Pirelli: Perez tire failure nothing to be concerned about

9 Comments

Pirelli motorsport director Paul Hembery has said that Sergio Perez’s tire failure during the Korean Grand Prix was not caused by an underlying problem with the tires themselves, but instead a result of a flat spot caused by a lock-up.

The Korean International Circuit has traditionally been tough on tires, and many drivers made mistakes during practice as they looked to find the limit when it came to pushing on the Pirellis. However, on lap thirty-one, Perez locked up heading into turn one (pictured), producing a huge amount of tire smoke. Seconds later, his front-right tire delaminated heading along the straight between turns two and three, warranting a safety car to clear the debris that gave Mark Webber a puncture.

“Regarding Sergio Perez’s front-right tyre issue we have been able to determine very quickly that it was the result of a flat spot caused by a lock-up under heavy braking,” Hembery said. “We’re obviously on exactly the same construction as we raced here last year, so there’s no underlying problem, while flat spots or punctures have just always been an integral part of racing.”

Pirelli’s tires have come under extra scrutiny this season following a series of failures at the British Grand Prix back in June that prompted the Italian supplier to re-introduce last year’s constructions in Hungary before the summer break. However, this incident is merely a combination of factors, meaning that there are no concerns that the same issues may flare up again in the final five races.

It was confirmed last week that Pirelli would continue to supply Formula One with tires in 2014 despite a turbulent season.

Ganassi, which placed all four of its drivers in the top 10 at Detroit, has three of the top four in the championship standings with Scott Dixon ranked fourth after a fourth at Detroit.
