When I did the diesel swap in the rig in my signature I went from 235-85 16's to 295-70 17's but I also regeared and went from vac boost to hydro boost those changes gave me better braking and handling as well as better mileage at 75mph.......but it was done looking at the big picture and included to get the final drive ratio I wanted.The added weight of the larger tires is not as large a percentage of the equation in my Crewcab with it's curb weight of 8,000# the Cooper ST maxx's are the best tires I had on this truck in the 25 years I've owned it so I can't say hoe well it would behave with smaller ST maxx's unsprung weight is more of a concern in a lighter vehicle than it is in my "tank".
