The Brazilian Grand Prix stirred up Formula 1’s latest technical storm, as the FIA responded to swirling rumors of teams potentially using water cooling in tyres to gain an advantage. Amidst the heightened speculation, FIA President Mohammed Ben Sulayem addressed the accusations, stating, “We take these claims seriously and are actively ensuring that the regulations are clear and adhered to by all teams. No room exists for ambiguities where the integrity of the sport is at stake.”
The controversy began with suspicions that certain teams, particularly Red Bull’s rival McLaren, may have attempted to keep tyres cooler by adding small quantities of liquid during inflation. Such a tactic could maintain tyre performance and lifespan by controlling temperature fluctuations, providing an edge in both speed and endurance on the track. Red Bull, who previously utilized a similar method before it was banned, expressed concern that others may be exploring this grey area, allegedly spotting watermarks inside rims during recent tyre inspections at Pirelli’s base.
However, the FIA inspection at Brazil GP revealed no trace of extra moisture in the tyres. Yet, with teams under close scrutiny, speculation remains on whether any subtle manipulations occurred earlier this season. The technical rules specify that tyres must be inflated solely with dry air or nitrogen, without adding moisture or other elements, a standard Pirelli upholds.
Ben Sulayem emphasized that while inspections have upheld compliance, the FIA’s vigilance will continue to prevent any “backdoor tactics” that might compromise fair play. This response underscores Formula 1’s focus on rigorous enforcement of technical regulations and balancing innovation with transparency on the track.
