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 members widely praise the Cooper Discoverer STT PRO for its exceptional off-road traction, towing capability, and dependable handling in mud, rain, and snow. While users note it balances well and rides comfortably for a mud-terrain tire, the most common criticisms involve pavement road noise that increases with wear and concerns regarding tread life on heavy trucks.
“I ran them on my Cherokee for a year. Awesome tire aside from icy roads. I loved the tires off road, They just didnt have enough siping to contend with slippery pavement. Went back to the STT MAXX and had no issues.”
“My new tires. Cooper Discoverer STT PRO”
“I thought I'd throw my two cents in! I put 5 Cooper Discoverer STT Pro tires on my 2015 Nissan Xterra Pro-4 X in 2021. It cannot be overstated - I LOVE these tires! They're great in dry conditions, they're great in the rain, they're great in the snow, they're great on ice - they even drove over a frozen iceberg in my driveway during a winter emergency as though it wasn't even there. There's a little bit of road noise, but nothing terrible. You can definitely "feel" them when you're driving - but I kind of like that. My truck sits outside during all kinds of Ohio weather, and they don't appear to be cracking/dry rotting quite yet. It will technically be "due" for me to get a new set of tires next year. Without a doubt, I'm getting another set of these!! Happy trails, all!”

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.
“Tire recommendations! Current 215/75R-15 GENERAL GRABBER A/TX SL I am going to need new tires and I am wondering if I should buy a different tire than what I currently have. Overall these tires have been great and drive pretty well in the snow in VT and NY. Drive NJ roads year round aswell. Any recommendations?! Much appreciate any advice!! Read more”
“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.”

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.
