“Tyre Tear Switched fulltime about 6 months ago to these General Grabber AT3 (manufacture 2021) that I had as spares and recently noticed this tear on the surface. Not sure if it's from road debris or a bottle, but wondering what it means for the tyre integrity. Done about 7,000 kms in these”

“General Grabber AT3, Africa and a 2x4 Benz Hi y'all, I'm Norman and together with my girlfriend Mélanie we are close to our dream of riding our 2x4 Mercedes Transporter from 1986 from Switzerland down to South Africa. We'll be taking the west coast road and are overly excited for this two years long trip. We are planning the trip so, that we will be during the dry season in West Africa. Of course the 2x4 is probably not the best choice but should be manageable with a couple aluminum recovery boards, cords, shovel and trucks claws (these traction things to strap around the tire) and last but not least some (5 in total ;) General Grabber AT tires along with a compressor and a puncture fixing set... Puuuh, sounds a lot but is it enough? What are your thoughts?? I mean we'll be doing it ANY WAY. Because a smart man once said "You'd be crazy NOT to go". Just interested if we should consider anything else? Thank you so much for your time 🙂 Mélanie and Norman For everyone who's interested how it will go:”

“How long have I got? Grabber at3s, plenty of tread but I’m seeing some cracks forming. Are these something I need to be concerned about imminently or am I safe to continue driving for a few more months?”

“Another for the AT3 EV. If you search around you can get them cheaper. I got mine for $328/tire out the door, but I had to wait a few days for them to arrive, as there were none of them in my region at the time.”

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.
Community buzz from Reddit and forums is shown for context only — it never changes the score.
