So far I've been extremely pleased with mine, and I'm at about 4500miles on them. 3000 of them we're from New Mexico along Route 66 up to SoCal, and up the CA coast to Oregon. I've driven them in the desert, silt and sand, lots of highway, and snow and rain. I went through a monsoon in the Mojave desert going from Las Vegas to Los Angeles.
So far what I've noticed is the rubber compound is softer, so the truck (due to tread pattern and material science) is much quieter on road. The Trail Grapplers were extremely quite relative to their tread pattern. Meaning that as M/Ts they were quieter than Toyos, but that didn't mean they were silent. When I'd get calls in the truck I'd typically have to yell or pull off to the side of the road. With the Ridge Grapplers I can take a call and I don't have to raise my voice. They're about as quiet as all weathers. Simply put the truck itself makes more noise than the tires.
In the rain they also didn't get squirrely, which I've found the mud terrains can become. These stay nice and planted.
In the snow? So far amazing. The Trail Grapplers are exceptional off road and in the mud, but the channels were so deep that they'd pack up with snow and turn in to racing slicks when you hit deep snow. I was up to about 22" of snow yesterday and on moderate hills the truck still kept chugging along.
My rims are 52lbs a piece, being beadlocks, but each wheel is about 114 lbs combined, which is pretty impressive since they're 35/12.50R17s.
I'm really impressed, to me these are the tires to beat.
