Pirelli will bring its three softest Formula 1 tyre compounds to the 2026 Brazilian Grand Prix at Interlagos, with tyre degradation expected to be one of the main technical challenges facing Ferrari and its rivals. The Italian manufacturer has selected the C3 as the Hard, C4 as the Medium and C5 as the Soft, introducing a softer allocation than last year for a weekend that could be complicated by resurfaced sections of the circuit and unpredictable weather conditions.
The São Paulo Grand Prix, held at the José Carlos Pace circuit, marks the conclusion of Formula 1’s three consecutive races in the Americas. Following the events in the United States and Mexico, teams now face a different challenge at one of the championship’s most distinctive venues, where managing tyre performance over longer stints could prove decisive.
Pirelli confirms softest tyre compounds for 2026 Brazilian GP
For the final event of the American triple-header, Pirelli has nominated the softest available selection in its Formula 1 range: C3 Hard, C4 Medium and C5 Soft. The choice represents a step towards softer compounds compared with the 2025 São Paulo Grand Prix, which was held under the Sprint weekend format.
The change could create additional strategic considerations, particularly if the softer tyres experience significant degradation during longer runs. Finding the right balance between outright performance and tyre preservation will be essential as teams prepare for Sunday’s race.
Pirelli’s approach follows its broader 2026 tyre compound selections for Austin, Mexico City and São Paulo, with Interlagos completing the sequence of three consecutive Formula 1 events in the Americas.
New Interlagos asphalt creates uncertainty over grip and tyre wear
Beyond the softer Pirelli compounds, the Brazilian circuit has undergone changes since last season. Resurfacing work has been carried out in two sections: between Turns 3 and 5 and between Turns 8 and 9.
These newly resurfaced areas could affect the level of grip available to drivers and the evolution of track conditions throughout the weekend. Their influence may be particularly important over longer runs, where differences in tyre wear and degradation become more apparent.
Unlike last year’s Sprint event, the 2026 weekend features three free practice sessions. This gives Ferrari, Mercedes, McLaren, Red Bull and the other teams additional opportunities to evaluate how the circuit evolves and understand the behaviour of the new asphalt.
The sessions will be especially useful for assessing whether the resurfaced sections influence tyre degradation and wear, allowing teams to refine their race preparations before qualifying and the Grand Prix.

Why tyre degradation could be decisive at Interlagos
Tyre degradation was already one of the most important technical factors at the São Paulo Grand Prix twelve months ago.
Although graining was less severe than initially expected, the C2 compound, which was selected as the Hard tyre in 2025, showed a tendency to slide. Meanwhile, the C3 and C4 compounds experienced significant degradation, although both still allowed drivers to complete competitive stints.
On that occasion, the most effective race strategy proved to be a two-stop approach.
With Pirelli introducing an even softer selection this year, the challenge of managing tyre performance over longer distances will once again be central to the teams’ preparations. Interlagos does not place extreme demands on tyres in terms of overall loading. The circuit features lateral forces that are generally around the average for Formula 1, combining several high-speed corners with significant straights.
Importantly, those loads are distributed relatively evenly between the front and rear axles, rather than concentrating excessive stress on one end of the car.
Nevertheless, the characteristics of the circuit create a demanding compromise between maintaining competitive lap times and preventing excessive tyre degradation.
Brazilian GP tyre strategy: Teams must balance pace and degradation
The numerous overtaking opportunities provided by Interlagos give teams a degree of strategic flexibility. Unlike circuits where passing is particularly difficult, the Brazilian venue offers several chances to recover positions, potentially allowing teams to consider different approaches to pit-stop timing.
However, controlling degradation has traditionally remained the key to maximising race performance at São Paulo.
The challenge will be to identify the ideal compromise between outright lap speed and preserving tyre performance across longer stints. Teams will use practice to evaluate which compounds offer the most effective balance and how quickly their performance declines.
These differences can be explored through the ScuderiaFans F1 Tyre and Stint Analysis, which provides detailed information on compound usage, stint lengths and tyre strategies across Formula 1 races.
For Ferrari and its competitors, understanding the behaviour of the softer Pirelli compounds could be an important factor in determining the most effective race strategy.
Rain and changing temperatures add another challenge for the Brazilian GP
Weather conditions represent another major uncertainty at Interlagos. Due in part to its position on the Formula 1 calendar, the Brazilian circuit has frequently hosted races affected by rain and substantial temperature fluctuations.
These conditions can complicate tyre selection and make it more difficult for teams to predict how the track will behave during the Grand Prix. As a result, Pirelli’s Intermediate and Full Wet compounds could also come into play during the 2026 Brazilian Grand Prix.
Between the softer tyre allocation, resurfaced sections and the possibility of changing weather, tyre management is set to be one of the defining technical considerations of the Interlagos weekend. The three practice sessions will provide teams with their first opportunity to understand how those variables interact before the battle for the best possible race strategy begins.
