I had a set of 8's got to say, hated them. Ran them early this year with different trail conditions and different psi. I am here to tell you I will never run them again. They pushed through the turns when the trails were dry and when the trails were tacky they slide skis. Slick Rock Moad is the best place for the tires. I tried a few different tire combos this past year and always went back to something with knobs. My Serac IRC always seemed to work 90% of the time.
