Already Porsche's best performance car, the 911 GT3 is about to get even better thanks to two new custom-made Pirelli tires. The Italian tire maker—already responsible for equipping the entire 911 lineup with its P Zero range—has developed two versions specifically for Porsche’s most hardcore model: the P Zero R and the P Zero Trofeo RS.
The 911 GT3 RS already comes standard with Pirelli’s Trofeo RS tires, a benchmark for track-day enthusiasts. But the new P Zero R is aimed at GT3 owners who plan on using their cars on the road as well. Its bespoke compound provides strong grip across a variety of surfaces, with a special focus on wet performance—often a weak spot for high-performance tires such as this.
Pirelli designed the P Zero R to perform consistently across different temperatures and climates, even when the tire hasn’t reached its ideal operating window. Two distinct compound structures for the front and rear tires help further sharpen the GT3’s dynamics: the front tires prioritize sensitivity and precision, while the rear tires deliver the strength and stability needed to handle the boxer engine’s high loads and the GT3’s dynamic chassis.
For drivers who spend most of their time on the track, Pirelli also offers the P Zero Trofeo RS, the most extreme street-legal tire in its lineup. It’s engineered for long, demanding sessions, maintaining predictable grip and directional stability lap after lap.
Experience gained from working on the 911 GT3 RS allowed Pirelli engineers to transfer their know-how directly to the GT3’s new tailor-made tires, resulting in a more durable semi-slick that stays stable during rapid load changes.
Although designed with the 911 GT3 in mind, the Trofeo RS also performs exceptionally well on other Porsche models—such as the Taycan Turbo GT—which showcases its versatility, even for high-performance electric vehicles.
Both GT3-specific tires are part of Pirelli’s Perfect Fit program, which focuses on creating tailor-made tires for each vehicle model. They feature the "N" marking, indicating joint development with Porsche and a dedicated design for the GT3.
By using advanced simulation tools developed with research centers at the University of Milano-Bicocca and in Breuberg, Pirelli has cut development time for these new fitments by up to 30 percent. The company has also reduced the number of physical prototypes needed, making it easier and faster to produce ultra-high-performance tires like these.
