Pirelli Confirms Softest Tyre Compounds for Miami and Canadian Grands Prix

Pirelli will run its softest C3‑C5 tyres at Miami and Canadian GP, citing smooth surfaces and high temperatures that cause thermal wear. The smooth asphalt at the Miami International Autodrome and the low‑abrasion track in Montreal favour the soft compounds for grip and thermal degradation. After a limited tyre map in China and the second Australian round, the full soft range returns for the next two events.

Why it matters:

• Higher degradation in Miami’s heat forces teams to rethink pit‑stop windows.
• Soft compounds boost qualifying pace, narrowing the gap to front‑runners.
• A full soft range gives engineers more wear data for the second half of the season.
• More grip on low‑abrasion surfaces can shift race strategy, increasing the number of stops.

The details:

• Compounds: C3 (hardest soft), C4 (mid‑soft), C5 (softest). All available for practice, qualifying and race.
• Track influence: Miami’s smooth surface leads to thermal wear; Montreal’s low‑abrasion asphalt favours soft compounds for better braking grip.
• Last year: The C6 was used in Canada before being dropped; it will not appear this season.
• Recent history: Soft tyres debuted in Australia, then were reduced for China and the second Australian race, showing Pirelli’s flexible allocation.

What's next:

• The plan will be tested in Miami’s May race, with data feeding into the Canadian weekend.
• If tyre wear stays manageable, Pirelli could extend the soft range to other low‑abrasion circuits.
• Teams will tweak setups and fuel loads to maximise grip while managing degradation.
