“I’ve run Hankook dynapro’s, BFG ko2, Nokian outpost nat, and fallen wild peaks. Currently running Cooper discoverer AT3 XLT - they are definitely the quietest all terrains I’ve had. I would recommend them if they are available in your size - many places like simpletire or priority tire carry them.”

Tire B
Positive
General Grabber A/TX
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.

“Thoughts on the “General Grabber A/TX” Tire? I’m thinking about getting it in a 33” SL rated 275/70r18. This tire comes in at 46Lbs which is super light. $915ish for 4! It’s the only 33”, snow rated, All Terrain, C/SL load range I could find. All the other 33”s are E rated coming in around 60lbs.”

“We finally go out first snow storm of winter. We have 8” of fresh snow on the ground, and below that a half an inch of ice (it rained first then snowed). Initial impressions of the General Grabber A/Tx is good. Way quieter than stock tires on the highway, and good traction on snow and ice.”

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.
