Is it better to buy internal or external tire pressure monitoring?
3 Answers
Tire pressure monitoring is better to buy internal. The following are the advantages of internal tire pressure monitoring: 1. Internal tire pressure monitoring is more accurate because the sensor is inside the tire and is less affected by external environmental factors. Whether in winter or summer, there will be no deviation due to temperature. 2. Better anti-theft performance. Since the external sensor is directly installed at the valve, while the internal one is installed inside the tire, the anti-theft performance of the internal type is relatively better. 3. Convenience. The internal sensor is inside the tire, making installation more troublesome, but it is more convenient when inflating. The external type must remove the sensor when inflating, which is more troublesome, and improper operation can easily damage the sensor.
As an average family car owner who has been driving for over a decade, I initially used an external tire pressure monitoring system because it was affordable and easy to install—I could just screw it on myself. However, I later found that it was prone to theft and its accuracy was affected on rainy days, which constantly made me worry about unstable tire pressure. Last year, I switched to an internal system. Although it took some time at the shop to remove and install the tires and the cost was higher, it’s more accurate and reliable, not susceptible to theft, and the battery lasts five to six years. During my daily commute and when driving my kids to school, I feel much more at ease. The data is displayed in real-time on the dashboard, eliminating the sudden shock of alarms. I recommend prioritizing internal systems, especially in urban areas where parking safety is paramount—don’t sacrifice long-term security for short-term convenience.
I'm an automotive technology enthusiast with a decade of car experience and in-depth knowledge of tire pressure monitoring systems. The advantage of external sensors lies in their easy installation—even beginners can DIY by screwing them onto the valve stems, and they're cost-effective for budget-conscious owners. However, their exposed sensors sometimes lead to measurement inaccuracies, and they may become loose or fall off on bumpy roads. Built-in sensors, integrated inside the tires, provide precise readings, better dynamic balance, and stronger anti-theft properties, making them ideal for performance-oriented drivers or those frequently on highways. Long-term, I prefer the reliability of built-in sensors paired with real-time monitoring to prevent blowouts and ensure driving safety. They also require less daily maintenance, eliminating the need for frequent checks.
