With the 2025 F1 season slowly approaching its ultimate leg, F1Technical’s senior author Balazs Szabo explains how the game’s sole tyre provider, Pirelli inflate tyres.
Pirelli has been the only tyre provider in Method One since 2011 following Bridgestone’s determination to withdraw from the function on the finish of the 2010 season.
The Italian producer beforehand competed in Method One from 1950 to 1958, 1981–1986 and 1989–1991. Along with his function in Method One as sole tyre provider, Pirelli additionally provides tyres for the FIA Method 2 Championship, FIA Method 3 Championship and F1 Academy, that type the feeder sequence to Method One.
How does Pirelli inflate the tyres?
Earlier than the weekend, Pirelli inflates the tyres with compressed air, utilizing a particular machine to take away moisture. Then, within the becoming space the place all Pirelli tyres for the occasion are fitted to and stripped from the wheel rims provided by the groups, particular machines pump them as much as 60 psi to verify that they’re appropriately seated on the edges.
Then, the strain is lowered to 45 psi earlier than the tyres are collected by the groups. They will select whether or not to maintain the dried compressed air or to switch it with nitrogen, an inert, non-flammable fuel that’s much less permeable than oxygen. The usage of some other fuel or combination of gases is forbidden within the laws.
At every occasion, Pirelli states a compulsory minimal strain to be set initially, in addition to goal operating pressures that should be met for security causes.
For instance, on the opening day at July’s Hungarian Grand Prix, the minimal beginning pressures had been set at 22 psi on the entrance axle and 20 on the rear. On the finish of every session, the laws permit for the minimal strain to be adjusted to a brand new necessary strain for the next session.
