Hamilton's masterly win in Italian GP under tyre scrutiny

Monza

LEWIS Hamilton extended his lead, at least provisionally, in this year's drivers' world championship to 53 points on Sunday when he drove to a flawless and consummate victory in a typically dramatic Italian Grand Prix.

As nearest rival and Mercedes team-mate Nico Rosberg retired with a blown engine with two laps to go, Hamilton took full advantage on a day when his perfect drive ended amid chaotic scenes and reports that his car had raced with illegal tyre pressures.
