Re: studded snow tires...anyone use them?
Are you actually going to take your motorized bike off road and out into the snow? Having nearly 300 studs will handle black ice better but the gnarly knobs aren't meant for pavement. I think the Nokian Mount & Ground might be a better choice. They will likely squirm less, roll faster, last longer, and wake fewer neighbors.
I log about 30 miles on studded tires every year. Not much really but it's the red air days and the ice heaped up on the shoulders forcing me out into traffic that keeps me off the bike. I have an old set of studded IRC Mud Mads that don't fit either use very well: too narrow for deep snow, too knobby for pavement, and I average two years between true slop rides.
