We haven't collected enough community discussion about this tire yet.
General Grabber AT3
Community feedback for the General Grabber AT3 is largely positive, with owners highlighting strong tread longevity, smooth ride comfort, and low road noise. Drivers also appreciate its off-road capability in gravel, mud, and snow, though occasional questions arise regarding sidewall damage, cracking, and tire sizing fitment.
“I feel not many people in this group will like this but I'll post for the hell of it. Some 215/60/17 general grabber at3 I fitted to my A4 to test if it would fit from the standard 225/50/17”
“I have ran the cooper at3 and they are great for a mostly highway tire. I just put the grabber a/tx on but don't have many miles on them yet, went with then because they are more aggressive than the at3 but not as heavy and crazy like my previous st maxx. I have no experience with falken. For what you need it if you're tires the AT3s will be good, they are not loud. My new generals have a bit more noise.”
“Only got 32K on them and installed General Grabber AT3. Took a 2000 mile trip and I think the all terrain tires ride better and look bad ***.”

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.
