What is the difference between built-in and external tire pressure monitoring?
3 Answers
The differences between built-in and external tire pressure monitoring are as follows: 1. Price difference: The built-in type is slightly more expensive than the external type. 2. Installation method: Installing a built-in tire pressure monitor takes more time and requires professional assistance to remove the tires, making it difficult for individuals to install themselves. The external type is simpler to install, allowing car owners to do it themselves. 3. Accuracy difference: Due to environmental factors and external forces, the accuracy of the external type is slightly lower than that of the built-in type. 4. Anti-theft difference: The built-in type is more secure as it is installed inside the tire, while the external type has poorer anti-theft performance. Regarding the two types of tire pressure monitoring, users are advised to choose based on their own needs.
Built-in tire pressure monitoring systems have sensors installed inside the tire, directly fixed to the wheel hub. The advantage is highly accurate measurements, real-time pressure monitoring, and resistance to theft or damage. However, installation is troublesome as it requires removing the tire at a shop, and the cost is higher. External systems have sensors clipped onto the valve stem, exposed outside. They are easy to install yourself, cheaper and more convenient, but they can slip off or get stolen easily, have larger measurement errors, and require frequent battery changes. Having driven two cars using both types, built-in is better for long-distance travel where safety is the priority, while external is more suitable for short city trips, saving money and hassle.
Tire pressure monitoring mainly comes in two types: built-in and external. Built-in sensors are installed inside the tire, mounted on the wheel hub, providing highly accurate temperature and pressure data with strong anti-interference capabilities. However, they are difficult to install and remove, requiring professional tools during maintenance, though they have a long lifespan and require less maintenance. External sensors are screwed onto the valve stem, making them easy to install and operate by oneself at a much lower cost. However, being exposed, they are prone to theft or damage, and the data can sometimes fluctuate, requiring extra attention during rainy days. Having modified several cars, I believe built-in sensors are better for those with high safety requirements, while external ones suit lazy folks—finding the right balance is key.
