F1: Palmer tire failure 'case closed'

Pirelli believes the tire blowout suffered by Jolyon Palmer in Friday practice in Spain was an isolated incident and now considers the case closed.

Palmer’s left-rear, which had just begun its fifth lap of use, blew as he headed down the long main straight. It followed a problem for Esteban Ocon in the same car that morning, but that puncture was put down to debris being picked up by the right-rear tire.

On Friday, Pirelli was perplexed by the incident after it revealed there was no sign of a puncture either in the outer wall or tread, no sign of the rim cutting into the tire and no suspension issue. The inner wall totally disappeared and there are numerous pieces missing given the level to which the tire was destroyed.

Pirelli says further investigations on the bits that were recovered continued late into Friday night and included checking all the video evidence but the results showed nothing untoward.

After exploring all possible avenues and given there was just one failure rather than a number of teams suffering problems, Pirelli feels confident there is not a structural issue and considers the case closed.
