I started around 52psi on these, and they really felt squirrely compared to the Pirelli Scorpion All Terrain Plus tires that were OEM. They were the first LT tires for this truck other than my winter set, and I was surprised at how much this bothered me. At some advice from others, I bumped it to 60 psi, and they feel WAY more planted. Dry traction has been great, and they're really capable off-road. We're going into the wet season here and I'm a little concerned about the wet traction. I've done no real testing, but they seem to slip on very heavy acceleration from a stop (R1T quad, so good power) and once or twice on heavy braking in the rain. I haven't felt any lateral slide on turns or anything, so that's a good feeling.
Noise is tough to compare; the OEM Pirellis were known to get VERY loud at the end of their life so these feel quieter than that, but they're still LT tires with a fairly aggressive tread pattern, so they're not going to be silent.
With only 3k miles on them, I'm not seeing any wear, I expect they'll last decently well, or at least have started out strong.
