In the already tense climate of the Interlagos paddock, a new rumor emerges that is causing discussion. This time, the accused is McLaren, while Red Bull raises the stakes with a suspicion that sounds almost unbelievable: Woking's rivals are said to be using a secret trick to cool their tyres by putting water inside them. The news, launched by the prestigious Car engine and sport, has sparked reactions and curiosity. We will see if the FIA will investigate further by opening a new “case”.
The new chapter of the McLaren-Red Bull feud: water in tires
It seems that the rivalry between Red Bull and McLaren knows no respite. Already during the Austin weekend, Red Bull had been at the center of controversy for a system of adjustment of the car's floor with the T-Tray, which McLaren considered too “flexible” and easily maneuverable. A response to the case of flexible wings, which emerged in Baku. But there would be more. At Interlagos Red Bull seems to have returned to the attack again, pointing the finger at McLaren. The suspicion is that it may have found a way to insert small quantities of water into the tires via the valves. The supposed goal? Maintain lower temperatures and optimize tire management and overheating.
The FIA is still evaluating
Although the news has inflamed the paddock, The FIA has not yet found definitive evidence to support these accusations. The tyre control system is in fact very rigorous, and any intervention after the tyres have been fitted is impossible for the teams. Pirelli, responsible for supplying and monitoring the tyres, confirmed that it has never observed any anomalies or suspicious attempts in the last races, neither in Mexico nor in Austin. In fact, safety procedures require that Pirelli itself checks and assigns the tyres to the teams, making any unauthorised intervention very difficult.
But Red Bull's accusations do not stop there: in the team of the reigning champion Max Verstappen, it is assumed that some former engineers of the team, now moved to the competition, may have brought with them some secret techniques, perfecting them further. A supposition that lights the fuse even more in view of qualifying and the race.

Water in Tires: Science Fiction or Real Benefit?
The idea of adding water to the tires that McLaren is accused of may seem bizarre, but the principle is technically intriguing. Small amounts of liquid injected into the tires could help dissipate heat during long stints, improving tire life and giving an advantage over rivals forced to cope with higher temperatures. But performing such an operation is complex and risky: the water would have to evaporate before disassembly, otherwise the trick would be easily detectable.
Strategies, controversies and the race for the title
This accusation is part of a long line of suspicions that is characterizing this season. The battle between McLaren and Red Bull is not only played out on the track, but also between strategies and technical ideas that aim for every minimal advantage.The FIA, for its part, is trying to maintain control over an increasingly aggressive Formula 1 even behind the scenes.
As the rain rages on Interlagos, it is clear that this Brazilian weekend will not only be a battle between the best teams in the world championship, but also a test of the integrity of the regulations and the FIA's ability to manage technical tensions. It remains to be seen whether Red Bull's suspicions will be confirmed, or whether Red Bull will have made a mistake... to stay on topic.
