Higher is better. The Relative Score follows your weights below; category scores do not change.
Wet grip starts at “Important”. Treadwear starts at “Neutral” here: road tests measured it for at most one of the two tires, so it rests on owner reviews. Move the sliders and the scores update instantly.
Only one of the two tires has a score here, so this weight changes nothing in the head-to-head.

From Reddit, forums and review threads. Not part of our score
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!”

“Been running them on the wifes truck for 3 or 4 years now. They are a good tire, very little noise on pavement, does fine on snow. Cooper Discoverer A/T3 Review”

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.
