Pirelli has seen no proof of something uncommon in how groups are operating their tyres amid the most recent tech intrigue in F1 over a possible water cooling trick.
Suspicions about a number of groups doubtlessly having discovered a means to assist cool their tyres in races, by injecting water in to them by means of the valves, are understood to have erupted after the Singapore Grand Prix.

It’s understood that this was prompted by indicators of moisture being noticed inside wheel rims after the tyres have been stripped following the grand prix on the Marina Bay circuit.
The FIA has been pushed by Purple Bull to dig into the matter, and its head of single seater issues Nikolas Tombazis is known to have spoken to Pirelli about it in Brazil in addition to have oversight of tyres being stripped after the dash race at Interlagos.
The official scrutineering report from the dash race mentioned that each one tyres that have been inspected after the dash have been compliant with the laws.
Pirelli itself says that, following its chats with the FIA, it’s more than pleased to do something it may well to assist any probe – however says that preliminary evaluation has not pointed to something untoward happening.
Mario Isola, its head of F1 and automobile racing, mentioned: “I can’t see something unusual from the information we’ve. I haven’t got any proof.

“Clearly, as I mentioned, it is as much as the FIA now to determine what to do and to inform us if we will help, as a result of on the finish of the day the one factor we will do is to help them.
“If there may be something we will do to test, or to offer them recommendation on a potential state of affairs, we’re right here to help.
“I am not conscious of any problem, however I heard the story, and I’ve additionally tried to grasp why it must be finished, which now I’ve an concept. However for the remainder, it is all within the palms of the FIA.”
Isola defined that, in concept, it was fairly a easy job to inject water into the tyre – though the physics at play have been fairly sophisticated and it was not with out a draw back when it comes to impacting inside pressures.
“How to do this may be very straightforward,” he mentioned. “You will have a valve – and also you simply put water inside.
“However how the system works is a special story. It is mainly a thermal impact: warmth switch between the tyre and the rim that ought to give extra consistency or much less degradation to the tyre, even in case you have worse management of the strain.
“Clearly, in case you have a vapour steam contained in the tyre you lose the management of the strain as a result of you’ve a strain that’s greater.”
Isola mentioned any crew that did inject water into the tyres to assist with cooling could be going in opposition to an FIA technical directive that was issued just a few years in the past relating to the remedy of tyres.
“The TD got here some years in the past when there was a dialogue on this,” he mentioned. “There was a dialogue additionally on particular gases the place it was advised some groups have been altering the fuel into the tyre to higher management strain.
“Then somebody began to speak about moisture within the tyre, and why we must always have kind of.
“We provide the tyres with dry air inside. We’ve got a dryer related to our system, and so they get all of the tyres with dry air, as within the laws.
“Within the technical directive, it is written that any modification to that is forbidden, and it is fairly clear. However then you must have a transparent proof in case you have a state of affairs like that.”
