The sudden failure of Lance Stroll (Aston Martin) and Max Verstappen (Red Bull) left rear tires, which caused their crashes during the Azerbaijani F1 GP on June 6, could be related to their "condition. use, "said the manufacturer Pirelli.
The analysis of these tires, but also of those of other single-seaters, "made it possible to establish that there was no production or quality defect on any of the tires, nor any signs of fatigue or delamination", Pirelli announced. in a statement.
"In both cases, the tires show a circumferential rupture on the inner side, a phenomenon that can be traced back to the conditions of use of the tires, despite having respected the prescribed starting parameters (minimum pressures and maximum temperature of the electric blankets)" explains Pirelli.
Pirelli therefore specifies that a "new set of protocols (...) for controlling the operating conditions (of the tires) during a race weekend" has been agreed with the International Automobile Federation (FIA). "We have always respected Pirelli parameters and will continue to follow their recommendations," Red Bull said in a statement.
