How to deal with a flat tire in driving? The best way to reduce your risk

Flat tire is one of the main causes of truck accidents. In daily operation, how should owners reduce the risk of blowout and ensure driving safety?

What should I do after a flat tire?

In a variety of truck tire accidents, the driver is often too nervous to handle improperly, do not know how to properly operate to avoid risk, subconsciously take some incorrect remedial measures, such as turning the steering wheel, emergency braking, etc., which may cause the vehicle trailer axle to lose control and overturn.

Once you have a flat tire, be calm. If the steering shaft tire burst during the driving process, be sure to grip the steering wheel, control the direction of the vehicle, release the accelerator, but do not step on the brake, wait until the direction of the vehicle is stable, and then slowly step on the brake, and observe the surrounding road conditions, open the double flash, tap the direction to pull over and stop.

If it is the drive axle or trailer tire burst, the first thing to do is also to grip the steering wheel, control the direction of the vehicle, avoid other collisions, pull over the brakes, and place a triangle warning sign behind the vehicle.

After an accident on the highway, we must remember the 9-word formula: "Pull over, people evacuate, that is, the alarm", because the highway driving speed is very fast, a little mistake will cause a secondary accident.

In fact, when a flat tire accident occurs, the most important thing is to grip the steering wheel! Many drivers will be shaken because of a flat tire, hands off the steering wheel, resulting in uncontrolled direction. This also tells us that we must grip the steering wheel at all times when driving daily, always be vigilant, safety is not a temporary move, a moment can not be loosened.

Why did the flat tire happen? How to prevent it on a daily basis?

In order to reduce the probability of puncture accidents, we must first understand the main causes of puncture in the daily operation:

1, tire quality is not up to standard; In order to save costs, many owners will choose to buy some of the quality of the three no tires or refurbished tires, or will choose to "sew and repair for three years", many times to repair cracked tires, etc., and these tires are easy to burst when used for a long time.

Solution: When purchasing tires, it is best to choose high-quality products through regular channels, and the quality is guaranteed. In addition, tire cracks and other problems, to promptly go to a reliable repair station or repair point to deal with, do not repair themselves at will, trailer axle if the tire is repaired many times, and the steel wire layer is damaged, it is best to replace it in time, do not have a lucky mind to continue to use.

2. Excessive tire wear or presence of foreign bodies; In daily loading, different coaxial loads lead to different friction between the tire and the ground, plus some wrong operations in the daily driving process, such as braking, rapid acceleration, etc., may cause excessive wear of a tire; Or in the process of driving, some foreign bodies stuck in the tire pattern, such as nails, stones and other sharp objects, will also increase the risk of puncture.

Solution: Check the tire condition regularly, if there is a crack or bulge, indicating that the tire is in poor condition, need to be replaced in time, especially the tire side bulge, indicating that the cord inside the part has been broken, may burst at any time.

In addition, it is necessary to do a good job of four-wheel positioning and replace the tire position according to the different wear conditions of the tire. If a tire is found to be excessively worn, it can be replaced by referring to the tire wear mark. If the tire tread is worn to the same level as the mark, the tire needs to be replaced.

Every time before the car, try to circle the car for a week, check whether there are foreign bodies on the tire, whether there are cracks, etc., and eliminate hidden dangers in time. In the process of driving, try to avoid improper operations such as sudden braking, and learn to drive with foresight. When encountering some bumps or large pits, try to slow down to reduce the damage to the tire.

3, tire pressure is too high or too low. Excessive tire pressure will lead to hard tires, reduced elasticity and shock absorption performance, reduce the contact area with the ground, and reduce the friction coefficient; The tire tire pressure is too low will lead to soft tires, tires in the case of underpressure, will be larger than the normal pressure deformation, will make the shoulder/side of the tire produce greater deformation, continuous deformation, will cause internal structure fatigue and local temperature rise, more than the critical point is easy to cause a tire burst.

Solution: In the daily operation to check the tire pressure regularly, in addition to the measurement of tire pressure needs to be carried out at room temperature, just stopped in the hot tire state, the measurement results are not accurate. And according to the requirements of the vehicle manual to maintain the standard tire pressure, remember not to ignore the spare tire pressure, in case of unexpected circumstances need to replace the spare tire.

Keep these artifacts ready to ease the risk

With the development of commercial vehicle technology, the safety configuration of tires has been further strengthened in recent years, the following three kinds of gods can effectively reduce the risk of puncture, many medium and high configuration models can be factory optional, we can consult dealers in detail when buying cars, for safety.

1, tire pressure monitoring system; As mentioned above, the tire pressure is too high or too low, there will be a risk of blowout, tire pressure monitoring system can monitor the tire pressure, temperature, etc., for the tire pressure is too high, too low, air leakage, high temperature and other special conditions for early warning, timely detection of danger signals, and timely treatment, the risk of blowout in the cradle. In fact, in addition to the factory standard, owners can also carry out later installation.

2, burst tire emergency device; If the tire pressure monitoring system belongs to trailer axle the active protection equipment, and the tire burst emergency device is a passive protection device, which can become a powerful defense line to protect the owner in the event of a tire burst.

The tire burst emergency device is called the tire anti-trip ring device. When the tire burst or pressure loss occurs, it can make the tire have a certain support, prevent the tire from getting involved in the bottom of the groove or from the steel ring, and also avoid the skid of the wheel directly contacting the ground, so that the driver can better control the direction, ensure the normal driving direction, and avoid the collision and other problems.

3. Central charging and discharging system; Tire pressure monitoring system can monitor the condition of the vehicle tire at any time, but after monitoring problems, the driver needs to manually adjust the tire pressure. The central charging and discharging system can combine the two kinds of work of monitoring tire pressure and adjusting tire pressure, automatically adjust the tire pressure according to the driving condition of the vehicle and the ambient temperature, so that the tire has been in a good working state, reduce the risk of blowout, and extend the service life of the tire and reduce fuel consumption.

Tires are the main components of the vehicle, playing a vital role in the process of vehicle driving, and the blown tire wind is also a very lethal truck accident, in the daily operation of the owners to carefully check, predictable driving, pay attention to the use of tires, improve safety.
