PAAS

PAAS is Pirelli’s advanced aerodynamic technology, developed through CFD analysis and wind‑tunnel testing to increase the efficiency of the tyre+wheel system. Its patent‑pending profile creates a seamless transition between tyre and rim, keeping airflow attached longer, reducing flow separation, and maximizing the sailing effect for lower drag

Designed for modern wide rims, PAAS delivers stable airflow, measurable aerodynamic gains, and consistent performance over time, even as the tyre wears. The result is a faster, more efficient and more stable system with an ideal balance of aerodynamics, grip, comfort and rolling resistance.
