So a question for the more knowledgeable does the weight of the car include the tyre and wheels they finished on ,and could badly worn tyres lose 1.5kg of rubber as that was the weight George's car was underweight
There was a message to both Mercedes drivers in the early part of the race to lift and coast(save fuel). It was fuel removed for a sample after the race that caused the weight issue, which lead to the car being checked and weighed without the wheels.
I think they knew the car would be underweight at the end, but didn't expect him to finish on the podium or do only the one stop.
Expert opinion there, seeing the car being weighed without the wheels, felt that the tyre wear wouldn't have given the 1.5kg underweight difference. Nor did the fact that there was no lap back to the pit's mean he lost out on the chance to pick up the weight from the track.
