I’ve run a few sets of Cooper STT MAXX and I’m on my 2nd set of STT Pros. All of the tires have been on Ram 3500 with a Cummins. Aired up to 75-80 pounds they’ve been okay till it starts getting nasty. Air them down to 25 pounds and my truck moves around like it supposed to. Both of them have a little him on the road compared to the highway’ish tires that come on the trucks.

Whoever said tires were a compromise was spot on. My trucks are used to pull trailers and move around hunting units so I air on the side of more aggressive tires. I get about 50k per set but the last 10k they’re pretty slim on solid traction but still better than the highway tires the trucks come with.
