Pirelli`s 18-inch F1 tyre
Pirelli is introducing a new 18-inch tyre design concept to showcase the way that Formula One could look in the near future. But rather than an abstract design, this is a fully functional tyre, capable of completing demonstration runs around Silverstone during the in-season test session.
The 18-inch tyre is an idea that Pirelli has promoted ever since the company was first announced as Formula One official tyre supplier back in 2010. Larger wheel and tyre sizes reflect modern market trends, with the adoption of a larger size invariably leading to even greater technology transfer between Formula One tyres and road car tyres. Pirelli would only progress this initiative if there were a genuine desire from the teams, promoter and other stakeholders to move in such a direction. This is in accordance with the Italian firm’s consistent philosophy of being a technical partner and sponsor entirely at the service of the teams and the sport, in order to benefit the spectacle as a whole.
However, the technology is in place already to produce this type of tyre with the same standards of performance and reliability set by the current 13-inch rubber. Indeed, with a new tyre concept right at the beginning of its development curve, the possibilities are almost limitless. These include even larger sizes in future.
A new 18-inch tyre would not be without its technical challenges to produce, although the pay-off would be increased rigidity through having less flexibility in the sidewalls. Nonetheless, this necessary movement forms an important part of the current Formula One car’s suspension and damping. A smaller sidewall would also inevitably lead to drastically reduced branding space. In spite of this, Pirelli is completely ready and capable to move ahead with development of such a tyre should the teams wish for it to happen.
Tyres that will be circulating around Silverstone on wednesday, 9 July. Lotus is scheduled to take a 2014 E22 out on the Silverstone Grand Prix track equipped with one-off Pirelli P Zero 18-inch concept tyres.
