As part of an effort to make F1 cars smaller and lighter, Pirelli agreed to reduce the front tyre width by 25mm and the rear tyre width by 30mm. The tyres themselves will also become smaller in diameter, going from the current 720mm diameter to 705-710mm, although F1 will still be using 18-inch wheels.
Despite the reduced tyre sizes the FIA is not projecting Pirelli's new tyres to be significantly down on grip compared to their current product.
