What real owners are saying

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

Tire A

Cooper Discoverer S/T Maxx

Positive

The community generally praises the Cooper Discoverer S/T Maxx for its exceptional dual-purpose performance, offering low road noise and strong traction across various off-road conditions like mud, rocks, and sand. Users note good handling while towing heavy loads, though some mention a slight softness or different feel during cornering that does not negatively impact overall safety. While initial purchase costs can be high, overall satisfaction is very high with many loyal repeat customers.

Tire B

General Grabber A/TX

Positive

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?”

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.”

“I've got just over 10,000 miles on my General Grabber A/Tx's and I love them. For the terrain I cover, they are great. If you're looking for a mud tire, these aren't going to clean out very well (probably similar to an average A/T like a BFG KO2). But in the deep snow and ice, they've been great. They are also amazingly quiet on the highway, and on loose dirt/gravel they have done really well. I don't have enough miles to tell you how long they will last, but going off how they are wearing right now, I'm optimistic I can get 40,000 miles out of them (I rotate my tires every 4,000 miles).”

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.
