Attention, car owners! Driving safety is of utmost importance. As the only part of the vehicle that contacts the ground, the tire’s condition is directly related to driving safety, so many car owners will choose a tire pressure monitoring system. But when choosing a tire pressure monitoring system, it is difficult to choose between built-in and external types. Let’s talk about the differences between the two today.

Let’s talk about the built-in type first. The sensor is installed at the valve stem inside the tire, monitoring tire pressure and temperature data and transmitting wirelessly to the receiver in the car. It is highly accurate, safe, and beautiful, but it is complicated to install. It needs to be operated by a professional shop and dynamic balancing is required, which is expensive. It is also troublesome to replace the battery when it is exhausted.

For the external type, the sensor is installed on the outside of the valve stem and tightened. It is easy to install, the battery is easy to replace, and the price is affordable, but the measurement accuracy is slightly poor, there is a risk of theft, and it affects the appearance.

If you focus on long-term stability and accuracy, and don’t mind complex installation and high costs, you can choose the built-in type; if you pursue convenience and cost-effectiveness, and don’t have high requirements for accuracy, the external type is a good choice. In short, choosing according to your needs can help you drive safely.
