I've had T7 and T9 Butcher 229 x 2.3 tires - one on a new SJ Evo and another on a new SJ. I love the bikes, but not so much the tires. Specifically, I am trying to love the T7 Butcher 2Bliss Grid tire up front. Things started well. The tire is handsome and looks great. Production quality seems very good - maybe better than a competitive Maxxis tire. The Butcher T7 mounted up tunelessly by hand with no tire tools and inflated perfectly with a regular floor pump. As a bonus it even held pressure overnight with no sealant. So far, the tire is off to a good start. Took it out for a first long ride today and it looks substantial and with impressive knobs. The look of this tire inspires confidence, but that's about it. On the ride, the tire consistently washed out up front in typical dry and loose over hardpack conditions. No tire is ideal in this condition, but my 3C DHF and Assegai are both much grippier and instill more confidence. I started at 26psi, dropped to 22pai and later to 19psi as the tire seems sufficiently large volume that I was confident trying 19psi. Traction improved at 19psi and the performance was almost as good as a DHF at 23psi, but the tire felt squirmy and lacked sufficient support at 19psi. I will try the Butcher T7 a few more times at 21psi to 23psi and see if things improve. I'm reasonably happy with the Purgatory T7 in back and like to have matched brand tires so I want it to work. If the tires continue to let go so early, I'll consider switching to another brand. Kudos Specialized on making the effort to step it up on rubber. These tires are well made, priced reasonably, look great and setup flawlessly. It's great to see so much good engineering and rapid evolution on Specialized mountain bikes , tires and wheels. You are winning me over from the boutique brands!
