How many kilometers can you drive after a run-flat tire blows out?

After a run-flat tire blows out, you can still drive for about 80 kilometers, which is approximately one hour. However, it's important to note that if the run-flat tire is completely damaged, safety should still be a priority while driving. Run-flat tires are technically called "Tire Pressure Monitoring System" tires, abbreviated as RSC. The advantage of run-flat tires is that in the event of a tire leak, even if the air pressure inside the tire is completely lost, you can continue to drive at a speed of 80 kilometers per hour without immediately replacing the tire. Although run-flat tires can reduce the impact of a blowout on driving, in cases of excessive tire pressure or extreme conditions, the tire can still blow out. The difference is that after a blowout, the vehicle won't immediately stall, but you still need to drive at a limited speed, and the distance you can continue to drive is relatively limited.
As a veteran driver with decades of experience, I believe run-flat tires can still be driven for a short distance after a blowout, but don't expect too much. Run-flat tires are designed to keep going when deflated, allowing you to reach a safe location, typically for about 80 kilometers, with speed preferably kept below 80 km/h. This distance is affected by speed, vehicle load, and tire condition—driving slower can extend the range. I've experienced this myself; when my tire blew out, I drove carefully home, covering 70 kilometers, and the tire sidewall was nearly worn through. Continuing to drive too far after a blowout is risky, as it can completely ruin the tire or lead to loss of control, especially on mountain roads or in rain or snow. So my advice is: once a tire blows out, immediately slow down, turn on hazard lights, try not to drive more than 50 kilometers, and prioritize finding a professional repair shop. Don't forget to regularly check tire pressure—good habits can prevent trouble.
Speaking of run-flat tires and blowouts, I have a personal story to share. Once, while on a road trip, I suddenly had a tire blowout and had to keep driving on the run-flat tire. Based on experience, these tires are designed to run 50 to 100 kilometers after losing air, but the actual distance depends on your speed and the load in the car. I was driving at around 70 km/h with camping gear and luggage, barely making it 60 kilometers to a repair shop in town. The tire sidewall was buzzing the whole way, reminding me not to push it further. My advice is: run-flat tires aren’t a miracle cure—they’re just for emergencies. Once a tire blows, try to minimize your distance, ideally keeping it under 60 kilometers. If it happens on the highway, pulling over and calling for help is the safer move. In general, I recommend not relying on them for too long—keeping your tires in good condition is what really matters.
