Best test result: #5 of 18 in 2022 Consumer Reports All Terrain Truck Tires (tested tread life (miles))

“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”

Tire A

Cooper Discoverer AT3 4S

Positive

The Cooper Discoverer AT3 4S is widely praised by the community for its quiet and comfortable highway ride, excellent wet and snow traction, and solid fuel efficiency. Drivers appreciate its balance of rugged aesthetics and daily drivability, though recent discussions highlight growing concerns over reported product discontinuations and sizing shortages.

“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.”

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.
