Tire B

Cooper Discoverer AT3 4S

Positive

Community sentiment for the Cooper Discoverer AT3 4S is predominantly positive, with drivers praising its quiet highway ride, strong traction across snow, rain, and dry pavement, and appealing appearance. Several owners note that while it handles light off-road duties and daily driving well, tread life occasionally falls short of mileage expectations.

“Cooper Discoverer AT3 4S discontinued, good alternative? I was hoping to replace my stock tires with the Discoverer AT3 tires since I hear really good things about them and they are a bit more aggressive. Seems like they are discontinued at all the normal tire shops online. So what are my alternatives for an AT style tire? Looking for 235/60R17 to put on Drag DR-31 rims. I live in CO so snow and some light off roading are things to consider. Read more”

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.
