Lewis Hamilton has admitted he only did about 30 laps of driving in Mercedes’ simulator over the winter. The 36-year-old said the main reason for that is because Pirelli’s tyres have changed significantly for the new season. “You can get an idea from the tyre models, but until we’ve actually driven it in Bahrain we won’t know if it’s right,” said Hamilton. “Only then can we pass on information about the behaviour of the tyres to the team, which can then be put into the simulator through an update. “At the moment we have no more than an estimate of how the tyres will work.”.
