Pirelli P Zero Race TLR Tire Fast and Efficient Tires can make or break your ride quality. If you want a good race tire, you'll want something that is lightweight, durable, and efficient. The Pirelli P Zero Race TLR is the most performing tire in Pirelli's portfolio, as well as being the first tire with a tubeless technology entirely made in Italy. The design features Speed Core technology in a 120tpi casing, utilizing a layer of compound mixed with aramid that covers the inner layer of the tire, improving the smoothness and the resistance of the rubber. The result is a less stiff, but faster tire. The compound, on the other hand, maintains the same advanced Smart EVO technology, commonly found in other high-performance tires throughout the P Zero range. Features Smart EVO compound uses a blend of polymers to provide maximum grip with a low rolling resistance, allowing for maximum speed and control Speed Core allows for better mechanical resistance, improved air retention, and overall greater flexibility700x28 and larger sizes are compatible with hookless rims SPECIFICATIONSSize700c Conditions Pavement Bead Folding TPI120Compound Smart EVOProtection Speed Core Type Clincher Tubeless Compatible Yes Intended Use Road Race Approximate Weight335g (32mm) | Pirelli | P Zero Race Tlr Tire | Black | 700 X 40 | Rubber
