Tire A
Pirelli Scorpion All Terrain Plus
We haven't collected enough community discussion about this tire yet.
Tire B
Positive
Cooper Discoverer A/T3
Community sentiment for the Cooper Discoverer A/T3 is overwhelmingly positive, with users frequently praising its low road noise, smooth ride, and strong snow and wet traction. Owners appreciate its long tread life, solid towing capability, and reasonable value, though some note it packs up quickly in thick mud and can become slightly louder as it wears.

“Put a set on a day after I purchased my truck. Have about 8500 miles on them and no complaints whatsoever. Been on a 3000 trip with them not towing and a 2400 mile trip towing a 8K travel trailer. No problems on either trip. I'll get another set when these wear out, hopefully many miles down the road. No sign of wear yet!”

“I have put 18k miles on the discoverer AT/3's on my F150 since last November and have been impressed with them so far. The tread seems to be wearing well, and I haven't noticed any more road noise than the BF Goodrich rugged trail T/As that I had on it before, and the ride quality has also been good compared to other tires. I haven't used them off road much but they did well in snow last winter, and have got good traction on wet pavement. Overall, I'd definitely say their good tires for the money, with their performance and the fact that they come with a 55,000 mile warranty.”

“Just a minor point... The tire in the picture is actually the Cooper Discoverer AT3 LT, not a Discoverer A/T3. They're different models, and Cooper does a really poor job IMO differentiating between them. I had Cooper Discoverer A/T3's E range on my 2nd Gen Tundra and LOVED them. That truck is gone, and now my Taco has Disco A/T3's and I'm finding them every bit as transformative.”

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.
