“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.”

Tire A

Goodyear Wrangler MT/R with Kevlar

We haven't collected enough community discussion about this tire yet.

Tire B

Cooper Discoverer AT3 XLT

Positive

Community opinion of the Cooper Discoverer AT3 XLT is overwhelmingly positive, with users frequently praising its smooth ride quality, exceptional quietness on the highway, and long-term durability compared to competitors like BFG KO2 and Toyo Open Country. Drivers also appreciate its solid value and performance when towing. A few users occasionally confuse the M+S marking with the Three-Peak Mountain Snowflake rating for severe winter conditions.

“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.”

How do we compare tires?

Every category score blends two independent signals. 60% comes from professional tire tests (braking distances, lap times, noise measurements), each result compared with every other tire in the same test and newer tests counting more. 40% comes from owner reviews found online, adjusted for how generously each site rates. Both use one scale: the average tested tire gets 70, the best 100. When a tire has only one of the two, the missing half is estimated from the other and the score stays closer to average; with no road test and fewer than five owner reviews it gets no score yet.

Community buzz from Reddit and forums is shown for context only — it never changes the score.
