Michelin Pilot Sport Cup 2: The Official Tire of the Porsche 911 GT3 RS
Last modified on May 28th, 2026 in News
When Porsche develops one of its most extreme cars, tire choice is never left to chance. For the Porsche 911 GT3 RS, the German manufacturer placed its trust in Michelin and the Pilot Sport Cup 2, tires engineered to push the limits on both open roads and race circuits. Here's what makes this collaboration so remarkable.
Tires Built for Extreme Performance
The Michelin Pilot Sport Cup 2 tires fitted to the GT3 RS aren't just high-performance tires, they were developed specifically to meet the demands of an exceptional vehicle. Compared to the tires on the standard GT3, the dimensions were increased to maximize ground contact surface.
- Front: 265/35 ZR20, increasing the contact patch by 20%.
- Rear: 325/30 ZR21, increasing the contact patch by 18%.
This larger contact area translates directly into improved grip and handling precision, two qualities that are absolutely critical on a car as focused as the GT3 RS.
Bi-Compound Technology: The Innovation That Sets It Apart
To reach this level of performance, Michelin's engineers developed a proprietary technology called Bi-compound. The concept is as straightforward as it is clever: the tread is made up of two distinct rubber compounds, one in the centre and a different one on the edges.
Why the distinction? Because the centre of the tread and its edges serve very different roles:
- The centre carries most of the vehicle's weight in a straight line, providing stability and even wear.
- The edges come into play during cornering and braking, where lateral loads are at their highest.
By optimizing each zone independently, Michelin achieves a more uniform contact pressure across the entire tread face. The result: the Pilot Sport Cup 2 delivers a track tread life 50% longer than its predecessor, the Pilot Sport Cup +. Less wear, more performance, for longer.
A Partnership That Reflects Porsche's Confidence in Michelin
By equipping the GT3 RS with Pilot Sport Cup 2 tires, Porsche isn't just selecting a tire, it's making a clear statement about its confidence in Michelin. And the GT3 RS is far from an isolated case: Porsche has announced its intention to fit several of its most performance-oriented models with Michelin tires, including the 911 GT3, the 918 Spyder, and the Cayman GT4.
This growing relationship between the Stuttgart-based manufacturer and the French tire maker is a perfect example of how the demands of high-level motorsport directly shape the products available to enthusiast drivers.
Michelin Pilot Sport Cup 2: Who Are They For?
While the Pilot Sport Cup 2 was designed with cars like the GT3 RS in mind, it speaks to any driver looking to push their vehicle to the limit on track while retaining full road certification. These are tires for drivers who refuse to compromise on performance.
