  • Strong snow and ice performance, including a Colorado snowstorm and multiple Alps trips with up to a foot of snow
  • Comfortable, smooth ride and good handling and braking on the road

Cons

  • Poor wet-weather traction reported by several reviewers, including wheelspin, lack of confidence on wet roads and ABS activation issues
  • Some reviewers found road noise high on paved surfaces, and one called it outrageously noisy, though others found it quiet
  • Wear is faster for some owners, with one set nearing replacement after about 20,000 miles and two years

Tire A

BFGoodrich Trail-Terrain T/A

We haven't collected enough community discussion about this tire yet.

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

“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.”

“Suggestions for replacing AT tires on SUV I have an expedition, and used to need AT tires because of where I used to live and work, but now find I don't need them. I was running some Cooper Discoverer AT3 4S. Absolutely fantastic tires, but now I want to get some all weather since its mostly suburban and highway driving. We get a lot of snow so that's important to me as well. Any suggestions or real world advice? Thanks!”

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.
