FIA Issues Warning to Two F1 Teams Over Tire Temperature Infringement in Las Vegas

The FIA has warned two Formula 1 teams in Las Vegas for exceeding the permitted tire temperature limit during FP3, as reported by The Race. While no immediate penalties were given, the governing body made it clear that any similar infringement in official sessions could lead to disqualification, emphasizing the strict adherence required, especially in cold track conditions.

The FIA has reportedly warned two Formula 1 teams in Las Vegas for using tricks to get their tires warmer than permitted during FP3. While no penalties were issued, the governing body made it clear that similar infringements in official sessions could lead to disqualification.

Why it matters:

Formula 1's strict tire temperature regulations are in place to ensure fair competition and driver safety. With the cold conditions in Las Vegas posing a unique challenge for teams to get tires into their optimal operating window, any attempt to circumvent the rules, even in practice, is a significant breach of sporting integrity and could grant an unfair advantage.

The Details:

  • Cold Conditions Challenge: The unusually low ambient and track temperatures in Las Vegas have made it difficult for teams to bring their Pirelli slick tires up to the required operating temperature.
  • Pre-heating Regulations: Teams are allowed to pre-heat slick tires to a maximum of 70 degrees Celsius for two hours before a session using tire blankets. Exceeding this limit is strictly forbidden.
  • FIA Monitoring: Stewards use heat guns to rigorously check tire temperatures, ensuring compliance with the 70-degree limit.
  • FP3 Infringement: During the final free practice session, two unnamed teams were found to have tires warmer than the permitted 70 degrees Celsius.
  • Official Warning: The FIA informed the teams of their findings and issued a stern warning, instructing them to adhere to the allowed temperature limits for qualifying and the Grand Prix. The teams were required to cool down the overheated tires or switch to a new set to avoid official reporting to the stewards.

What's next:

This warning serves as a clear message that the FIA is actively monitoring compliance with technical regulations, especially concerning tires in challenging conditions. Any repeat offense during qualifying or the race itself will likely result in severe penalties, potentially including disqualification, as the governing body maintains a strict stance on fair play and technical adherence.
