I've got a bunch of Ford ton trucks with the 235/85/16's and one '97 four door single wheel F350 with 285/75/16's. The 285's ride a tad better but I think that's because I only run about 50-60 lbs of air in them, the others have 80 lbs or so. The 235's do better in snow and ice, and it's a wash in the mud. The only reason I keep the 285's on the one truck is the extra ground clearance and I have a full set of chains for that truck when it heads out to your neck of the woods. They also help offset the 4.10 gears, as that truck spends a fair amount of time on the highway.
