The P ZERO Race TLR RS was developed specifically for racing purposes, making it one of Pirelli’s fastest and most high performing cycling tires to date. Maximizing the balance between speed, handling and grip, the P ZERO Race TLR RS features SpeedCore technology and Pirelli’s SmartEvo compound, along with a newer TLR bead design for even better compatibility and air retention. SmartEvo Compound features a blend of smart polymers inherited from the Motorsport expertise, blending grip and speed, together. SpeedCore brings a thinner rubber layer that allows for better handling, while the aramid fibers dispersed in the blend provide the necessary mechanical strength.
