I just put on a set of 33" BFG KO's. I also have a set of Ranch 9000 xl's set on the softest setting. My truck still rides like a 3/4 ton. Here is the really weird part some times the truck will ride better than other times. I can't figure out if it has to do with outside temperature, colder=rougher ride due to the rubber on the tires being firmer. Or is an issue with my Rancho's. Any ideas?
