It may only be the first day of the Formula 1 annual summer break, but Ferrari’s Sebastian Vettel is already back on track testing Pirelli’s new wider tyres for the 2017 racing season.

Pirelli has been asked to develop tyres which are bigger and wider, thus delivering more grip, making the tyres more durable for 2017, as part of a re-construction of the technical regulations.

There have already been tests conducted by the sport’s tyre supplier about the compounds, however the current week will see tests running with the wider tyres by Ferrari at Fiorano and Red Bull at Mugello.

Earlier today, Pirelli released the first photos of Vettel on-track whilst testing the wider tyres and some new bodywork, including a new rear-wing on his car.

All tests conducted are on modified versions of the 2015 cars, known as ‘mule’ cars.

Following Vettel’s testing today [Monday], Haas’ Esteban Gutierrez will test at Fiorano on Tuesday, with Red Bull then taking over at Mugello on Wednesday and Thursday as Sebastien Buemi will participate in his first Formula 1 test in two years.
