Pirelli say 'mode' of recent tyre failures need looking into after Di Resta incident

Pirelli chief Paul Hembery says the Italian manufacturer's disquiet over the recent examples of tyre failures centres on the way the tread is giving way, rather than over any potential increase in problems.

Speaking in the earlier team bosses' press conference at Barcelona, Force India's Technical Director Andrew Green admitted the failure which cut short his driver's afternoon long run had been "completely unexpected". Hembery says Pirelli's technicians need to conduct a more detail examination of the damaged tyre but that it was clear that it overheated. "It's always very difficult because you get a back of bits back. But it's certainly caused by overheating of the tread," he added.
