The focus of the P Zero Race is entirely on maximum performance. The tread design is identical to that of the tubeless-ready version of the same name, as is the rubber compound used. The P Zero Race is made from the new SmartEVO compound. With over 110 years of motorsport tradition, Pirelli has developed a blend of three functional polymers with "intelligent" properties that form the foundation of SmartEVO's outstanding performance. Each of the three polymers has specific performance characteristics. In combination, they guarantee the optimal balance of grip and rolling resistance. However, what is completely new in this model is the nylon carcass construction with 120 TPI, designed for use with inner tubes and in compliance with the new standards for 19C rims according to ETRTO. A performance clincher tire that is at home on the road and fits any modern rim. Not tubeless compatible, not hookless compatible.
