The truck's pretty heavy. The extra plies are good even on-road. Ever driven near construction and find a nail or screw in your tread? I've lost a few reduced-ply car tires over the years to this sort of thing. There's a lot of force on those small objects at highway speeds, especially, on a 6000 lb vehicle. Lost one truck tire to a sharp 2" rock chip in Colorado that apparently was flipped up from the side of the road by another vehicle. I lost a car tire to a partial turtle shell in Missouri, ripped a 5" gash in the bottom of the tire. Wife hit a pothole on an entrance ramp in South Carolina that flattened the tire to the rim lips. Bent the lips almost flat and ruined the rim, plus ripped a nice gash completely across the tire. Had a 6" long piece of wood puncture tread on one SUV tire, at an angle that popped it out through the sidewall, too. None of this stuff was even done at excessive speed. Just normal driving.
Personally, I like heavy tires, strong sidewalls, and lotsa plies. I'd even like to add kevlar reinforcement like the tires on the president's limo.
You can run any tire you want as long as it's rated for the load. Ram seems to think we should have a 2900 lb load rating on the tires. Find a tire rated for that, you're good.
Is your ride suffering? Mine already rides much like a car. Hard to remember I'm driving a truck sometimes. Feel more like riding a Buick or Oldsmobile.
