Benefits of PIRELLI P7 Classic Tires

Any modern tire would be unsuitable for the chassis of a 1970s performance car, producing handling characteristics that were not intended for the vehicle, and ultimately blocking the cars potential. Preserving the authenticity of classic cars is a priority for Pirelli, which led them to develop the PIRELLI CINTURATO ™ P7 with a tire carcass that faithfully replicates the handling and steering feedback of period tires.
