Pirelli to Validate Hamilton's Wet Tyre Test Data at Magny-Cours

Lewis Hamilton’s recent two-day wet-weather tyre test at Ferrari’s Fiorano circuit gave Pirelli a rare opportunity to gather data on intermediate and full wet prototypes. But with Fiorano’s unique layout limiting the applicability of results, Pirelli is now planning a follow-up test at Magny-Cours in mid-May to validate its findings.

Why it matters:

Pirelli’s full wet tyre has been heavily criticized by drivers in recent years, often being used only behind the safety car before switching to intermediates. Improving the wet tyre is crucial for safety and racing in wet conditions. Gathering reliable data across different circuits is essential to develop a tyre that works universally.

The details:

• Hamilton completed the test during the April break, testing several prototypes including new tread patterns.
• A planned test in Bahrain was abandoned in March due to the outbreak of military conflict, preventing crucial data collection on a high-severity circuit.
• Pirelli motorsport boss Mario Isola emphasized that Fiorano’s unique characteristics mean results cannot be directly replicated elsewhere.
• The Magny-Cours test will allow Pirelli to compare Hamilton’s feedback and data with fresh results from a different track layout.
• Isola noted the difficulty of developing a single tyre that performs well across all circuits, making cross-validation vital.

Looking ahead:

The Magny-Cours test will help Pirelli finalize specifications for the wet and intermediate tyres. With the full wet tyre currently a weak point in the F1 package, any improvements could significantly impact race strategy and safety in future wet rounds.
