Built-In Tire Pressure Monitoring Or External Tire Pressure

It looks beyond dispute that the tires are like the legs and feet of a car, which can't be a little bit wrong during high-speed driving. Experienced drivers get into the habit of checking the tire pressure frequently, who can not only see if the tire is running flat, but even have the capability to feel whether the tire is abnormal during driving. However, for many new generation drivers spoiled by automated equipment, it is of great significance to install a road witness tire pressure monitoring system. In terms of choosing a tire pressure monitoring device, in addition to the brand, function and price, the choice of external or built-in tire pressure monitoring usually makes drivers entangled. Therefore, today we will discuss the difference between built-in and external tire pressure monitoring.

 

External TPMS

The external car tyre pressure monitoring system is to install the sensor directly on the valve core of the original car. Many manufacturers say that external TPMS does not require balancing. When the vehicle is assembled at the factory, dynamic balance tests are performed to ensure that the wheels still reach the most stable state under high-speed driving.

 

What is dynamic balance? The wheels of a car are composed of tires and wheels. However, due to manufacturing reasons, the mass distribution of the entire parts cannot be very uniform. When the car wheels rotate at high speed, it will form a dynamic unbalanced state, giving rise to the phenomenon of wheel vibration and steering wheel vibration during the driving process. In order to avoid this phenomenon or eliminate this phenomenon that has occurred, the method, Increasing the counterweight needs to be adopted to make the wheel correct the balance of each edge part under dynamic conditions.

 

Therefore, many manufacturers will advertise that their sensors weigh only a few grams and do not require dynamic balancing，whose argument does not keep reliable. In fact, even if a logo is added to the tires of regular manufacturers, it needs to be balanced.

 

Built-In TPMS

Installing the tire pressure sensor on the wheel hub inside the tire. After installation, the tires must be dynamically balanced. At present, car owners generally say that the built-in is better, and their main reason is that the external gas-filling nozzle is inaccurate, inflated, troublesome, and easy to be stolen. As a matter of fact, most non-SUN models will not have too many problems like gasp, stolen and so on, which have a relatively low probability of occurrence. In addition, if the tire needs to be inflated, it is not complicated to screw it down and reinstall it，and moreover, the inflation of tires does not remain necessarily extremely frequent.

 

The built-in tire pressure monitoring must be selected under the conditions of SUV models, complex road conditions, and damage to the original valve. In fact, the most criticized problem of built-in tire pressure monitoring is the trouble of installation, which makes drivers usually have to go to the decoration shop to spend hours and hundreds of dollars to get it. In addition, the built-in tire pressure monitoring is generally more expensive than the external type.

 

In conclusion, the built-in tire pressure monitoring is safer and more accurate, which is not easy to be stolen and does not need to be disassembled when pumping up. In contrast, its installation is more cumbersome. The installation of external tire pressure monitoring is simple, but it is easy to fall, which needs to be disassembled every time the tire is pumped up. Besides, its monitoring data is less accurate than the built-in.
