In F1, Pirelli’s tire improvement has by no means stopped, regardless of the premier motorsport class having chosen a sole provider for a number of years now. Quite a few modifications to technical rules have required the Italian producer to remain in keeping with the evolving framework, whereas additionally striving to satisfy the groups’ wants. In a number of circumstances, the staff led by Mario Isola has needed to depend on simulations for tire design.
This occurred between 2016 and 2021 and continues to be the case as one other regulatory revolution approaches for F1 vehicles. Steady collaboration with the groups is essential for Pirelli to develop and produce tires suited to an ever-evolving platform. This platform refers to F1 vehicles, which, beneath regulatory continuity, change into more and more environment friendly because of the engineers’ work targeted on producing extra downforce to maximise automobile efficiency.
This pattern is clear when evaluating knowledge from 2023 to the earlier season. The common time for pole positions (in dry circumstances) decreased by eight-tenths of a second final season, whereas the common quickest race lap dropped by six-tenths. The tire provider acquired new simulations from groups on the finish of November, used to estimate potential additional lap time positive factors for 2025, together with insights from the post-season check in Abu Dhabi, following the ultimate race of the earlier championship.
Coming into the fourth (and ultimate) 12 months of regulatory continuity, efficiency enhancements are anticipated to gradual. Nonetheless, Pirelli’s chief engineer, Simone Berra, cautions that simulations will not be definitive: “We’ve seen very excessive hundreds from two or three groups,” he experiences. “Often, we obtain simulations mid-season and on the finish of the season. No one anticipated these sorts of hundreds. We thought they’d reached peak efficiency ranges, however there’s nonetheless extra to achieve. It’s all very attention-grabbing.”
Though 2025 would be the final season for this technology of tires, Pirelli doesn’t imagine groups will gradual their improvement efforts. The Italian tire provider has demonstrated glorious adaptability prior to now to efficiency ranges that differed considerably from these projected in simulations. For instance, final 12 months Pirelli launched a brand new tire building mid-season at the British Grand Prix, designed to accommodate increased speeds and hundreds in comparison with pre-season check knowledge.
In parallel with monitoring merchandise for the present season, Pirelli is growing new tires for the 2026 vehicles. These will stay 18 inches however will likely be narrower than the present ones to cut back the rolling resistance of future autos. It is a vital problem, on condition that monitor exams will likely be much less dependable as a result of the groups have offered and can present vehicles constructed beneath the present rules, modified to approximate the habits of the subsequent technology of vehicles.
As prior to now, Pirelli will undoubtedly rely closely on theoretical modeling and the assist groups present by means of their simulations. Having a 2026 mannequin outfitted with the brand new tires for wind tunnel testing can be immensely useful. Nonetheless, the FIA has not thought-about this selection.
The Italian firm continues to show its functionality as F1’s sole tire provider, with a contract presently extending by means of 2027. Moreover, the Milanese agency provides tires for the F2 and F3 championships.
