Formula One tyre supplier Pirelli warn they could quit F1 Monaco: Formula One tyre supplier Pirelli warned teams on Thursday that they will quit the sport at the end of the season if a new contract from 2014 is not agreed soon. Motorsport director Paul Hembery did not hide his impatience when he told reporters at the Monaco Grand Prix that time was running out for the Italian company to design and test tyres suitable for radically different 2014 regulations.

"Apparently on September 1 we are meant to tell them (the teams) everything that they need to know for the tyres for next season. We are now mid-May so you can imagine how ludicrous that is when we haven't even got contracts in place," he said. "So maybe we won't be here anyway..."

Asked how much of a maybe that was, and how seriously Pirelli were considering walking away, the Briton added: "At a certain point somebody has got to make a decision. "Things are getting, as far as we can see, extremely serious because the changes next year are so substantial that the sport has to make a rapid decision."

Formula One is switching to a new 1.6 litre V6 turbocharged engine with energy recovery systems next season and the tyres will also have to change to cope with the new unit's characteristics. Hembery said the indications were that the power delivery and top speed would be very different, the aerodynamic loads would change and even the size of the tyres was to be decided....
