Pirelli ‘out-thought’ by teams running lower than expected F1 tyre pressures

Red Bull’s Max Verstappen and Aston Martin driver Lance Stroll both suffered high-speed es along Baku’s main straight when their tyres suddenly failed during the race.A Pirelli investigation concluded that the blow-outs were “related to the running conditions of the tyre” and were not induced by debris, despite both Red Bull and Aston Martin insisting they had adhered to the parameters set out by F1’s official tyre supplier.Speaking ahead of the French Grand Prix at Paul Ricard on Thursday, Isola revealed teams had indeed reduced their tyre pressures but stressed they were still in compliance with the regulations and the starting minimum tyre pressures.Asked if Pirelli had been out-thought by the teams, he replied: “Probably, yes.”If they were running in a condition that was not expected by us it means that obviously, they found a way to run in a condition that was expected.Related ArticlesaccImages.createImage(); Hamilton and Bottas to swap F1 chassis for French GPaccImages.createImage(); Leclerc expects Ferrari to be “back to reality” in F1’s French GP”How did they achieve that?

If the same happens next year when, with a standard sensor, we impose a running pressure, in that case, they will be against the regulations.”But this is not the case this year, and it is not possible to do that simply because we don’t have a sensor that we can rely on measurement.”That’s why each team is looking for performance. They are here racing, not to cruise on track. In looking for performance, if you go with a bit lower pressure you get some performance.””5Earlier in the day, F1 championship rivals Lewis Hamilton and Verstappen had disagreed over the outcome of the investigation, with Hamilton saying Pirelli were not to blame.The FIA has introduced new protocols for this weekend’s French GP that will see more stringent checks on both tyre pressure and temperature imposed.
