Pirelli’s Motorsport Head Details F1 Tyre Strategy, Wheel-Rim Innovation, and Future Challenges Through 2028.

Formula 1 is currently undergoing a profound technical evolution, impacting every facet of car design and performance. Central to this transformation is the intricate relationship between the car and its tyres, the sole points of contact with the track. To gain insight into these developments, Dario Marrafuschi, Pirelli’s Head of Motorsport, recently provided an extensive overview, addressing both the immediate challenges faced by teams and the strategic direction for tyre development towards the 2027 regulations and beyond.

Pirelli’s commitment to Formula 1 has been solidified with a recent extension of their supply agreement, now running through the 2028 season. This vote of confidence from the FIA and Formula 1 Management (FOM) underscores the Italian manufacturer’s enduring role in the sport. Marrafuschi affirmed Pirelli’s continuous presence in F1 since 2011, noting their historical ties dating back to the very first Grand Prix in 1950. "Our commitment to Formula 1, aside from having started in 1950… has been a constant presence over the last 15 years," Marrafuschi stated. "Since 2011, we have been a supplier, a technical partner, and a global partner for F1. Receiving this one-year extension certainly stands as a testament to our ongoing commitment and the reputation we have built over these years." He highlighted F1 as a highly technical environment driven by technology and innovation, but equally reliant on the trust fostered with all stakeholders, including the FIA, FOM, and the teams who receive tyres and engineering consultancy services during race weekends.

Looking further ahead, a new technical cycle has commenced, projected to continue until 2030. When asked about Pirelli’s aspirations beyond the 2028 agreement, Marrafuschi confirmed their willingness to discuss future partnerships should the FIA and Formula 1 express interest. He emphasized that as global and technical partners, Pirelli would respect the timing and requests of the sport’s governing bodies, just as they have consistently done in the past.

The current 2024 season has presented its own set of unique circumstances for tyre management. Notably, races at low-energy circuits like Monaco and Canada saw lap times quicker than Pirelli’s initial predictions. Marrafuschi clarified that these were largely isolated incidents. "The low-energy aspect is certainly a significant technical factor, but as far as those two races are concerned, I believe they were exceptional and isolated cases," he explained. He attributed this to a combination of factors: evolving track and asphalt conditions, ambient temperatures, and the rapid aerodynamic development by teams. Pirelli’s simulations, while robust, occasionally lag behind the very latest aerodynamic packages introduced by teams. These "marginal gains," accumulating tenths of a second, can lead to higher-than-expected performance. However, races like Silverstone, with track temperatures around 40-44 degrees Celsius and air temperatures near 25-26 degrees, saw performance align precisely with Pirelli’s design window, indicating that minor discrepancies are typically due to slight mismatches in data supply and forecasts.

A significant observation from the Monaco Grand Prix was the widespread adoption of an "extra preparation lap" by teams to bring tyres up to optimal temperature. This trend is a direct consequence of the 2024 cars generating less energy into the tyres. Marrafuschi detailed the contributing factors: a lower overall downforce level compared to the previous year, the effect of active aerodynamics reducing downforce on straights, and reduced heat transfer from brake discs to wheel rims due to increased energy recovery via electric motor regeneration. This collective impact results in a lower thermal regime and a different thermal balance for the tyres. The current specification tyres, redesigned for the season, feature different geometries and materials compared to their predecessors, contributing to this characteristic. Monaco, being a low-severity track, naturally exacerbates the warm-up phase. The recalibrated C5 compound, while essential for various circuits, necessitates a more deliberate warm-up procedure in such conditions.

The challenge, Marrafuschi clarified, lies primarily in achieving and maintaining the optimal tyre temperature across both axles, rather than merely keeping grip within a specific window. "It’s a matter of getting the tyre up to temperature, and I would also differentiate between the front and rear axles," he noted. Teams often expend significant effort during the out-lap to warm up both the front and rear axles into the correct operating window, with the front tyres generally requiring more attention.

Crucially, the open regulations concerning wheel-rim designs have emerged as a significant performance differentiator this season. While not always evident to the casual viewer, teams are actively innovating to manage operating pressures. Marrafuschi elaborated on how wheel-rim designs, featuring elements like hollow spokes or "pockets," are engineered to facilitate heat exchange with the brake ducts. This allows teams to precisely govern pressure build-up from starting pressures to stabilised running pressures. "We actually see differences among the various teams in who manages to… manage it differently," Marrafuschi explained. "For one team, the goal might be to heat it up, while for another team, it’s to cool it down, depending on the car’s balance. So, we see differences, and it is a significant performance lever." The ability to consistently control tyre pressures within the optimal window throughout a stint is a key factor in achieving consistent lap times, especially during long runs.

Pirelli has observed two distinct philosophies among teams regarding tyre temperatures and pressures. Some aim for lower pressures and cooler running conditions, typically associated with improved grip, while others deliberately seek higher temperatures to aid tyre warm-up. Marrafuschi explained that this isn’t simply a matter of efficiency, but rather a strategic choice influenced by the car’s inherent characteristics and race pace. "Generally speaking, running lower pressures is an advantage for grip," he stated. "However, depending on race pace or vehicle performance, some teams actually struggle to keep pressures low because, by going very fast, they put a lot of heat into the tyres, while other teams might face the exact opposite problem." Ultimately, the design of brake ducts, brake drums, and wheel rims provides teams with engineering levers to ensure their tyres operate within their optimal window.

Looking ahead to 2027, the prospect of an escalating "development war" in wheel-rim design has raised questions about potential FIA intervention. Marrafuschi emphasized that Pirelli is equipped to handle the current regulatory framework for wheel-rim changes. Any proposed changes are regulated, with the FIA being informed due to the unique "pairing" of the tyre, rim, and pressure sensor. Pirelli also handles the mounting of wet tyres onto rims for transport, which requires on-site changes if teams alter rim specifications. Therefore, any restriction on wheel-rim development would stem from reasons beyond Pirelli’s operational concerns.

Regarding the wider regulatory landscape, Marrafuschi confirmed ongoing communication between Pirelli, the FIA, FOM, and the teams concerning the 2026 technical cycle and potential downforce reductions for 2027 cars. He acknowledged that teams have exhibited an "exponential curve" in aerodynamic development, prompting the FIA to discuss adjustments to keep car performance within the intended design window for 2026/2027. This proactive approach ensures a sustainable package for all technical partners, as aerodynamics profoundly impact all vehicle parameters, including tyres. Pirelli works in advance on these topics, ensuring their tyre designs align with the evolving regulatory goals.

For the 2027 compounds, Pirelli is well into development, having completed baseline work on new material packages. Marrafuschi revealed that the range will continue to consist of five revised compounds, with no plans to introduce a C6. This decision was informed by observations from races like Monaco, where the C5 proved effective in generating exciting qualifying sessions, despite the need for an extra preparation lap. A C6, he argued, would likely be too soft for practical use across the majority of the calendar. The objective for 2027 is to recalibrate these five compounds to offer clear performance differentiation, proportional degradation, and more closely overlapping strategies in races. Marrafuschi cited instances like Barcelona and Austria where two- and three-stop strategies were similar, contrasting with Silverstone where one- and two-stop strategies were far apart. The goal is to create more strategic options for teams and drivers, fostering closer racing.

A recurring theme since the introduction of 18-inch tyres in 2022 has been the altered behaviour in the combined braking and turning phase. Marrafuschi attributed this to the reduced sidewall height of the 18-inch tyres, which results in a shorter contact patch. This physical change leads to a more sudden transition from grip to loss of grip, offering drivers less warning before the "snap." While work has been done to mitigate this, it remains a physiological characteristic of the tyre design. The narrower tyres introduced this season have subtly influenced this effect, though less dramatically than the initial 13-to-18-inch transition. He also addressed McLaren’s reported sensitivity to this phenomenon, suggesting it aligns with the unique characteristics and development path of their car, which might prioritize certain advantages while accepting trade-offs in other areas.

Marrafuschi also shed light on how driving styles interact with tyre behaviour. He offered an example of some drivers "saturating the front tyres" on corner entry with sharp steering inputs to stabilize the rear and progressively gain front grip. This style inevitably impacts tyre wear and temperatures. Pirelli’s data analysis across teams and sessions reveals distinct wear patterns influenced by both driving style and setup choices, such as understeer bias or camber adjustments. "That is exactly the beauty of the competition," Marrafuschi commented, highlighting Pirelli’s role in providing technical assistance to teams, offering insights into how their tyres perform with specific cars, setups, and driving techniques.

On the topic of wet weather tyres, the "super-intermediate" compound remains under active development. Marrafuschi confirmed that Pirelli has not abandoned this path, consistently evaluating innovative products for improvement. However, development has been slightly delayed due to the cancellation of an initial wet-weather test in Bahrain and the ongoing lack of wet races this season, which has prevented critical feedback on how current cars perform with existing wet compounds. While Pirelli is assessing opportunities to recover a wet testing day, Marrafuschi stated he could not confirm the super-intermediate’s readiness for 2027 homologation due to these setbacks. All wet-weather developments are shared with the FIA and F1 to ensure the best technologically available choice.

Finally, Marrafuschi addressed the logistical complexities of adding a potential replacement race to the calendar, particularly for a Middle Eastern venue. Such a proposition presents a significant challenge for Pirelli. The primary logistical bottlenecks are the Strait of Hormuz and the Houthi-controlled area off Yemen, which complicate cargo ship transit. Pirelli has mapped out various scenarios, including circumnavigating Africa, which would require approximately 15 weeks of lead time (around four months’ notice) for a transport of that scale. Alternative routes, such as through the Suez Canal and overland across Saudi Arabia, are being evaluated for viability and efficiency. Marrafuschi emphasized the inherent uncertainty, stating that in the worst-case scenario, 15-16 weeks would be needed, while the best-case might be around six weeks. He concluded that Pirelli operates within a vast F1 logistical ecosystem, and any new Grand Prix addition would only occur after a thorough assessment of all logistical feasibility.
