Vittoria's Zaffiro Pro boasts a tough, folding 60-thread-per-inch nylon casing and Vittoria's Twin Tread technology for excellent cornering and rolling resistance. Its high-mileage rubber compound, combined with Vittoria's Puncture Resistant Belting gives you a durable, long-lasting tire with excellent flat protection.
I bought one of these to carry as a spare in my backpack on 100+ mile rides in case one of my mounted tires fails, and I have used it as spare from time to time. In sum I've put about 300 miles on it and find it smooth, with good traction, and I've never had a flat with it. It is a bit heavy so not for racing, but very good as a back up in my view.
Bottom LineYes, I would recommend this to a friend
