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.
