Well I mounted up a 369X with a pieced together moose and went and rode 45 miles of super rocky King of the moto stuff and it worked very well. After 45 miles it still looked great, it is a non directional tire. So looks like about 150 plus miles one way and then turn it around and get another 100 miles. Don't let the look of the tire bother you, as it looks like a dual sport tire. But it is worth trying
I now have over 100 miles of extream endure type riding on the tire and it still is holding up well. Most in rocky stuff, but I did do some sand dunes and it also worked there. I plan to race Rd 1 of the Nationals with a 369x. Yes it is over kill but I will not have to wait in line at the hills as with this tire I can climb around anything
