^^^ Yeah, those X-Ones are not gonna like pavement. You could wear the center knobs off in a week. I did one mostly-pavement 40-miler on Ritchey Shields, and aside from feeling like I was dragging a car tire behind me with a rope, there was visible wear on the knobs after that first ride. Further, CX tires tend to have absolutely no flat protection of any kind, so riding them on the street is likely going to start producing flats sooner than later-- note: this is operating under the assumption that the bike didn't come with the tubeless version.
