Well, I ran them thru some really nasty stuff yesterday and they did GREAT. Even got through some stuff in 2WD that I would normally need 4WD. And they ride good on the hard stuff too! And, yes, they are 26" the fronts are 9.5" and the backs are 13"...they are so wide, but I have some offset rims so they don't stick out on the sides too much. I have a 2" lift on the bike and could have gotten a taller tire, but didn't want to lose too much power. Anyway, so far so good!!!!
