Perez puncture caused by cut on tyre – Pirelli

2013 British Grand PrixPosted on Author Keith Collantine

Sergio Perez, McLaren, Silverstone, 2013Pirelli say Sergio Perez’s puncture during third practice was caused by a cut on the tyre.

Perez suffered a left-rear puncture during the final hour of practice which damaged the floor at the rear of his McLaren.

“During the final free practice session this morning we saw a deflation on the rear left tyre of Sergio Perez,” said motorsport director Paul Hembery.

“First findings show that this was unequivocally caused by a cut in the inner sidewall: something went into the tyre, pierced it, and then came out again, in the direction of travel.

“Whether that was a piece of debris or the edge of a kerb is hard to say at the moment and it is important to point out that this incident was unrelated to any of the delamination issues we have had in the past.”

Several drivers experienced tyre failures earlier in the year which led Pirelli to revise the construction and preparation of their tyres. However not all of Pirelli’s proposed changes have been introduced as they have been unable to obtain the necessary support from all the teams.
