Pirelli tyres exploding unacceptable says Perez 10 October, 2013 Sergio Perez returns to the pits after a blowout during the British GP McLaren driver Sergio Perez has stepped up his attack on Formula 1 tyre supplier Pirelli, after his tyre exploded during the Korean Grand Prix. Pirelli had played down the Mexican’s failure, saying it was simply caused by Perez badly locking the brakes on his MP4-28. “That something happens after a brake lockup is absolutely unacceptable,” Perez is quoted by Auto Motor und Sport. He was also a victim of a tyre explosion during the British Grand Prix in June He said he doubts Pirelli’s official explanation, “I’ve never heard of a brake [lockup] automatically leading to an explosion of tyres. For me it was not normal; it’s unacceptable that the tyre explodes.” Perez’s attack follows those of Fernando Alonso and Mark Webber, towards the end of a tumultuous season for Formula 1’s official tyre supplier. “I knew that there were cars behind me and I just prayed that the rubber pieces do not hit them,” Perez continued. He revealed: “We could see that the tyre temperatures were going up, which is why I braked five metres earlier and with less pressure on the pedal. “I was surprised when the brakes locked. I came around the corner and the tyre exploded on the straight,” added Perez.
