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.
This is my second time I purchased this tire for my heavily modified pw80, the last one served me grate use for 4 years of abusive all terrain riding. The tread pattern works grate in sand, mud and wears very slow.the side walls are pretty tough and withstand being driven flat multiple times in the event of a popped tube. overall this tire is so grate you will buy a second one.
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.
Recently used tire in trials competition under dry and rocky conditions and was very pleased with traction on loose off chamber turns and dry rocks covered with silty dust ...also the tire seems to be wearing very well. Cannot report on wet conditions as of yet but due to the softness of the tire, I would expect good results as well.
I've had my rear on for 700 miles and it has split vertically between several tread blocks near the mold lines. I'm waiting for a response from the manufacturer to see if there was a and batch or something but I would not buy these tires again.
