Pirelli Motosport Tyres

P Zero™ Trofeo R has a stiff construction thus it does not necessarily need extra pressure to deliver performance. In fact they are designed to run at pressures around 2.2 bar (when hot), although the exact optimal pressure depends on the vehicle type.

The operating pressure reached when the tyre is fully warmed at working temperature, is critical for understanding the vehicle set-up.

Note that the pressure difference between “hot” and “cold” can be significant, typically around 0.5 bar.
