How far can a BMW drive after a flat tire?

If equipped with run-flat tires, the vehicle can still drive up to 250 kilometers after a flat tire. Causes of flat tires: Speeding, overloading, tire wear and aging, excessive or insufficient air pressure, poor tire quality, impact, tire sidewall bulging, or manufacturing defects in the tire. Why run-flat tires can continue driving: In the event of a tire leak, even if the air pressure inside the tire is completely lost, the vehicle can still continue driving at speeds up to 80 km/h without immediately needing to replace the tire. The reason run-flat tires do not collapse after losing air pressure is mainly due to their reinforced rubber sidewalls. Even without air pressure, the sidewalls can support the vehicle's weight without causing severe deformation, so a flat tire does not significantly affect the vehicle's driving performance.
I personally experienced a tire blowout once while driving a BMW, and it was truly terrifying. After a blowout, you absolutely must not drive too far because the wheel rim will directly contact the road surface, causing severe wear. Especially at high speeds, the vehicle can easily lose control, which is extremely dangerous. Many BMW models come equipped with run-flat tires, commonly known as Run-Flat tires, which allow you to drive at low speeds for about 80 kilometers after a blowout, enabling you to reach a repair shop. However, in practical terms, I recommend keeping the speed below 50 km/h and ensuring the road conditions are good. If a blowout happens on the highway, immediately turn on the hazard lights and pull over to the side. Waiting for assistance or changing to a spare tire is the safest option. Make it a habit to regularly check your tires—measure the tire pressure once a month to avoid other faults caused by driving on damaged tires. Safety first—don’t gamble with your life over small savings!
From a vehicle construction perspective, the distance a BMW can travel after a tire blowout mainly depends on the tire type. If run-flat tires are installed, their thick sidewall design can support the vehicle's weight at low speeds for about 80 kilometers, which is sufficient to reach a repair shop. With standard tires, driving even a few hundred meters after a blowout can severely damage the rims, costing thousands more. Driving conditions also affect the distance: for example, at low urban speeds, the tire may last slightly longer, while at high speeds, the tire can overheat rapidly. My personal advice is to stop and inspect immediately after a blowout—although BMW's run-flat system is effective, risks remain, especially when losing tire pressure on curves, which can lead to skidding. Regular tire replacement can prevent such issues; generally, tires last about 5 years, and replacing them when the tread wears out saves money and ensures peace of mind.
As a BMW owner who commutes daily, I've experienced a tire blowout before. That time it happened on the highway when I wasn't driving fast, so I dared not exceed 60km/h and managed to drive about 3 kilometers before pulling over. BMW's run-flat tires theoretically allow for 80 kilometers of driving, but actual road conditions and weather are crucial: wet roads in rain shorten the distance, and the rims and suspension can suffer impact deformation. It's recommended to immediately slow down and find a safe place to change to the spare tire or call for a tow truck. Regular tire maintenance, like checking tire pressure during each service, can significantly reduce the chance of a blowout. In emergencies, don't push your luck—getting home safely is what matters most.
