“They Discontinued My Tire! I've been using Cooper Discoverer AT3 4s forever. For some reason Cooper, in it's infinite wisdom, has discontinued the 265 75r 16 size so I need a replacment. I'm in Southern California and do quite a bit of wildlife habitat restoration work in dry desert conditions. This involves lots and lots of highway miles as well as dirt roads from good to, on what planet is this a road. Occasionally we are even driving up dry washes, trying to avoid all the nasty sidewall eating rocks and spiny bushes. The tread on the discoverer is pretty modest and quite on the highway but when aired downed, runs well in sandy conditions. They even work pretty well in rocky conditions. The other thing is they wear really well. Ive got 60k+ miles on my current set and can squeeze another 10k out of them if I have to. So to the point, Im looking for suggestions for a replacment. Any help would be greatly appreciated.”

“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”

“New tire advice from people who know about cooper Ive had these discoverer at3 4s since 2022. I need to replace them and ive heard they stopped making them. Before this it had discoverer RTX and discoverer LSX tires. The ones people are saying kinda took over are the road and trail AT but they look way more offroad styled then the at3s did. I dont drive offroad but i dont want strictly highway tires. I do drive on the highway though and haul a bit does cooper have anything else or is the road and trail AT a good replacement? 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.
