Initial Impressions
bought brand new for a 2012 nissan titan. Put about 20k on them. Still had 85% tread and good sipping still. I got them on a buddys word that drivers a Ram 1500 as his daily driver. In Minnesota we need decent snow and ice traction more than rain or wet traction. There was a road hum to them but it was not bad at all for a/t tire. Very surprised at the traction on icy roads and lighter snow. It was very good. Even when towing the tire performed well in the ice and snow. Sidewall was a bit soft at time though. It did struggle some in deeper snow above 5 inches or more. Overall a good tire. I would buy it again if they still made them (discontinued). I would give the tire an 8 out of 10. Better for daily drivers in all conditions with lite off road/ towing. I did go thru a few muddy farm fields they were decent not great. Struggled to clean out but i did not get stuck!

Was a better tire than the factory ones, just didn't get the mileage out of them that I was wanting, even though I rotate and balance them every 5K miles

Used these for 55,000 miles on my Ram 2500 truck, mostly highway towing a toy hauler. Road manners were excellent. Wet, dry, snow. All very good. Lasted over 50k which is great. They handled the muddy min maintenance roads I have to deal with ok enough. Able to get back in the trail and rescue broken jeeps a few times. For your average truck that needs 8 hours of highway in between an hour of back woods roads it's a great quiet, and long lasting option.
