Pireli says it may be necessary to revise the construction of their tyres after the failure experienced by Paul di Resta during practice.
Di Resta’s left rear tyre shed its belt of rubber as he drove onto the pit straight during the session. The tyre remained inflated but Di Resta had to bring the car to a stop.
“Obviously there was a problem in the final part of [second practice] that affected the medium tyre on the Force India of Paul di Resta and we?óÔé¼Ôäóre going to investigate the cause of that fully,” said Pirelli motorsport director Paul Hembery.
“Whatever the cause, this is not something we like to see and once we have established all the facts we will decide whether some further modifications to the tyres are required to help avoid this type of issue.”
Pirelli experienced other problems with its tyres during the last race in Bahrain. One of Lewis Hamilton’s tyres failed during practice, causing damage which forced him to take a five-place grid penalty.
Felipe Massa had two tyre failures during the race which Pirelli believe were caused by debris. However they were unsure of the exact cause of Hamilton’s failure.
