hey guys i'm lowering my truck down soon and trying to get everything figured out and picked out so when im ready i can order everything and get it done quick. i plan on putting stock springs on truck but i have 2" front spring hangers and a 5" traction bar/block in the rear. i plan on getting a gooseneck in the range of 30-35' and probably a varying loads of 10-15k. what size wheel and tire package is gonna fit the best with little to no rubbing. what kind of weight rating for the wheel and tires should i keep in mind as a min. i would really like to run the nitto terra grappler and probably atleast a 18" wheel.
