At present, it is more affordable to install a tire pressure system to prevent punctures in cars?

At present, many imported models have been equipped with tire pressure systems, such as Volkswagen CC, Platinum, Emgrand EC718, Magotan, Roewe 550, and the new LaCrosse. As far as I investigated:

China: In 2011, the Ministry of Transport passed regulations on bus heights starting May 1.

Second, the third year of high school vehicles are forced to install a tire pressure monitoring system. The formulation of national standards for TPMS products has been completed, and relevant bills will be issued ...... soon

United States: In 2000, the United States passed the TREAD Act, which requires that by 2007, all cars sold in the United States must be equipped with tire pressure monitoring systems;

European Union: Since 2012, it has become mandatory for all types of new cars to be equipped with low rolling resistance tires (LRRT) and equipped with tire inspection systems.

At present, other monitoring indicators on the car instrument such as fuel tank, door, engine, brakes, etc. have only no tire monitoring indicators, and tires are the most need to protect, he is directly related to the safety of the car just like human legs, and many years of traffic accidents mostly involve tires, blood lessons so that the relevant departments have to pay attention to the safety of tires, some developed countries on the detection of tires safety distance legislation is enough to show the importance of tires, and the quality of the tire pressure system is very important, At present, there are few domestic manufacturers with relative strength, I know that the tire pressure system of this brand of Luxi is relatively iron, and the price of Huaxin is higher, Luxi manufacturers have 7 years of research and development experience and have passed various authoritative certifications such as FCC and other authoritative certification products are exported to many overseas countries, if you have any other questions, you can consult the helm manager of the East China Office: 025-6661625-800

Custard's Iron General's is better, and it can't be argued.

Most punctures are caused by low tire pressure, not high tire pressure or a puncture in the road.

When the vehicle is driving without air (tire pressure is lower than the standard tire pressure), as the tire pressure drops, the friction between the tire and the ground increases exponentially, the tire temperature rises sharply, the tire becomes softer, and the strength decreases sharply. In this case, if the vehicle is driving at high speeds, it may lead to a puncture; If the vehicle is driving at low speed, it will also hurt the tire, and the incubation period is long, the concealment is large, and it is more harmful, which buries the hidden danger of tire puncture when driving at high speed in the future.

Therefore, a flat tire is precisely due to insufficient tire pressure. The tire pressure monitoring system can be installed to know the pressure status of the tire in advance.

If you want to guarantee a sudden air leak, it is best to use a tire run-flat system, such as Tyrone's, which can only be prevented by ordinary TMPS.

1) Direct tire pressure monitoring system.

The direct tire pressure monitoring device is a system that uses the pressure sensor installed in each tire to directly measure the air pressure of the tire, and uses a wireless transmitter to send the pressure information from the inside of the tire to the first receiver module, and then displays the air pressure data of each tire. When the tire pressure is too low or flat, the system will automatically alarm.

Direct TPMS is more accurate and can also provide immediate warning if a punctured tyre is triggered and the pressure drops rapidly. In addition, even if the tires are slowly deflated, the direct tire pressure monitoring system can also sense through the driving computer, directly allowing the driver to check the current tire pressure numbers of the four tires from the driver's seat, so as to know the real air pressure status of the four wheels in real time.

2) Indirect tire pressure monitoring system.

The indirect tire alarm system actually relies on calculating the rolling radius of the tire to monitor the air pressure. It uses the speed sensor on the car's ABS braking system to compare the number of turns of four tires, and if one of the tires has a low pressure, the number of turns of this tire will be different from the others. Using the same sensors and sensing signals as the ABS system, a new function can be created on the on-the-go computer to warn the driver of a low tire pressure compared to the other three by adjusting the software on the in-vehicle computer.

Therefore, the indirect tire pressure monitoring system uses a relatively economical cost to achieve the purpose of monitoring tire pressure.

The main role of the tire pressure monitoring system is.

1) Prevent accidents.

A tire pressure monitoring system is a type of active safety device that can alert the driver to take appropriate measures when there are dangerous signs in the tire, thus avoiding serious accidents.

2) Extend tire life.

With a tire pressure monitoring system, we can keep the tires working within the specified pressure and temperature range at all times, so as to reduce tire damage and extend the life of the tires. Some data show that when driving when the tire pressure is insufficient, when the wheel pressure drops by 10% compared to the normal value, the tire life is reduced by 15%.

3) It is more economical to use a car.

When the air pressure in the tire is too low, it will increase the contact area between the tire and the ground, thereby increasing the frictional resistance, when the tire pressure is 30% lower than the standard air pressure value, the fuel consumption will increase by 10%.

4) Reduce suspension wear.

When the air pressure in the tire is too sufficient, it will lead to the reduction of the shock absorption effect of the tire itself, thereby increasing the burden of the vehicle's shock absorption system, and long-term use will cause great damage to the engine chassis and suspension system; If the tire pressure is uneven, it is also easy to cause brake mistracking, which increases the wear of the suspension system.

Isn't there something in it?

Flat-proof tires need to be pressed, which is basically the same as ordinary tires

1. The tire pressure of a run-flat tire is actually the same as that of an ordinary tire. The tire pressure is about, according to the principle of thermal expansion and cold contraction, it can be lower than the normal value in summer and higher than the normal value in winter;

2. The standard barometer can usually be found in the following places: the vehicle user manual, the label next to the cab door (near the B-pillar), the drawer next to the driver's seat of the vehicle, the small door of the fuel tank cover, and the side of the side of the passenger door. Different models have different weights and different tires.

The front and rear wheels are generally not the same;

3. The scientific name of run-flat tire is "run-flat tire", and the English abbreviation is RSC. In layman's terms, a run-flat tire is not that it will not blow out, and tire manufacturers are suspected of exaggerating the run-flat function, but its thickened rubber sidewall, even if it loses air pressure, the sidewall can support the weight of the vehicle and will not cause serious deformation of the tire wall.

No. The temperature of the tire with low tire pressure is more likely to rise, because the contact area with the ground is large, and the ply layer inside is excessively deformed. Under the vigorous deformation movement, the inner liner inside the carcass will generate high heat, which will cause the rubber and ply layers to peel off, and the risk of puncture will soar.

Moreover, the tire pressure does not only affect the contact area and position of the tire with the ground, but also affects its own shape, especially the tire sidewall, which is the weakest point of the tire.

When the sidewall touches the ground, it will deform, causing the tire to not rotate stably during driving. When the tire pressure is too low, the tire or even the hail will twist and deform irregularly in all directions on the road. The ply layer inside is constantly squeezed and rubbed and will break, resulting in bulges and punctures.

The phenomenon of vehicle puncture is what every driver does not want to see in the process of driving, because the tire is a car, a very important part, a good tire, can ensure the comfort of the vehicle during driving. However, when the weather is cold, or some external factors cause the tire pressure of the car to be too high or the tire pressure is too low, it is easy to cause a tire puncture, and compared with high tire pressure and low tire pressure, low tire pressure is more likely to puncture. <>

1. Low tire pressure in automobiles is easy to punctureAccording to relevant data, about 90% of flat tires are due to low tire pressure during normal road driving. Because now in summer, the air temperature is relatively high, this high temperature season, the temperature on the ground is also rising in a straight line, so many drivers are particularly afraid of thermal expansion and contraction in the process of driving, afraid that when the weather is hot, the gas in the tire expands and causes the tire pressure to be too high, so they will deliberately lower the tire pressure of the car. While this does reduce the tire pressure of the car, it can lead to insufficient tire pressure in the car, which can eventually lead to a puncture.

The driver must adhere to the principle of moderation when adjusting the tire pressure, if the tire pressure is too low, the weight of the air in the tire should be transferred to the tire, at this time the tire may be deformed, when the vehicle is driving at high speed, the tire will be repeatedly crushed somewhere, and then there will be damage and puncture. <>

2. How to avoid a punctureWhen the majority of car owners use the car, they must regularly maintain the vehicle and check their tire pressure regularly, because generally when using the car, we will not deliberately increase the tire pressure to the tire, so the situation of high tire pressure is relatively rare, most car owners will reduce the tire pressure, and the tire pressure will increase the risk of puncture, so the owner had better maintain his tires regularly, inflate the tires regularly, and check the tire pressure regularly, so as to avoid the phenomenon of tire aging and puncture. It is best to check 4 tires before getting on the car every time, and if you encounter low tire pressure, you should also replenish the air in time. <>

High tire pressure is easy to puncture, because of high tire pressure, the heat generated by the tire and the ground when the vehicle is driving will further increase due to the relationship between thermal expansion and contraction, and it is easy to puncture.

High tire pressure is more likely to blow up, because the tire pressure is high, and the contact between the tire and the ground is relatively small, and the air pressure in the tire is very explosive at this time, which is more likely to burst the tire.

I think it's more likely to blow out if the tire pressure is high, because if the tire pressure is high, it is likely that the car will not start at all and the tire will blow up.

It is easier to have a high tire pressure**, because the friction between the tire pressure and the ground will be greater, which will produce more force, and it is easy to puncture.

It must be that cars with higher tire pressure are more likely to have a puncture, because the tire pressure is too high, due to the backlog, and then it will **.

High or low tire pressure will be prone to punctures.

Tire pressure is too high: Once the tire exceeds the standard tire pressure, the impact resistance of the internal ply layer will decrease. In the case of high temperature and high speed, there is indeed a high possibility of a puncture in high-pressure tires.

In addition to the tire pressure factor, the tire temperature is also an important factor affecting the safety of the tire. In the case that the outside temperature is beyond our control, we should try to control the temperature of the tires not to heat up quickly, so when we park, avoid parking in an unobstructed place exposed to the sun.

Low tire pressure: Low tire pressure is more common. When the pressure of an individual tire has dropped to 2rap, it will greatly affect the life of your tire.

Once the tire pressure is lower than 2rap, the contact area between the tire and the ground will increase due to the weight of the vehicle. In addition to making it more frictional, it will also make the tires hotter. The more the sidewall bulges outward, the greater the curvature.

The healthy stress point of the tire has been destroyed. This is an important reason why low tire pressure is easy to cause punctures.

Summer is about to begin, and the chance of a tire puncture is much greater when the weather is hot, so how to prevent a puncture?
