“New Cooper Discoverer AT3 XLT 275/75R20 these ride way better than my old Open Country A/T II”
r/Trucks ·3 upvotes ·2021-03-26

“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.”

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.

Handling is the exception: road tests measure it inside the dry and wet scores, so its own row comes from owner ratings only and starts as less important.
