Pirelli has unveiled the P Zero Race TLR SL-R, a cutting-edge road racing tire that integrates the innovative Pirelli Advanced Aerodynamic System (PAAS). This design aims to minimize aerodynamic drag without compromising performance. (cyclingnews.com)
Aerodynamic Advancements
The PAAS technology strategically positions the tire’s widest point to optimize airflow between the tire and rim, enhancing the “sailing effect” at various yaw angles. Developed over 18 months using advanced computational fluid dynamics (CFD) tools from Pirelli’s motorsport divisions, the SL-R tire demonstrates a 2-watt aerodynamic gain at 45 km/h compared to its predecessor, the P Zero Race RS. In high-wind conditions, this improvement can reach up to 15 watts. (cyclingnews.com)
Enhanced Performance Features
The P Zero Race TLR SL-R features a lighter, more supple LiteCore 120 TPI casing, improving both rolling resistance and comfort while maintaining puncture protection. The tire utilizes the SmartEVO² compound, derived from Pirelli’s motorsport expertise, offering superior grip and handling on both dry and wet surfaces. (cyclingnews.com)
