Anybody running 19.5" tires SRW on a 4x4 4500 crew cab, flatbed? I am wondering how rough the ride is when empty, compared to load range E tires. I am sure the ride is rougher, but how much? Nearly intolerable? I have been convinced that I don't really need 19.5's for what I am doing, but the overkill in me thinks I maybe should run them for the extra margin of safety. I know they are very expensive and overkill. Thanks to those running them. john
