The next stage of Pirelli's 2017 tyre testing got underway on Tuesday, with Ferrari and Mercedes helping to develop its prototype tyres at two different circuits.
Mercedes will be testing the new wider tyres at the Paul Ricard circuit in the south of France over a three-day test, while Ferrari is testing for two days at the Circuit de Catalunya outside Barcelona. The tests are designed to help Pirelli develop its constructions and compounds for 2017 and are conducted "blind" so as not to give an advantage to the teams participating. Data from the test will be analysed by Pirelli and circulated to all 11 teams in the interest of fairness.
