I'm coming up on the end of my second year running these tires (25x8-12 Front & 25x10-12 Rear) on a 2010 RZR 800 and have been very pleased. I'll start with my complaints, which are minor. First, the tires run smaller than most heigth wize, and my skinny little machine needs all the height it can get. The other complaint is they don't hold traction as well sideways as other tires I've had on the machine.
So far I have about 750 miles on the tires, varied terrain such as 300 or so miles on trails in the moab utah area with most being difficult trails. Traction was great, ability to ride cracks on just the sidewalls was good, handled both sand and slickrock well. 200-300 miles in the mountains on the Arapeen and Paiute n trails in Utah with lots of jagged rocks. Again, traction was good, and the tires handled the sidewall scrapes without any cuts.
Fore and aft traction are good in mud, but not so great side to side. Only a few miles in deep snow, but they seemed as good as any traction wise there. On the pavement, they're somewhat noisy, and the tread gives you a bit of a vibration. I run my tire pressure between 5 and 6psi most of the time, with most of the places I ride keeping me in 4low, at sub 15mph speeds with much less use at 45 mph or so on dirt or paved roads
