How long can you drive with a blown run-flat tire?

You can drive for about one hour with a blown run-flat tire, but the speed needs to be maintained at 80 kilometers per hour. The technical name for a run-flat tire is a 'deflation-proof tire,' which works by using thickened rubber sidewalls. Even if the tire loses air pressure, the sidewalls can support the vehicle's weight without causing severe deformation, so a blowout won't seriously affect driving. Run-flat tires consist of an outer tire, a standard inner tube, a spare inner tube, a steel rim, a gas generator or air chamber, a pressure sensor, and a control unit. Precautions to prevent run-flat tire blowouts include: 1. Using low-pressure tires; 2. Strictly avoiding speeding; 3. Regular tire rotation; 4. Performing dynamic balance tests.

I just dealt with a similar issue a few days ago. My friend's car was using run-flat tires, and one suddenly blew out on the highway. Their car could still drive slowly to the nearest repair shop, about 30 kilometers away. Run-flat tires are designed for this situation—they can theoretically support driving 50-80 kilometers after a complete loss of pressure, but the speed must not exceed 80 km/h. Going faster than this can easily cause the wheel to lose balance, which is very dangerous. Driving too long on a flat can deform or damage the rim, making repairs expensive and troublesome. My advice is that if a tire blows out, immediately slow down and pull over to check, then try to drive within 50 kilometers to a professional shop for a tire change. Regular maintenance shouldn’t be neglected—for example, check tire pressure monthly, inspect tire wear indicators, and avoid sidewall cracks. These small habits can significantly reduce accidents and make driving safer.

When helping out at the auto shop, I often encounter drivers bringing in cars with flat tires. Run-flat tires can indeed continue driving after a puncture, typically lasting 50-80 kilometers, but with a speed limit below 80km/h. Exceeding this speed or driving further increases the risk of damaging the rims, which can be costly to replace. It's safest to drive to a repair shop as soon as possible, keeping the distance under 50 kilometers. During the drive, actions should be gentle—minimize turns, acceleration, and avoid bumps. After a flat, it's best to drive in a low gear to reduce vibration damage to the vehicle. Don't forget to conduct a thorough inspection afterward to ensure no hidden issues remain. Safety first—it's crucial to develop the habit of regularly checking your tires.

I just learned how to drive and I'm particularly worried about tire blowouts. I heard that if a run-flat tire bursts, you can still drive 50 to 80 kilometers, as long as the speed is limited to under 80. I would immediately stop to check the extent of the damage and call for a tow truck or assistance, avoiding long-distance driving. Safety is the top priority, especially for inexperienced drivers like me. Driving too long might cause more severe damage to the car, leading to higher repair costs and affecting the vehicle's condition. It's advisable to always carry emergency contact numbers, stay calm when problems arise, and handle them step by step. Learn more about your vehicle's characteristics and regularly check tire pressure and wear to prevent similar incidents.
