F1 Singapore GP 2026: Pirelli Reveals C3, C4 and C5 Tyre Strategy

Singapore, October 6, 2026: Formula 1 heads to the Marina Bay Street Circuit for the 2026 Singapore Grand Prix, with Pirelli selecting the C3, C4 and C5 compounds for the final Sprint weekend of the season. The C3 will serve as the Hard tyre, C4 as the Medium and C5 as the Soft, with Pirelli expecting the softer compound to play a potentially bigger role in the race than in previous years.

The Singapore Grand Prix will bring the long triple-header that began in Baku to an end, while also hosting the final F1 Sprint of the 2026 season.

The 4.940-kilometre Marina Bay circuit remains one of the most physically demanding venues on the Formula 1 calendar. The street circuit features 19 corners, close barriers and limited overtaking opportunities, while the changes made to the final sector in 2023 have made the lap faster and smoother.

Despite several straights, the circuit remains dominated by braking and traction zones, allowing modern Formula 1 power units to recover significant amounts of energy throughout the lap.

C3, C4 and C5 tyres selected for Singapore

Pirelli will bring the same tyre allocation used at last year’s Singapore Grand Prix:

• C3 – Hard
• C4 – Medium
• C5 – Soft

The Marina Bay circuit has medium-to-high surface roughness for a street circuit, with both macro- and micro-roughness contributing to tyre demands. With no resurfacing work carried out since last year’s event, Pirelli expects track characteristics to remain broadly similar, although surface roughness could be slightly higher.

Track evolution is expected to be significant throughout the weekend as more rubber is laid down on the circuit.

The Sprint format could also influence tyre usage, with teams having additional opportunities to assess the performance of the softer compounds before Sunday’s Grand Prix.

C5 Soft tyre could play a bigger role

While the Hard and Medium compounds are expected to remain important for Sunday’s race, Pirelli believes the C5 Soft could receive greater consideration this year.

The softest compound in Pirelli’s range has shown strong performance at races such as Budapest, Monza and Baku, where it delivered good pace without suffering excessive degradation.

The C5 also provides drivers with additional grip and confidence, characteristics that could prove particularly valuable at Marina Bay as the track evolves throughout the weekend.

Pirelli also points to the current generation of Formula 1 cars as a factor behind the greater potential usability of the soft compound. Improved aerodynamic load, more effective temperature management and the formulation of the latest-generation tyres allow softer compounds to remain competitive for longer.

As a result, teams could potentially use the C5 during Saturday’s Sprint, while its presence in the main race could also be more extensive than in previous Singapore Grands Prix.

One-stop strategy remains favourite

From a strategic perspective, the one-stop strategy remains the preferred option for the Singapore Grand Prix.

The relatively high time loss associated with a pit stop, combined with the frequent possibility of Safety Cars or other neutralisations at Marina Bay, makes minimising pit stops particularly valuable.

Pirelli expects the Hard and Medium tyres to be the main race compounds, although the improved performance and durability of the C5 could give teams another viable option.

Rear-axle performance will be one of the key factors affecting tyre degradation, particularly through the numerous traction zones around the circuit. However, Pirelli does not expect graining or tyre wear to become major limiting factors.

Heat and rain add to Singapore challenge

The Singapore Grand Prix is run at night, but temperatures remain high. Track temperatures are expected to range between 30°C and 35°C.

Despite the heat, Pirelli does not anticipate significant overheating problems, with the tyres expected to operate within their normal working window.

The circuit’s equatorial climate introduces another variable, however. Intermittent rainfall is common in Singapore and can dramatically alter grip levels between sessions.

A wet or partially wet track could therefore have a major influence on tyre choice and setup, particularly during the Sprint weekend when teams have limited opportunities to gather data.

Singapore Grand Prix 2026 marks 17th edition

The 2026 Singapore Grand Prix will be the 17th edition of the event.

The race has been held continuously since 2008, apart from the 2020 and 2021 editions, which were cancelled because of the COVID-19 pandemic.

Sebastian Vettel remains the most successful driver at the Marina Bay circuit with five victories, while Lewis Hamilton has four wins. Both drivers have also taken four pole positions at the Singapore Grand Prix.

Among constructors, Mercedes leads the way with five victories at Marina Bay.

Pirelli Singapore GP podium cap inspired by orchids

The podium ceremony will feature a special Pirelli cap inspired by the orchid, a flower strongly associated with Singapore.

The design reflects the orchid’s ability to thrive in heat, humidity and heavy rainfall, symbolising resilience in challenging conditions.

The special-edition Pirelli Podium Cap has been produced by Pirelli Design and designed by Denis Dekovic.

With the Singapore Grand Prix bringing the 2026 triple-header to a close and featuring the final Sprint of the season, tyre strategy could once again become a decisive factor at Marina Bay. While the C3 and C4 remain the expected reference compounds for Sunday’s race, the improved performance of the C5 could encourage teams to take a more aggressive approach with the Soft tyre throughout the weekend.
