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.
Since this is a little different profile than the 90/90-21 spec'd for my KTM 990 Adventure, on a 2.15" wide rim, I was a little apprehensive but for the price, decided to try it. If it didn't work out, I could put it on my EXC 450. First pleasant surprise was the balance. Only needed 1 oz across from the valve stem! I then put 500 miles on with about 100 miles of forest roads and was extremely pleased with the smooth ride on the highways (up to 86mph) and the good bite on the gravely, sandy turns on the forest roads. MUCH better than the previous Heidenau K60 and Shinko 804 or the original Pirelli Scorpion MT90's. I listed my ratings compared to other tires I mentioned. Although I'm very pleased with the handling in the dirt, I would choose something else for aggressive riding in the twisties.
