A few weeks ago it was anticipated some of the aerodynamic and technical changes that will be applied in Formula 1 from next year. Among these modifications, one of the most important has to do with the tires: for the first time since the 1960s, the now classic compact and very wide tires with a prominent sidewall that characterized the category for tires and tires of 18 inches that look a little more like those used in street supercars.

As in recent years, Pirelli will continue to be the tire supplier. Together with the presentation of the 2022 car, it unveiled the new P Zero F1, which has the same tread width as before (305 millimeters at the front and 405 millimeters at the rear), but a slightly larger overall diameter, which goes from 660 millimeters to 720 millimeters. The most significant change is the reduction of the flank, now quite similar to that of a conventional vehicle.

According to the Italian company, this new profile will change the behavior of the cars on the track, making them more precise when changing direction. In the tests carried out so far, both in the dry and in the wet, the feedback from the drivers has been positive and the new tires will contribute to making the races even more competitive, with cars less sensitive to aerodynamic turbulence while following each other. The lower sidewall also means that the tire will flex less, which means it will have less impact on the overall aerodynamics of the vehicle. All of this should favor close races.

The compounds on the 18-inch tires will also be completely new, to ensure maximum consistency and less overheating. There will be five compound grades available for the championship, of which three will be chosen for each race weekend, as is currently the case.

A particularity that reflects Pirelli’s commitment to the category is that, going from 13 to 18 inches, it is the only tire manufacturer that has competed in Formula 1 with all the wheel sizes that were part of its history. Its beginnings date back to 1950 with the first victories and titles with Alfa Romeo, Ferrari and Maserati.
