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.

What drivers say about their 275/65 R20 tyres
The most recent owner reviews fitted in this size, in their own words.
I replace my Firestone Destination XT’s that I loved. After all the reviews I figure these would be even better. Unfortunately, they are not even in the same ballpark. The tires break contact when starting from a stop on wet roads and in the mud the cake up with mud and provide no traction. Very disappointing and can wait to get my mileage out of them and get them replaced.
Very quiet, almost as quiet as the Bridgestones and not intrusive at all in cabin.
The ride is amazing and better than the Bridgestones. Only one area of my daily 100 mile round trip commute is worse than ride comfort wise than the Bridgestones but it’s a totally shyt section of road in New Orleans area. I drive the causeway (23.8 miles bridge) and the ride is better on the KO3s.
I was debating between KO3s and XTM ATs after watching the review on this site. Well, there is a reason Jonathan says the KO3 is the standard.
I’ll post again as they wear.
