Along with the the new aerodynamic regulation changes, next year’s cars will lower lap times by around three seconds compared to 2016. The full range of wider 2017 tyres (including new tread patterns that will feature on their intermediate and wet compounds) were unveiled on Thusday in the Yas Marina paddock.
Tyres will be around 25 percent wider, with rears up from 325mm to 405, and fronts up from 245 to 305. The diameter will also be slightly biger, but wheel rim size stays at 13 inches. Pirelli’s motorsport director Paul Hembery said “The new cars that will take to the track for the first time in February will have a downforce increase of more than 20 percent”
Pirelli will complete this year’s test programme on their 2017 tyres with a final day of running in Abu Dhabi following this weekend’s Grand Prix.
