“Cooper Discoverer AT3 XLT Picked up a set of Discoverer AT3 XLT from simple tire. With the 4th of July discounts all 4 were under 1k before taxes. I had the AT3 4S on a previous ram and they held up so I’m expecting good things here.”

“Are my Discoverer AT3 XLT snow rated? Going snowboarding and roads require snow tires or chains /cables. I was looking at the sidewall of my Cooper Discoverer XLT and saw there is a small M+S next to the tire size. Is it stupid to assume these are snow rated? I'm not trying to get a ticket for not having chains if I need them, which most places seem to be sold out locally.”

“I’ve run Hankook dynapro’s, BFG ko2, Nokian outpost nat, and fallen wild peaks. Currently running Cooper discoverer AT3 XLT - they are definitely the quietest all terrains I’ve had. I would recommend them if they are available in your size - many places like simpletire or priority tire carry them.”
