Slick Tyres

On the sidewall of our racing tyres you can read the characteristic dimensions. For example: 325/680 - 18 C / D - d / C = Nominal section width [mm] / D = Nominal external diameter [mm] / 
d = Nominal rim fitting diameter [inch]

To ensure safe use, tyres should always be inflated above the recommended minimum inflation pressure threshold. Always contact your local Pirelli dealer or technical representatives for guidance on the main characteristics of the products and how to identify the correct operating conditions. To avoid unexpected pressure changes during your ride, we recommend using only dry air or nitrogen to inflate your tyres.

The range of our Dry tyres can be recognized by the letter D followed by the compound chosen from those available:
HH – SUPER-HARD / H – HARD / M – MEDIUM / S - SOFT / SS - SUPER-SOFT

The temperatures measured on the tread are an excellent indicator for understanding whether the compound is operating in its ideal range and for optimizing the setting parameters, such as suspension geometry and stiffness. When measuring the temperature on the surface of a tyre, the difference between the inside and the outside should be a maximum of 20 °C. The difference between the temperatures measured on the front and rear tyres should be a maximum of 25°C.
