Key Highlights
- Pirelli has designated the C3 (Hard), C4 (Medium), and C5 (Soft) compounds for Round 17 at the Marina Bay Street Circuit.
- Singapore is hosting an F1 Sprint for the first time, reducing overall weekend allocations from 13 down to 12 slick sets per driver.
- While a one-stop strategy featuring Hard and Medium tyres remains favored, Pirelli anticipates elevated usage of the C5 Soft across the weekend and potentially on Sunday.
Following Max Verstappen securing his initial win of the season at the Bahrain Grand Prix, the Formula 1 grid turns its attention to the grueling physical and mechanical demands of the Marina Bay Street Circuit. Official tyre supplier Pirelli has officially locked in the dry-weather allocations for Round 17 in Singapore, once again opting for the softest range in its catalogue: the C3 as the White hard, the C4 as the Yellow medium, and the C5 as the Red soft.
Sprint Format Debuts at Marina Bay with Adjusted Tyre Allocations
The upcoming Grand Prix weekend brings an added strategic twist, as Singapore will stage an F1 Sprint event for the first time in its history. Because of the revised weekend timetable, team strategists must navigate altered operational rules that limit their slick allocations to 12 total sets per driver rather than the customary 13 provided during standard Grand Prix weekends.
Under the mandated Sprint technical regulations, each competitor receives two sets of the C3 hard compound, four sets of the C4 medium compound, and six sets of the C5 soft compound. In addition to the dry-weather slicks, Pirelli supplies six sets of green intermediate tyres and three sets of blue full wet tyres to accommodate any equatorial storms.
Track Dynamics, Climate, and Surface Challenges
Pirelli highlighted the evolving physical traits of the venue in its comprehensive technical outlook for the round:
“The 4.940-kilometre track features the typical characteristics of a street circuit, with barriers close to the racing line and limited overtaking opportunities,” reads Pirelli’s weekend preview. “However, the changes introduced in 2023 to the third sector increased the number of high-speed sections, making the lap smoother and faster than in the past. Despite the presence of some straights, the circuit remains defined by numerous braking and traction phases thanks to its 19 corners, allowing modern power units to recover energy throughout the lap.
“Marina Bay has a medium-to-high level of surface roughness for a street circuit, both in terms of macro- and micro-roughness. As no resurfacing work has been carried out, values are expected to be broadly in line with last season’s, if not slightly higher. Track evolution will be significant over the course of the weekend. Intermittent rainfall, typical of the equatorial climate, will also influence grip levels and can alter conditions from one session to the next.
“As is well known, the race takes place at night, with track temperatures ranging between 30 and 35C. Under these conditions, the tyres tend to operate within their working window without any particular overheating concerns. Mechanical stress is not especially high and the expected degradation will mainly be linked to the normal performance drop-off of the rear axle during traction phases. Graining and wear are also not expected to become limiting factors in race management.

Potential Shift Toward the C5 Soft Tyre in Strategic Battles
Because the tight pit lane layout imposes significant time loss during stops, coupled with a historically high probability of Safety Car interventions, engineers traditionally gravitate toward a single-stop plan. Nevertheless, Pirelli suggests that recent real-world data and ground-effect car traits might push teams to expand their reliance on the softest rubber available:
“For these reasons, from a strategic perspective Singapore remains one of the races in which a one-stop strategy is the preferred option for teams, also considering the time lost in the pit lane and the frequent likelihood of neutralisations. While Hard and Medium are once again expected to be the reference compounds for the race, this year the Soft could receive greater consideration on Sunday from more than one team.”The softest compound in the range has demonstrated at Budapest, Monza and Baku, where it was used, that it allows drivers to maintain a strong pace thanks to limited degradation, while also offering an advantage in terms of grip and confidence behind the wheel. These characteristics could prove even more valuable on a circuit such as Singapore, which is also known for its significant track evolution.
“The latest-generation cars also appear to make better use of the softer compounds. Aerodynamic load, more effective temperature management and the formulation of the current compounds allow the softer end of the range to be used for longer and more competitive stints than in the past. With this in mind, it would come as no surprise to see the red-sidewalled tyre used in Saturday’s Sprint or, more generally, to witness more extensive use of the C5 throughout the weekend, encouraged by the Sprint format itself.”

Why This Matters
The introduction of the Sprint format to a tight street circuit fundamentally alters team preparation. With only one practice session before competitive sessions commence, squads will have far less time to test race pace across different fuel loads on an evolving track surface. Furthermore, if the C5 Soft proves capable of longer stints under high aerodynamic loads—as observed at tracks like Monza and Baku—it opens up tactical variance against the traditional Medium-to-Hard one-stop strategy, making pit wall execution and Safety Car timing even more decisive in the championship fight.
Frequently Asked Questions
Which tyre compounds are allocated for the Singapore Grand Prix?
Pirelli has brought its softest selection: the C3 as the Hard compound, the C4 as the Medium compound, and the C5 as the Soft compound.
How does the Sprint format affect tyre allocation for the weekend?
Under Sprint weekend rules, drivers receive 12 sets of dry-weather tyres instead of the usual 13, broken down into two sets of Hard, four sets of Medium, and six sets of Soft tyres, alongside their allocations of intermediates and wets.
Will teams be forced into a multi-stop strategy?
A one-stop strategy remains the baseline plan due to severe pit lane time loss and high safety car likelihood. However, Pirelli notes that improved soft-compound longevity on modern cars means the C5 could see competitive use alongside the Hard and Medium compounds.
