Well, I finally got these things out in some mud and trail riding not snow related. I am even more impressed now. There is absolutely no roughness to the tires at all, and the ride has improved so much I can't believe it. Putting radials on your bike is the equivalent of putting $600 shocks on it. I also learned that you have to check your tire pressure carefully, as 1/2psi and 5psi look the same when walking around the machine. (I didn't ride it for a couple of weeks and found a leaky valve stem)
Very good traction, and the 26" size is perfect for this bike. No rubbing and more clearance, with not noticeable power loss till top speed. Even then, it's likely the same, just won't pull the same numbers on the speedo, but likely is doing the same ground speed.
Excellent traction over wet logs, rocks, and uneven/slow going stuff in the woods as well as really good side bite when trail riding. You will never drift these tires though, you will flip the machine first, so keep that in mind. I have found excellent bite in the mud too. Haven't found anything I couldn't get through yet, but haven't buried it in the swamp yet either. Have to go out with the guys so I have someone to winch off of before I try the big holes.
All in all, these have worked out way better than expected. I just wanted more traction for light mud/rocks/woods and figured if I could give up just a little ride/roughness for that I would be happy. I never would have figured on making the machine ride better with the extra traction and clearance, not to mention the looks! I love these tires
