Since the Monaco Grand Prix, the FIA has asked teams to log all its running tyre pressure data, which is giving the governing body a good insight into what teams are up to when the cars are out on track.

This comes against the backdrop of suspicions that some outfits have found clever ways to lower tyre pressures after the mandatory readings are taken.

Although there has been talk that a new way of measuring the pressures could be implemented imminently, F1 race director Charlie Whiting has made it clear that the FIA's investigations are still at an early phase.

When asked the possibility of a new way for readings to be taken, Whiting said: "Any such plans or anything similar are in the formative stages. We are some way from changing the current procedures.

"The data logged at the Monaco GP was the start of a research programme, it is ongoing and it's too early to say whether we have any concerns."

Swift response

Although the FIA says that there is no need for an immediate change to the procedures, Pirelli is eager for something to be done soon.

Motorsport director Paul Hembery told Motorsport.com in Canada that he hoped a new way of measuring the pressures - perhaps well before the tyres are fitted to the cars - could be implemented soon.

"We are studying it at the moment," he said. "We have found a few areas that we feel are a little bit grey from our point of view, and we hope to clarify the situation and the procedure over the next week.

"This is a key area for the tyre maker. You need to understand what pressures are being operated in real circumstances, and we need to address it this year.

"This will also stop people investing a lot of money they don't have in trying to find ways to optimise the situation. That is not what we want people spending money on."
