Pirelli has created a bespoke P Zero for the Ferrari Monza SP1 and SP2.
The 21-inch tires, a first for Ferrari, were developed with stiffness, comfort and performance in mind. Instead of the traditional reinforced textiles to reduce weight, the bead area was redesigned to maintain lateral rigidity while minimizing weight, which saved about 2 1/2 pounds or 1.2 kilograms.
The Pirelli P Zero tire sizes for the Ferrari Monza are 275/30 R21 at the front and 315/30 R21 at the back.
The relationship between Pirelli and Ferrari has endured for decades, going back to when the Prancing Horse made its debut. The Ferrari 500 with which Alberto Ascari won two consecutive Formula 1 titles in the 1950s, as well as the Ferrari 375 Plus that triumphed at the 1954 Le Mans 24 Hours, used Pirelli tires. One of the most important collaborations between the two Italian firms was for the legendary F40 in 1987. For the first time, Pirelli created a P Zero that was specifically designed for the V8 biturbo from Maranello, paving the way for a whole family of tailor-made tires for road cars. The majority of the fastest Ferraris have used Pirelli as original equipment, including the F12TDF, LaFerrari and FXX- K among many others.
