I personally think a truck should feel like a truck when i drive it- solid. The stock SR-A's are crap and squish all over the place without loading the bed up sure they are smooth but thats because they are a soft compound, they wear fast and don't do spit for anything rougher than pavement. On top of that I loaded up some laminate flooring the other day and thought for sure I was going to blow an SRA out. I know that stuff is pretty heavy so I calculated it out I had roughly 1400lbs in it, thats a significant weight addition so i noticed the squishy to the max. My next tires will be BFG's and definetely more plys.
