aggressive AT tire

Had these Coopers installed this morning. Drove back home on a mix of interstate and Ohio back roads. It snowed last night so some roads were covered with about 1" of snow and others were dry. Tires handled great. Had a tad more road noise than the Mastercrafts they replaced (you can see them in bed in one of the pictures) but I'm not driving a 1 ton diesel because of the smooth quiet ride it has. As soon as I got home I drove around one of my fields and the tires done great. They had 3 other E rated AT's in stock so I was able to directly compare them. These and the Toyo At's were the most aggressive looking tread and looked like both weighted heavily towards off-road ability. The Wildpeak At 4 and Pirelli scorpion AT plus looked less aggressive and more weighted towards on road manners. These Coopers had the most aggressive sidewall biters out of them all and spacing between lugs that was atleast as wide as the Toyos and wider than the other two. These coopers were the least expensive. Cooper and Toyo were the only two Made in USA. They all had the 3peak snow designation. Tread depth looked the same between the Wildpeak, Toyo and Cooper and looked more than the Pirelli. None of these tires are Super Swamper aggressive but they did well in my snowy field and I believe they would do well on the job site or going down an abandoned coal mine road in Southern West Virginia. So if you're looking for a tire with good road characteristics and still pretty aggressive off-road these Coopers are what you're looking for.

Truck tires

The tires are really nice. I got them a day before a big snow storm hit and they handled the roads very well. Much better than the Firestone tires that came with the truck.
