Pirelli's second 2017 tyre development test got underway at Mugello on Wednesday with the Red Bull team debuting the wider slick tyres for the first time.
Earlier this week, Ferrari's Sebastian Vettel and Esteban Gutierrez tested the Italian supplier's wet weather tyres at Fiorano, completing more than 280 laps.
Pirelli will conclude its second two-day test with Red Bull on Thursday with test driver Sebastien Buemi as it collects extensive data on the new compounds which are 25 per cent wider than the current Pirelli range.
The front tyres will be 60mm wider (from 245 to 305mm) and the rears will increase 80mm (from 325 to 405mm).
Ferrari will be next to test the slick tyres before Mercedes gets involved in September. All data will be shared with every team on the grid to ensure no one team gains an unfair advantage.
