Results stand: Lewis Hamilton wins the Italian GP
They resolved the tire pressure measurement that counts is the one that is taken when wheels are fitted to the car in the garage prior to the start.
Some of you may ask why then they would bother taking measurements on the grid right before the start. Presumably this is to make sure pressures are still within specs, not to look cool on TV.
Only a cynic would think Mercedes would show up on the grid with colder tires in order to have a lower effective pressures or that any commercial considerations were part of this decision.
Whatever. Nobody was going to beat Hamilton's W06 today anyway.
