Overview

  • McLaren has won five of the first six races in the 2025 F1 season, including a dominant one-two finish at the Miami Grand Prix.
  • Red Bull has suggested McLaren may be using banned water-cooling methods for their rear tyres, a claim McLaren dismisses as unfounded.
  • McLaren CEO Zak Brown mocked the allegations during the Miami GP weekend by drinking from a bottle labeled 'Tire Water' and challenged rivals to file formal protests if they believe rules are being broken.
  • The FIA and tyre supplier Pirelli maintain that any illegal tyre-cooling methods would be easily detectable under current inspection protocols.
  • Mercedes team principal Toto Wolff defended McLaren's tyre management as legitimate and attributed their success to strong technical development starting with updates introduced two years ago.
