Pirelli have started to test the 2017 specification rubber today, with Ferrari the first team to take to the test track in preparation for the revised aerodynamic rules for next season.
The new tyres which are 25% wider than the current version, were fitted to a 2015 spec Ferrari in the hands of race driver Sebastian Vettel. The most notable change to the car was a larger rear wing to simulate the higher downforce expected near season.
Although the dry weather tyre was used just for a couple of laps, the majority of the testing day was for the wet and intermediate tyres. Taking place at the Ferrari test track at Fiorano it has its own artificial sprinkling system, to give the conditions needed for the wet and intermediate.
Haas driver Esteban Gutierrez will take over duties tomorrow, with Red Bull next in line to run the new rubber.
