Pirelli to test a new 18-inch tire concept at Silverstone

Pirelli is introducing a new 18-inch tire 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 tire, capable of completing demonstration runs around Silverstone during the forthcoming in-season test from next Tuesday to next Wednesday (8-9 July).

The 18-inch tire is an idea that Pirelli has promoted ever since the company was first announced as Formula One official tire supplier back in 2010.  Larger wheel and tire sizes reflect modern market trends; with the adoption of a larger size invariably leading to even greater technology transfer between Formula One tires and road car tires. 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.

These tires, developed and created by Pirelli’s engineers as part of the company’s premium strategy, serve only as an example of what is possible. However, the technology is in place already to produce this type of tire with the same standards of performance and reliability set by the current 13-inch rubber. Indeed, with a new tire 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 tire 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 tire should the teams wish for it to happen. And proof of this proactive capability lies in the existence of the tires that will be circulating around Silverstone next week.

Lotus is scheduled to take a 2014 E22 out on the Silverstone Grand Prix track during next week’s test on Wednesday, equipped with one-off Pirelli P Zero 18-inch concept tires.

Pirelli’s motorsport director Paul Hembery commented: “The 13-inch tire is no longer relevant to the everyday road user, because even an 18-inch tire is used by standard vehicles these days. While 18-inch tires would be a big step for Formula One, there are many other motorsport series that already use this size. So there’s scope to go even bigger than that in Formula One in years to come. In order to underline F1’s role as a test bed for future mobility solutions, we believe that it benefits everybody to have as close a link between road car tires and competition tires as possible: a belief we have held ever since we introduced the low profile tire from competition to road use back in the 1970s.

However, we’d like to emphasize that this move is not something that we are actively pushing for, as our role in Formula One is not to instigate changes. Instead, it’s to help teams and drivers make the most out of the equipment, regulations and resources they have at their disposal – whatever they decide that framework is going to be.”

The decision to demonstrate this ground-breaking prototype at Silverstone has been taken at the very top of the company, in order to showcase Pirelli’s reactivity and technical know-how.

Pirelli’s head of research and development, Maurizio Boiocchi, concluded: “Our competition career started with tires that had a direct relevance to the road when Prince Borghese drove his Itala to victory on the 1907 Peking to Paris race. More than 100 years later, this is a concept that we are ready to adopt again. The tire you will see next week is principally designed to demonstrate aesthetics rather than performance. But the speed of our reaction means that we could have a production-ready example within months if required.  In the meantime, we look forward to hearing everybody’s views about our latest concept, and we hope that people enjoy seeing something out on track that is a little different.”
