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.

Themes extracted from owner reviews found online — not the opinion of TireWheelGuide.
From Reddit, forums and review threads. Not part of our score
Community sentiment toward the General Grabber A/TX is largely positive, with owners frequently praising its winter traction on snow and ice as well as its quiet highway ride. Buyers appreciate its availability in lighter standard load ratings and competitive pricing compared to rivals like the BFG KO2. Minor drawbacks cited include fuel economy loss with heavier LT versions and a tendency for the tread to pick up and fling gravel rocks.
“Thanks Coldcase, you always come through. Im thinking of going for the General Grabber A/Tx, 1 vehicle from the link you posted is using them and even a bigger size at 285 without any issue, difference is they have the altitude package instead of Overland. Do you think ill be fine?”
“Quote: Originally Posted by Teddydogno1 I think I am going to get these for my 2002 SCab FX4. Price and rating both seem very good. How do you like them (those that have them)? Rob I like them a lot. I have about 12000 miles on them. They have a little noise, but not bad if that is a factor for you. I am running them at 38 psi and the ride is a little softer. If I had one complaint, I run a lot of gravel roads and rocks will stick in the tread. When I get up to highway speed the rocks come out and come out hard. I have factory rims so my tires don't stick out beyond the fenders except a tiny bit. I have a couple nice rock chips on the side of my truck from that.”

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.

I was looking for an AT that would be great at hooking up in dry weather but probably not gong to find an AT that is sticky enough. They're brand-new so I'll give an update after a few hundred miles or so (I don't put a lot of miles so it'll take time). Thanks to the Forum for the info! This looks nice!”
“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!”

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.
