How is this even possible??????

Translation:

In Brazil, Red Bull was once again in the role of the accuser. This time it was about filling the tires with water. The trick is supposed to help cool the tires better from the inside over long distances. The water is supposed to be injected through the valves. Apparently even small amounts achieve the desired effect. Several teams are said to be benefiting from this practice in the long run, including McLaren.

The FIA ​​is already investigating the allegations. There were no suspicious observations at the last two races in Austin and Mexico City. Pirelli would have to report the slightest irregularities to the FIA's technical stewards. According to the Italian tire manufacturer, however, there has not been a single suspicious occurrence this year.

Neither Pirelli nor the FIA ​​want to comment officially on the case. However, behind closed doors it is said that the story is considered to be just another storm in a teacup.

How does water get into the tires?

When using the trick, the first question must be how the water is supposed to get into the tires without Pirelli noticing. And how the water is supposed to disappear after the race other than through evaporation. Tires and rims are coded. The FIA ​​randomly assigns the tires to the rims registered by the teams. The tires are mounted and dismounted by Pirelli's service technicians.

Once the tires have been fitted, no team is allowed to tamper with them. The teams themselves do not have the tools to remove tires from the rim and put them back on. Tires cannot be reused once they have been removed. The only way to add water is through the valve. But injecting fluids unnoticed would be extremely difficult given the number of guards and Pirelli engineers in the garages.

Such a trick would also be extremely risky. If the water does not evaporate in the three to four hours after the race before the tires are removed, you will quickly come under suspicion. Apparently, Red Bull itself experimented with water in the tires many years ago. At the time, the trick was not explicitly forbidden. But the FIA ​​promptly closed this loophole. In the defending champion's camp, it is now assumed that former Red Bull employees have pulled out the trick again and refined it with their new teams.
