Pirelli Set for 2026 C6 Tyre Overhaul After Verstappen’s Fierce F1 Critique

Pirelli will revise its softest C6 tyre for 2026 after sustained criticism led by Max Verstappen. The compound is withdrawn for the rest of 2025.

The C6 debuts in 2025 as a street‑circuit option. It aims to add a softer step below the C5, offering extra grip and strategic flexibility.

Early usage exposes issues. In Azerbaijan, many drivers qualify on mediums rather than risk the C6’s behavior.

Verstappen calls the tyre unhelpful and “very tricky,” citing Monaco, Imola, and Montreal. He even questions whether Pirelli should skip the compound entirely.

Motorsport chief Mario Isola acknowledges the remarks and plans to speak with Verstappen. He stresses there is no urgency.

The C6 is initially slated for Singapore and Las Vegas. Pirelli removes it, fearing graining from high energy in Singapore and low temperatures in Las Vegas.

Isola explains that softer compounds typically help on cold tracks. However, the C6’s lower mechanical resistance increases early‑phase graining risk before the tyre fully warms.

Graining damages the surface and reduces grip. Avoiding that outcome drives Pirelli’s conservative nominations.

There is one upside. The C6 adds uncertainty to qualifying, with some drivers trialing it against the C5.

Performance data shows the C6 is only a couple of tenths faster than the C5. The expected delta is larger.

Drivers also find the C6 harder to manage. Isola describes it as “more peaky or unpredictable,” limiting consistent extraction across runs.

For 2026, Pirelli will re‑work the C6 to create a clearer gap to the C5. The current overlap undermines compound differentiation and strategy variety.

All compounds will change under new construction and regulations. That provides a clean slate for revisions across the range.

Verstappen’s feedback aligns with Pirelli’s internal review. The goal is a softer tyre that remains predictable and durable for qualifying and short stints.

The broader aim is a properly spaced portfolio that teams trust. That should improve weekend flow and reduce setup compromises driven by tyre uncertainty.

Fans comparing demands between F1 and NASCAR can see contrasts in compound strategy and duty cycles across disciplines.
