I guess I’m the odd man here. I had a set of 255/85/16 M55s on one of my old 3/4 tons. They were outstanding on everything but ice I thought. Plus they lasted forever and I never had a flat with them.
I looked for them last month when my new 3/4 ton needed skins but they aren’t available in the size I was looking for. I ended up with a set of Toyo Open Country CTs, similar tread pattern to the M55 but larger blocks and more siping. They took about 500 miles to settle down and quit squirming but I’m starting to like them I think. Off-road traction seems pretty good so far, mud and gravel, and they are pretty quiet for a fairly aggressive tire. Time will tell I suppose, I had a set of Toyo MTs on my last truck and they were terrible, noisy, poor traction off-road and worn out in about 20k.
