Testing of Pirelli’s wider 2017 Formula 1 tyres continued at the Circuit de Barcelona-Catalunya in Spain on Wednesday.
Nico Rosberg was at the wheel of a modified 2015 Mercedes in Spain, but cooler temperatures and a rain shower in the afternoon limited his running.
The current F1 championship leader still managed 60 laps, completing 46 on dry weather tyres in the morning and 14 on the wet 2017 tyres.
Pirelli’s tyres will increase in width by 60mm at the front (245 to 305mm) and 80mm at the rear (325 to 405mm) for next season.
Mercedes, Ferrari and Red Bull have already completed tests with Pirelli in preparation for 2017. The current Mercedes test at Barcelona will conclude on Thursday.
Meanwhile Red Bull will complete a two-day dry tyre test at the Yas Marina Circuit in Abu Dhabi from the 14-16 October.
