I was looking for an AT that would be great at hooking up in dry weather but probably not gong to find an AT that is sticky enough. They're brand-new so I'll give an update after a few hundred miles or so (I don't put a lot of miles so it'll take time). Thanks to the Forum for the info! This looks nice!”

Tire A

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. In addition, multiple posts highlight frustration and concern regarding availability and recent discontinuation across various sizes.

“Cooper Discoverer AT3 4s I am struggling to find Cooper Discoverer AT3 4s tyres with size 265/70/17. There seemed to be an acute shortage in the market. I am not keen on BF Goodrich due to the weight and price. I shall appreciate it if anyone with reliable leads for Cooper tyres. What else do you recommend if Cooper is just not realistically available? I can wait till March before I need to get my car tested for renewal of registration. TIA.”

“New tires: Cooper Discoverer AT3 4S Needed a 3PMSF tire and these Coopers edged out the Wildpeak AT3Ws based on wear rating and highway performance. Also, Cooper has a promo right now for a $70 mail in rebate. MPG has been about the same, maybe slightly better. Visually, I like them, more rugged than the stock Falkens. Highway and forest road driving has been solid. Stock size, 215/65R17, on a 2020 TH: 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.
