Is the BMW M2 equipped with run-flat tires?

The BMW M2 does not come with run-flat tires. Here is the relevant information: 1. The original tires on the BMW M2 are Michelin PSS (Pilot Super Sport), a product specifically designed for top-tier ultra-high-performance sports cars. The front tire size for the M2 is 245/35R19, and the rear tire size is 265/35R19. 2. The Michelin PSS tires are ultra-high-performance tires with exceptional sports performance, as evidenced by their continuous ribs, large tread blocks, wide drainage grooves, and flat tread surface. Through optimized tread pattern design, the Michelin PSS maintains a nearly constant contact area with the road, whether in straight-line driving or cornering, resulting in more stable tire grip.
I've been driving a BMW M2 for three years, and it came with run-flat tires from the factory. The name 'run-flat tire' is more accurate, as the sidewalls are particularly thick, allowing you to continue driving for about 80-100 kilometers even if the tire is punctured. This design is quite user-friendly. Once, I ran over a nail on the highway, the tire pressure warning light came on, and I managed to drive to the service area before dealing with it. However, the downside of run-flat tires is their poor comfort—they are especially bumpy over speed bumps, and the road noise is significantly louder compared to regular tires. BMW equipped the M2 with these tires mainly to account for its rear-wheel-drive characteristics, ensuring better handling stability in case of a tire blowout. When replacing the tires, be careful not to opt for cheaper regular tires unless you're willing to carry a spare tire in the car.
As a frequent track enthusiast, my M2 came with run-flat tires as standard equipment. These run-flat tires have sidewalls that are 50% stronger than regular tires, maintaining vehicle stability even during a blowout. This is particularly crucial for high-powered rear-wheel-drive cars like the M2, significantly reducing the risk of losing control. However, the drawbacks are obvious: they weigh 15% more than regular tires, affecting acceleration performance; their wet-weather grip is mediocre; and they cost about 30% more. I later switched to semi-slick tires for track use but reverted to run-flats for daily driving. Be cautious not to purchase counterfeit products—BMW-certified run-flat tires feature the RSC marking on the sidewall.
