You cannot continue driving with a run-flat tire at 0 pressure, as it compromises driving safety. The tire pressure needs to be replenished promptly. Effects of Low Tire Pressure: Low tire pressure increases the friction coefficient with the road surface, leading to higher fuel consumption. It also makes the steering wheel heavy and prone to veering, among other factors detrimental to driving safety. Additionally, it causes excessive movement in various parts of the tire, resulting in abnormal heat generation due to over-compression. This significantly multiplies friction between the tire and the ground, rapidly raising tire temperature, softening the tire, and drastically reducing its strength. High-speed driving under such conditions may lead to a tire blowout. Precautions for Inflating Tires: When inflating tires, always use a pressure gauge to monitor the pressure to avoid overinflation, which can cause the tire to burst. After stopping the vehicle, wait for the tires to cool down before inflating, as driving raises tire temperature and affects pressure. Ensure cleanliness during inflation; the air pumped in must not contain moisture or oil to prevent deterioration and damage to the inner rubber .

That day my tire pressure monitoring system suddenly alarmed, and when I got out of the car, I saw the left rear tire was completely flat. Since I was using run-flat tires, I continued driving for 20 kilometers to the repair shop as per the manufacturer's instructions. The sidewalls of these tires are reinforced, allowing them to be driven at low speeds even when flat, but the speed must be kept below 80 km/h, and sharp turns should be avoided. However, this is only an emergency solution. At the time, I could feel the steering wheel was particularly heavy, and the car body was slightly pulling to the left. Driving like this for a long time can deform the wheel rims or even damage the suspension system, so it's essential to get the tire repaired or replaced as soon as possible. I remember last time my neighbor's run-flat tire had a hole, and after stubbornly driving home, they found the inner side of the wheel rim was all scratched when replacing the tire.

It's true that you can still drive with a completely flat tire, especially since run-flat tires are designed with supporting structures. From my experience: first, slow down to below 80 km/h; second, avoid sharp turns; third, don't drive too far—the manual states 50-80 km is the limit. Although you can keep driving, the handling will feel vague, braking distance increases, and extra caution is needed, especially in rainy conditions. Once, while exiting the highway, the tire pressure warning came on. I maintained 60 mph and slowly coasted to the service area. On the way, when passing large trucks, I clearly felt the airflow pushing the car body to the right. The repair technician later said the tire sidewall steel cords had slightly deformed and continuing to drive could have ruined the tire.

Driving short distances at low speeds with zero tire pressure is possible, but don't make it a daily habit. I tried it when I had a flat tire earlier this year - drove at 60 km/h for half an hour, and the steering wheel vibrated so much it made my hands numb. Run-flat tires on their stiff sidewalls to support the vehicle, but prolonged driving causes them to overheat and deform. Once I saw a car at the neighborhood entrance with its wheel rim scraping the ground and sparking - the owner had driven too long with zero pressure. This emergency design ensures safety, but if you really get a flat, calling a tow truck is much more worry-free.

Yes, you can still drive. I experienced this just last week. During rush hour on the expressway, my front right tire went flat. I followed the car in front at 45 km/h for 3 km until I could exit the ramp. But there are three things to keep in mind: don't exceed 80 km/h; hold the steering wheel firmly; and ideally, resolve the issue within 50 km. The tire shop owner showed me with a jack—the rim was almost scraping the ground when the tire was flat. Driving too long like this will definitely damage the wheel. Their shop receives wheel rims ruined from driving with zero tire pressure every month.

Can drive short distances, but must be addressed immediately. Last year during a road trip, I ran over a nail and the dashboard showed tire pressure at 0. Following the manual, I reduced speed to 70 mph and drove 12 km to find an auto repair shop. Although drivable, the steering wheel noticeably became heavier, and the entire car shook when going over speed bumps. The mechanic warned that driving in this condition for too long could cause four-wheel alignment deviation and easily deform suspension links. They advised not to exceed 30 km even if drivable, as safety is more important than saving money.
