2" lift soon, and am going to need bigger tires, so what are my options for the 15x7's? I am not looking for real big, or too tall, will a '31 fit? Thx.
