Formula One’s official tire supplier Pirelli remains uncertain as to the cause of Lewis Hamilton’s puncture during final practice for the Bahrain Grand Prix.

The blowout had a damaging effect on Hamilton’s car and his race weekend. The failure wrecked his suspension and gearbox – the latter had to be replaced which forced Hamilton to take a five-place grid penalty.

Pirelli motorsport director Paul Hembery told Autosport: “We will take all the pieces apart and do a full lab analysis. That will either confirm our initial findings, or make us realize that we need to do something and have to implement some changes.”

“There will be a full analysis. We treat every incident very seriously.”

Giedo van der Garde, who was running behind Hamilton at the time, also suffered a puncture which was caused by a piece of metal. Pirelli originally believed this also caused Hamilton’s tire to fail, but not admit they are “not really sure about how it happened”.

Having initially examined the tire at the circuit, Pirelli has taken it to their headquarters in Milan for further examination.

Pirelli remain convinced that both of Felipe Massa’s punctures during the race were caused by debris.
