General Grabber AT2 similar tread design as a BFG A/T but at 2/3 the price. Similar performance and road noise. I have had them on my wife's jeep for about 2 years, 25K miles and they are near the half way mark to being wornout. I don't know how well they do in mud but then are great for trail riding and snow.
I've never been skydiving, but I have zoomed-in on Google Earth really fast.
