F1 teams have been warned about employing tyre temperature tricks at the 2025 Las Vegas GP, after some were caught with rubber that had been heated above the legal limit
At the 2025 Las Vegas Grand Prix, Formula 1 teams have received a warning against using tire temperature tricks, as some were caught with excessively heated rubber in final practice. The unique challenges of the Las Vegas track make generating tire temperature a crucial aspect for teams due to cool conditions and difficulty in achieving optimal tire heat. F1 regulations strictly limit the temperature and duration for which teams can heat their tires, with slick rubber allowed to reach 70C for a maximum of two hours before a session. The FIA conducts tire temperature checks using a heat gun on the tire tread to ensure compliance with regulations, as teams were caught exceeding the 70C limit during final practice. Teams found with overheated tires were alerted by the FIA and had to cool down the tires or switch to a new set to avoid regulatory breaches. The identity of the teams surpassing the temperature limit was not disclosed, but the FIA remains vigilant for potential infractions during the race weekend. Any team using tires above the 70C limit in a competitive session risks penalties, including disqualification for technical violations, as the FIA maintains a strict stance on tire temperature regulations in Las Vegas.
