Innovation and technology. Two key words for Pirelli, always looking to the trends of an evolving automotive market. This is how the P Zero E was born, the new tyre that integrates the most recent technical innovations developed by Pirelli to serve the latest trends in electrified and sustainable mobility. The new tyre is characterized by several elements, let's find out.
THE FIRST UHP TYRE WITH MORE THAN 55% OF SUSTAINABLE MATERIALS*
Thanks to years of research on new materials and a careful selection of suppliers, Pirelli is first to produce a high-performance tyre with 55% of its materials of natural and recycled origin throughout the launch range*, as certified by Bureau Veritas: a world leader in verifying conformity and certification in quality, environment, health, safety, and social responsibility (to ISO14021 standard). What is the main challenge for Pirelli's R&D? Matching sustainability with the high performance needed from a UHP tyre.
The road that the engineers have gone down will lead to other products in future that contain a high percentage of natural and recycled materials, which will be identified by a dedicated and bespoke sidewall logo, starting from the P Zero E. Pirelli's study of the entire lifecycle of the P Zero E, which has also been verified by Bureau Veritas, shows a 24% reduction in CO2 emissions compared to a previous generation Pirelli tyre**. Furthermore, the attention paid to the materials used has allowed a reduction in the amount of fossil and mineral-derived ingredients, which have instead been swapped for primary materials that are natural and recycled in origin (-12 kilograms compared to an equivalent P Zero in the same size***).
THE ONLY UHP TYRE WITH A TRIPLE A RATING ACROSS THE ENTIRE RANGE
Pirelli P Zero E has obtained the highest rating (A) in all parameters of the European tyre label in all available sizes. This starts with rolling resistance, because of the specific compounds used (Rolling Reduction Compounds), which help to increase the range of battery-powered vehicles and extend tyre life thanks to reduced wear. The compounds also play a fundamental role in enhancing car control throughout various different driving situations, particularly wet braking. Another key area of development to obtain the triple A classification was the tread pattern, designed using virtualisation and simulation techniques derived from motorsport.
PIRELLI ELECT TECHNOLOGIES THROUGHOUT THE RANGE
The entire P Zero E range is distinguished by the Elect marking on the sidewall, which identifies the package of technologies developed by Pirelli to enhance the characteristics of electrified cars. Pirelli Elect technology is designed to enhance the performance of these vehicles, without compromising durability of the tyre. When choosing tyres for electric vehicles, there are also two other factors to consider: noise (both inside and outside the passenger compartment) and battery range.
PIRELLI'S NEW RUNFORWARD TECHNOLOGY
Pirelli's new RunForward technology, which makes its debut in the P Zero E, is designed to maintain control of the car in the event of a puncture and allow journeys to continue. This system consists of reinforcing panels on the internal and external sidewalls of the tyre that support the structure and allow maximum speeds of 80kph for up to 40 kilometres, even with zero pressure****. The structure and compounds of tyres equipped with Pirelli RunForward technology consequently deliver driving and acoustic comfort comparable to a traditional tyre, while still keeping rolling resistance low. This technology was designed in particular for battery electric vehicles, which require quiet tyres and often don't come with a spare wheel due to the presence of the batteries. Another advantage of Pirelli RunForward tyres is that there is no need to have special rims to benefit from all the advantages of this technology.
* Thanks to a combination of physical segregation and mass balance approach. Depending on tyre size, bio-based and recycled content ranges between 29-31% and 25-27% respectively. Bio-based materials are natural rubber, textile reinforcements, bio-chemicals, bio-resins and lignin, while recycled materials are metallic reinforcements, chemicals and - through mass balance - synthetic rubber, silica and carbon black.

**** Pirelli internal tests. Tyres equipped with RunForward technology have successfully reached 40 kilometres with zero pressure. The tests were carried out on the most heavily used wheel in the following circumstances:
- Sizes: 235/40R19 96Y XL, 235/45R18 98W XL, 255/45R19 104Y XL
- Weight on tyre: up to 627kg
- Vehicle weight up to: 2.186kg
