Pirelli said it was supplying special 21 inch tyres to Ferrari starts for the limited edition Monza SP1 and SP2.
The tyre maker developed a customised P Zero for the cars. This choice of 21-inch, for the first time in Ferrari's history, presented engineers with the challenge of offering the usual levels of stiffness, comfort and performance despite the record size.

The tyres also had to play a part in keeping weight to a minimum on the new car. To achieve this, instead of the traditional reinforced textiles, the bead area was redesigned to maintain lateral rigidity while minimising weight: this saved 1.2kg. The sizes are 275/30 R21 at the front and 315/30 R21 at the back.
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 car, paving the way for a whole family of tailor-made tyres for road cars. The majority of the fastest Ferraris have used Pirelli as original equipment, including the F12TDF, LaFerrari and FXX-K.
