Lewis Hamilton keeps Italian Grand Prix victory after FIA reach deflate-gate verdict

Lewis Hamilton and Mercedes cleared over tyre pressure levels.

FIA race stewards have reached a decision that sees no further action warranted and Lewis Hamilton keeps his Italian Grand Prix victory after an investigation into their tyre pressures.

As the end of the 2015 Italian Grand Prix approached its climax, Hamilton and his Mercedes team-mate, Rosberg, were investigated by the FIA regarded the pressures of their rear-left Pirelli tyres.

During the race, Hamilton had dominated and took a commanding victory by 25-seconds to Sebastian Vettel. However Lewis had been asked to push at the end in case of a penalty with the team fearing a bad outcome of a possible investigation.

Luckily for Hamilton and Mercedes, after a meeting with Pirelli and Mercedes representatives after the race, the FIA stewards decided Mercedes had not done anything wrong. Leaving Hamilton with the win.

The stewards reached their decision based on evidence from Mercedes that showed the tyres were at the correct pressures when fitted but other circumstances resulted in a drop of pressure before the race began.

“Stewards have determined that the pressures in the tyres concerned were at the minimum start pressure recommended by Pirelli when they were fitted to the car,” said the stewards in their decision.

“The stewards noted that the tyre warming blankets had been disconnected from their power source, as is normal procedures, and the tyres were significantly below the maximum permitted tyre blanket temperature at the time of the FIA’s measurement on the grid, and at significantly different temperatures from other cars measured on the grid.

“Further, the Stewards are satisfied that the team followed the currently specified procedure, supervised by the tyre manufacturer (Pirelli), for the safe operation of the tyres.

“Therefore the stewards decide to take no further action.

“Nevertheless, the stewards recommend the tyre manufacturer and the FIA hold further meetings to provide clear guidance to the teams on measurements.”
