RacingPirelli will go as soft as possible for back-to-back Sprint weekends, confirming the C3, C4 and C5 compounds for Miami and Montreal. The supplier will bring the same range to the Miami Grand Prix on May 1–3 at the Miami International Autodrome and to the Canadian Grand Prix on May 22–24 at Circuit Gilles Villeneuve, aiming to suit low-abrasion surfaces and open up more strategy.
Both events run the Sprint format, with Miami the second Sprint of the season and Montreal the third. That means more competitive laps and less practice, a mix that raises tire-management pressure across each weekend, according to Pirelli’s selection announcement.
For Miami, Pirelli said the very smooth asphalt and Florida heat point to thermal degradation rather than wear from the surface. That profile fits the softest trio, which should provide grip without the risk of the track grinding the rubber. Miami’s layout around the Hard Rock Stadium rewards traction out of slower corners and demands stability into heavy-braking zones, so teams will watch surface temperatures and cooling as the soft compounds come up to speed.
Montreal gets the same approach for different reasons. Pirelli explained the Circuit Gilles Villeneuve has historically low abrasiveness but asks for maximum grip under big stops, especially into the final chicane and the hairpin. “Thanks to a track surface that is not very abrasive and to provide adequate grip in areas where the cars are subjected to heavy deceleration,” Pirelli, Formula 1’s tire supplier, said in its selection announcement, outlining why C3, C4 and C5 suit Canada.
There is a change at the top end of the range this year. Pirelli noted that the C6 compound, which appeared in Canada last season, was dropped at the end of the year. C5 now stands as the softest available option for both races.
The timing adds another layer. Formula 1 returns after a roughly five-week break caused by race cancellations in the Middle East, with Miami restarting the campaign at the beginning of May. Two Sprint rounds in short order, paired with the softest compounds, should increase the chances of thermal degradation shaping strategy, especially in heat and under repeated heavy-braking. Pirelli presented the choice as aimed at strong grip and the potential for more strategy variation across both events in its announcement.
Teams now face condensed practice on Fridays to map out tire behavior, then must commit to setups that survive a Sprint and a Grand Prix. Expect pit windows to be more fluid and driver tire management to matter from the first competitive lap in Miami to the run to the Wall of Champions in Montreal.
