Pirelli develops tyre for new Pagani hypercar

Pagani has a new hypercar, the Huayra Roadster BC, and once again Pirelli has been tasked with supplying the tyres for it.

The P Zero Trofeo R tyres will be OE for the Huayra Roadster BC and will be available in size 265/30 R20 at the front and size 355/25 R21 at the rear.

For the first time, the two Italian firms got tyre development underway by using modelling and predictive simulation; a virtual pre-development process that allows a computer model to accurately replicate the dynamic characteristics of the car without the need to actually make real tyres for it.

This means reduced lead times, greater harmony between objective data and subjective impressions behind the wheel, as well as an end product that is even more closely matched to the car that it is intended for. This is the same simulation techniques used to develop P Zero tyres for Formula 1.

The joint development process between engineers from Pirelli and Pagani began by establishing a new size for the front tyre, with wider channels, a bigger cord, and larger rims. This offers an increased contact patch, which has the added benefit of greater strength to support the extra aerodynamic downforce loads. The driving dynamics have also been improved, thanks to less sliding from a stiffer tyre structure. The Roadster BC consequently benefits from a sharper turn-in, with a more linear driving experience and less tendency towards understeer.

Another advantage of the increased tyre size is better braking: the latest Pagani now manages to pull 2.2g under braking. The work on the new P Zero Trofeo R front also meant that the rear tyre had to be revised, to maintain the right balance between the two axles. Pirelli’s engineers modified the tread pattern design – laying it out differently and increasing the size of the blocks as well as the longitudinal grooves – which has resulted in better traction under acceleration: a like-for-like improvement of seven per cent.

Marco Tronchetti Provera, Pirelli’s Chief Executive Officer and Vice Chairman said: “Every time we work together [with Pagani], we find ourselves facing exciting new limits to overcome. This is an amazing inspiration, which allows us to carry out research and development with an extraordinary partner. Pirelli has innovation and the constant desire to improve at the very heart of its DNA, which is why we consistently look for technological excellence in each product. Every project with Pagani always brings us something new.”
