I've been very pleased with these tires both on and off road. Road manners are superb, no head shake even at low pressure. I'm now on my third and don't even look at other tires now. Usually get 4500-5000 miles out of one and only change because they do cup a little, but have noticed no ill effects from it. Honestly I could probably get over 6000, but with such a reasonable price why chance it.
I bought this tire along with the V-35 and studded them both. I have one 3 hr ride on them and the traction is amazing. I rode on some snow, ice and firm mud (or soft clay soil). I could feel the tire grabbing in the dirt and I purposefully lugged it up some steep trails just to see how it would hook up. I'm very happy so far, the lugs are deep and spaced far enough apart so it doesn't hold the mud. This tire is super easy to install studs into as well because of the little pocket in the middle of the lugs.
I really like these tires on all of my dual sport bikes. They work well on a wide variety of terrain and also are very smooth and quiet on pavement. Tread life may not be as long as some other brands, but the broad performance spectrum is worth it to have to switch out a little sooner. I can get probably 1500-2000 miles out of a rear tire and double from a front. I would not recommend them for larger adventure style bikes, but anything up to 450-500cc would be fine.
Used the tire in a trials competition where the conditions were dry and rocky. Excellent traction and seems to wear very well. Very pleased with results although have not ridden in wet conditions to be able to rate tire in these conditions.
