2015 Italian GP: Merc cleared, Hamilton's win stands

MONZA, Italy - Mercedes team boss Toto Wolff admitted to relief on Sunday (September 6) evening after a long and crucial meeting with the stewards.

Lewis Hamilton's Monza victory was in doubt because Pirelli, supported by the FIA, found on the grid that his tyre was 0.3 PSI under the new mandatory limit.

EXPECTED HAMILTON TO BE DISQUALIFIED

Apparently a clear technical breach, with both performance and safety implications, many in the paddock had expected the British driver to be disqualified.

But after a long wait, the FIA finally announced that Hamilton can keep his win.

A statement read: "The stewards have determined that the pressure in the tyres concerned were at the minimum start pressure recommended by Pirelli when they were fitted to the car," a statement read.

It added that Mercedes had set the pressures "supervised by the tyre manufacturer", and therefore recommended that the protocols for ensuring actual race-start pressure are improved for the future.

The statement went on to say: "The stewards recommend that the tyre manufacturer and the FIA hold further meetings to provide clear guidance to the teams on measurement protocols."

Mercedes confirmed the news via their official Twitter feed:

CONFIRMED: FIA stewards conclude no further action required for @LewisHamilton. The result stands: @LewisHamilton is your #ItalianGP winner!
