“275/60r20 General Grabber A/Tx Just thought I'd share what my truck looks like with a slightly larger tire size in case anyone wondered. No level, just stock. Good looking tires in my opinion.”

Pros, cons & observations
Themes extracted from owner reviews found online — not the opinion of TireWheelGuide.
Tire A Discoverer A/TR
Pros
- Remarkably low road noise for an all-terrain tire with a deep, chunky tread.
- Excellent wet weather performance and resistance to aquaplaning.
- Long-lasting tread life with high mileage capabilities (some users exceeding 50,000 to 80,000+ kms).
Cons
- Some instances of severe edge chipping and cuts to the steel when used on rough outback gravel roads.
- Tramlining effects in the steering as the tires wear down.
- Off-road capability diminishes noticeably as the tread wears past a certain point.
Tire B Grabber A/TX
Pros
- Exceptional winter and snow traction (3-peak mountain snowflake rated)
- Impressively low road noise and high ride comfort for an aggressive all-terrain tire
- Strong wet and dry road grip with confident handling
Cons
- Noticeable decrease in fuel economy (MPG drop)
- Tread tends to pick up and throw small stones and pebbles
- Mixed reviews on long-term treadwear and longevity

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.”

“Not sure where those ratings are from but all the ratings I have seen on the tire have been on par with other at tires. all 4 cost me 765 installed. My traction in NEPA has been excellent in the snow and wet.”

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.
