Ill be running in hard pack and mud/snow
I would also look at Firestone Destination MT. I was looking at them as well, but didn't want to spend the extra money on them. A guy who works for us on our farm had the Firestones and lives on a gravel road and he doesn't drive slow on them either, they lasted about 3 years before he had to replace them. He abuses tires living on a gravel road, never rotates them. He went with Maxxis Buckshot tires and said they are great tires, the Nankang are very similar and cheaper that's why I went with them. When ever the time comes to replace them I may get the Firestones or what ever else is out at the time that I like.
The Nankangs are amazing on hard pack and the highways, haven't gone down any gravel roads yet, mud I had to learn how the tires gripped as to how to use the throttle, as for snow I can't say right now, maybe this next winter I'll have some feed back. I'm happy with them more every time I ride on them.
