Having heard from the Technical Delegate, the Team Representatives, and the Pirelli Team Tire engineer, the Stewards have determined that the pressure in the tires concerned were at the minimum start pressure recommended by Pirelli when they were fitted to the car. In making this determination regarding the pressures, the Stewards noticed that the tire warming blankets had been disconnected from their power source, as is normal procedure, and the tires were significantly below the maximum permitted tire 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 Tire Manufacturer, for the safe operation of the tires.

There, the Stewards decide to take no further action.

Nevertheless, the Stewards recommend that the Trey Manufacturer and the FIA hold further meetings to provide clear guidance to the teams on measurement protocols.
