FIA open to new F1 tyre safety guidelines for Monza

The FIA is prepared to step in and impose whatever tyre guidelines Pirelli requests for the Italian Grand Prix, to ensure there is no risk of trouble at Monza.

Investigations are ongoing between Ferrari and Pirelli to get to the bottom of why Sebastian Vettel's tyre failed so spectacularly on the penultimate lap of the race.

The FIA is in dialogue with both team and tyre manufacturer to help find an answer and make sure lessons are taken on board about what happened.

And with leading F1 drivers having called for action as they deem the failures 'unacceptable', motor racing's governing body has said it will step in and impose any operating limits that are viewed as necessary.

An FIA spokesman said: "We are working closely with Pirelli and Ferrari to make sure that what can be learned is learned, and what needs to be changed is changed.

"If any further guidelines are suggested, we will enforce them."

Mileage limit possible

The FIA already monitors cambers, both when stationary and at high-speed, plus starting pressures.

And, as revealed by Motorsport.com, more rigorous enforcement of tyre blanket temperature limits was imposed at Spa amid suspicion that some teams were heating tyres too much.

With Pirelli suspecting that Vettel's failure was related more to the stint length than anything else, it is possible the company could request a mileage limit on safety grounds. The matter may be discussed with teams imminently.

It was such a concept that, in a statement on Sunday night, it suggested had been ignored back in 2013.

Pirelli motorsport director Paul Hembery said in Belgium: "We discussed that a few years ago when we were a little bit more aggressive and people were pushing to try to reduce the number of stops.

"But it is hard to enforce and you take away the engineering aspect of the car where someone might be able to engineer a car to a point where they can reduce the number of pit stops.

"At that time, it wasn't feasible to introduce it. But maybe we can go back to having those advice levels and say 'no more than x laps on a certain tyre'."

Standing wave theory

Ferrari and Pirelli have yet to issue a formal statement outlining exactly what happened with Vettel's tyre.

Pirelli has so far only suggested the wear issue, but several sources have claimed that there is no evidence of excessive wear on any of the other three tyres after the race.

However, it is understood that a thorough examination of other teams' tyres by Pirelli is also underway to discover evidence of wear elsewhere.

Debris has also been put forward as a possible explanation, but the lack of a loss of pressure in Vettel's tyre shortly before the failure suggests that may not have been the case on this occasion.

One theory now being evaluated is that it could have been a combination of factors caused by the unique forces cars experience at Spa, with high-speed corners, the compression of Eau Rouge and long straights.

The failures may even have been caused by the appearance of standing wave in the tyres, which perhaps contributed to the issues. Photographs of cars through Eau Rouge over the weekend showed the high forces being put through the rubber.

The challenges of Monza are different. For although there are high speeds, the cornering forces are much less.
