Causes of Flat Tire
The causes for the Flat tire One of the reasons: The tire is too old In fact, there are only a few reasons for the Flat tire. The first thing that bears the brunt is that the tire has not been replaced in time after it has reached the replacement standard or has been damaged. In general, if you drive 1,200-15,000 miles per year, the tires can last for 3-5 years. By the way, teach you a way to identify the age of the tire. There is a four-digit DOT number on the tire. The first two digits are the number of weeks, and the last two digits are the year. For example, if the DOT is 1109, then the tire was produced in the 11th week of 2009. In fact, many times the tires are ok because of the long-term use, but the internal structure is damaged or has passed the tire’s own wear indicator. Such tires are very dangerous in driving.
So, at least every six years, 60,000 miles to replace a tire is very important!
The second reason: sidewall damage
Another reason is also very common, that is, some owners of the car, due to driving problems, hit the road, causing damage to the sidewall of the tire, but not leaking. In order to save money on new tires, the owner chose not to change tires and continue to use them, which is very dangerous. Because the weakest part of the tire is the side wall, it may be a little damaged on the surface, but the side wall is very thin, and the range of pressure is reduced, which is also likely to cause danger.
Once you feel the side wall is getting worn, be sure to check if there is a problem with the tire.
The third reason: too high tire pressure
Another reason is that the tire pressure is too high or too low, many riders can understand the tire pressure is too high and causes of Flat tire. When the tire pressure is higher than the normal level, the temperature of the vehicle will increase during high-speed driving, the gas will expand and contract, and the pressure will increase accordingly, causing the tire to deform and with its own elasticity to decrease, if it encounters external force. Impact, bumps, then puncture is very easy to happen, in addition, exceeding the speed limit of the tires will also increase the temperature rise, especially dangerous, so speeding is also an important hidden danger of Flat tire.
It is necessary to measure the tire pressure frequently to prevent the risk of excessive fetal pressure.
The fourth reason: tire pressure is too low
The reason why the tire pressure is too low is somewhat difficult to understand. The tire pressure is too low, which may cause the “harmonic vibration” of the carcass, causing a very large resonance force. On the other hand, the low pressure will also deform the tire. It is easy to cause the sidewall of the tire to touch the ground. As mentioned earlier, the sidewall of the tire is the most vulnerable part of the tire. Therefore, the combination of the two causes will result in the tire pressure being too low and the Flat tire. The last case is that during normal driving, the tire is scratched by a high-speed roadbed or scratched by a sharp object. This is an accident and occurs by chance.
Ways to prevent Flat tire
The very simple purpose of preventing Flat tire is to observe and test. Pay more attention to the state of your tires during normal times, and observe whether your tires have reached the wear indicator line. The tire wear indicator line is generally a flat rubber belt that is vertically embedded in the tread groove in the longitudinal direction of the tire surface, and the tire is in low wear. In the state of the wear, the wear indicator line is hardly noticed. If one or two indicator lines appear on the tire, it indicates that the tire tread has worn out very badly and the tire must be replaced immediately.
In addition, when the sidewall of the vehicle tire is damaged, it must be replaced, not because the number of kilometers of the tire is small. It is also important to note that the car tire pressure must always be controlled within the correct range according to the instructions. Also try to avoid driving beyond the speed level of the tire and avoid tire damage.
Finally, buying tires must go to a formal place to buy regular tires. The investment in tires is more important than any other investment in the car.
What should I do if I have a Flat tire?
Low-speed Flat tire, low-speed Flat tire In fact, the most important thing is to pay attention to the distance of the rear car, not because of their Flat tire, a foot brake, resulting in rear-end collision. After the low-speed Flat tire, be sure to ensure the safety of the front, rear, left and right, drive the car to the side of the road, open the double flash, set up the triangle according to the traffic regulations, replace the tires or wait for rescue. The Flat tire at a relatively high speed is a bit complicated, so let’s focus on the following.
At the higher speed, the Flat tire is divided into two cases, one is the front tire and the other is the rear tire. After the front tire Flat tire, the vehicle will produce some vehicle tilt, which makes it difficult to control the direction. At this time, it is necessary to keep calm, hold the steering wheel, adjust the front of the vehicle slightly, and the movement should not be too large, so that the vehicle can keep track of the driving track. You can’t repeatedly hit the steering wheel because the direction of the car changes, which will cause the vehicle to lose control. The rear tire Flat tire is better than the front tire Flat tire because the rear wheel itself does not have a guiding function. As long as it is not a heavily modified vehicle, the vehicle body does not have a large tilt, so the problem is not serious.
In fact, no matter when the Flat tire, remember not to slam the brakes, you need to hold the steering wheel, turn on the double flash, wait until the speed of the vehicle slows down and drive the car to the side of the road, open the double flash, set up the triangle according to traffic regulations. Replace the tires or wait for rescue.
