I drove a distance when the tire was flat, Can it still be used? How should I check?

The tire is punctured, and at first no one noticed it. As the air pressure gradually decreases, cars with tire pressure monitoring systems will sound an alarm, and the driver can know it immediately. But many cars do not have tire pressure monitoring, and some drivers do not notice or feel any abnormalities when the tires are flat, which can lead to a situation where the tires are flat and they continue to drive.

    Everyone knows that when a tire runs out of air, it cannot be driven, but when a tire runs out of air, it cannot be detected immediately. If the vehicle continues to drive for a certain distance, will this cause damage to the tire? Can the tire still be used after being inflated? If the tire pressure is close to zero, driving a distance will most likely render it unusable. If there is still a little air pressure, it depends on how far you have traveled. You need to remove the tires and check them to determine if they can be used.

      Why is the tire deflated after driving a distance, and then the tire becomes useless? Due to excessive deformation on the side of the tire and repeated bending, the main cause is the excessive bending amplitude. Repeated bending can generate high temperatures, accelerate rubber aging, exceed the fatigue strength of rubber, and gradually detach from the ply layer, causing complete tire damage. Just like holding an iron wire, repeatedly and quickly bending it will also break, which is the same principle. In addition, when the tire runs out of air, the edge of the wheel hub is directly pressed against the tire. Due to the small contact area, the pressure is too high, which can crush the rubber of the tire, like a knife cutting the tire.

How to check if the tire is completely damaged? Before removing the tire, observe the side of the tire to see if there are any abnormalities, such as being worn around by road bumps or other objects. If there is, it means that the tire must not be usable and can be replaced directly. If not, further inspection needs to be conducted by going to a tire shop or repair shop to remove the tire from the wheel hub, check for any loose rubber particles on the inside, and check for any injuries on the inside. If there is, it cannot be used. When driving two to three kilometers with zero tire pressure, there will be a large amount of rubber particles falling off inside the tire. At this time, the tire will be completely scrapped, and continuing to use it is highly likely to cause a tire blowout. Tires have a crucial impact on driving safety, so once a tire runs out of air and travels a distance, it must be carefully checked and not blindly inflated before continuing to use.

How can one know if a tire is flat without tire pressure monitoring? Firstly, we need to develop good driving habits. Before driving, take a look around the car, and the key is to check if the tires are still inflated. Sometimes when a tire is punctured, we don't know. If the car is parked for two days, it will run out of air. Taking a look before driving can prevent the tire from running out of air and continuing to drive, and the tire will not be damaged. Secondly, the vehicle may also experience abnormalities when driving, such as unstable direction and deviation. This phenomenon is particularly noticeable when braking, and the car feels unstable and sways left and right. When driving the car, you will clearly feel that it is different from usual. If you feel these abnormalities, there is no fault light on the instrument panel. The first consideration is the tire pressure issue, and you should stop and check it in a timely manner.
