Pirelli unsure why Vettel punctured

Pirelli is still unsure what caused the puncture that put Sebastian Vettel out of the Abu Dhabi Grand Prix on the opening lap. The Red Bull driver started well from pole position and led into Turn 1, but ran wide onto the kerb exiting the corner; his right-rear tyre deflating instantly and causing him to spin off the track as he moved left for Turn 2
