The 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 SpeedCore 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 SmartEVO technology, commonly found in other high-performance tires throughout the P Zero range. - SmartEVO compound uses a blend of polymers to provide maximum grip with a low rolling resistance, allowing for maximum speed and control - Nero HighContrast sidewall delivers a minimalistic yet bold design, enhancing the finishing visual appeal with precise, high definition detailing - 700 x 28 and larger sizes are compatible with hookless rims - Hookless rims subject to ETRTO 5bar/73psi max pressure limitation
