Are Tesla Tires Run-Flat?

Tesla tires are not run-flat. Here is the relevant information: 1. Run-flat tires: The technical name for run-flat tires is "Self-Supporting Run-flat Tires," abbreviated as RSC. The sidewall of an inflated tire is the main part that supports the vehicle's weight, especially for tires with a larger aspect ratio (the ratio of tire height to width). The sidewall is very "thick," and severe "tire blowouts" usually cause the sidewall to rupture instantly, causing the tire to lose support immediately. This results in an abrupt change in the vehicle's center of gravity, particularly for front-wheel-drive vehicles where a front tire blowout can lead to an immediate shift in the center of gravity, potentially causing the vehicle to lose control. 2. Composition: The run-flat tire consists of an outer tire, a standard inner tube, a spare inner tube, a steel rim, a gas generator (or gas storage chamber), a pressure sensor, and a control unit.
I found that not all Tesla's factory-fitted tires are run-flat tires. When I accompanied a friend to pick up his Model Y, I specifically checked and saw that it came with regular Michelin quiet tires. However, Tesla does offer run-flat tires as an option. I've seen a Model S owner at the service center specifically pay extra to switch to run-flat tires. The sidewalls of run-flat tires are particularly thick, allowing you to drive about a hundred kilometers even if a nail punctures the tire, which is very practical for friends who often drive on highways. But regular tires paired with Tesla's tire pressure monitoring system are also very reliable. The dashboard provides real-time alerts while driving, and when I encountered a nail, the system promptly warned me, helping me avoid danger.
