F1TECH: What compounds will drivers have at their disposal at Silverstone?

Silverstone, the cradle of motorsport and host of the world’s first Formula 1 World Championship race, will once again test the limits of tyre performance as Pirelli prepares for the 77th edition of the British Grand Prix.

The event marks the first of two rounds this season in which the Italian manufacturer serves as title sponsor, linking its brand to the championship’s longest‑running and most historic races: the British and Italian Grands Prix. Both have appeared on the calendar every year since 1950, retaining their original names and cementing their status as pillars of Formula 1 tradition.

Pirelli’s connection to Silverstone dates back to the very beginning. The inaugural World Championship race in 1950 was won by Giuseppe Farina on Pirelli Stella Bianca tyres, a milestone that now frames the company’s return as title sponsor for the 2026 edition. This weekend also marks Pirelli’s 518th Grand Prix appearance.

Silverstone’s 5.891‑kilometre layout, last significantly revised in 2010, remains one of the most demanding circuits for tyres. Its 18 corners — 10 right‑handers and eight left‑handers — generate extreme lateral forces, particularly through the iconic Maggotts‑Becketts‑Chapel sequence.

Combined with long straights and rapid direction changes, the track pushes tyres to their structural limits. Lewis Hamilton, the most successful driver at Silverstone, famously likened the experience to flying a fighter jet.

Peak accelerations exceed 5g in several sections, comparable to Suzuka and Spa. The front axle absorbs the brunt of the load, with the left‑front tyre especially vulnerable due to the predominance of right‑hand corners.

Despite the severity, the asphalt itself is not abrasive. Silverstone’s surface has relatively low roughness and offers strong baseline grip thanks to year‑round use across multiple racing categories. This combination — high energy, low abrasion — shapes Pirelli’s compound selection.

For 2026, Pirelli has opted for the hardest trio in its range: C1 (Hard), C2 (Medium), and C3 (Soft). The choice reflects the circuit’s high‑speed nature and the need to control degradation over long stints.

C1 provides maximum structural robustness and is expected to feature prominently in Friday’s running, particularly in FP1 due to the Sprint format. C2 offers a balance of grip and durability and is likely to be central to race strategy. In addition, C3, the softest of the three, has shown light graining in previous years but remains a viable option for qualifying and shorter stints.

Given the circuit’s characteristics and historical data, Pirelli anticipates a one‑stop strategy for Sunday’s Grand Prix, with teams favouring the C2–C3 combination. The harder compounds have consistently demonstrated strong mechanical stability, while the C3’s graining tendencies are typically manageable as the track rubbers in.

The British weather factor
Silverstone’s weather remains the great variable. Rain has affected the last two British Grands Prix, forcing drivers onto Cinturato Intermediate tyres during key phases of the race.

Even in midsummer, showers can arrive suddenly, and cloud cover can dramatically alter track temperature and grip levels. Teams will therefore keep wet‑weather sets close at hand, especially given the Sprint format’s compressed preparation window.

Following the Grand Prix, Pirelli will stay at Silverstone for two days of development testing focused on the 2027 dry‑weather tyre range. Mercedes and Williams will support the programme, providing data on construction behaviour, compound evolution and performance consistency under high‑energy cornering loads.

Looking back: 2025
Last year’s British Grand Prix showcased the circuit’s unpredictability. Variable conditions dominated the first half of the race, with all drivers starting the formation lap on intermediates before several switched to slicks.

Rain returned before the start, forcing a universal move back to intermediates. In the closing stages, the track dried again, prompting a final switch to slicks — mostly Mediums and Softs — for the run to the flag.
