Is it better to buy built-in or external tire pressure monitoring?
2 Answers
Tire pressure monitoring is better when built-in than external, as built-in is a direct monitoring type of tire pressure monitoring, providing accurate results. The tire pressure monitoring system generally consists of a tire pressure monitoring module and four tire pressure sensors. Whether built-in or external, their sensor modules transmit data wirelessly. Information about built-in and external tire pressure monitoring is as follows: 1. Built-in tire pressure monitoring: Also known as direct tire pressure monitoring, it uses pressure sensors installed in each tire to directly measure the tire's air pressure. The system uses a wireless transmitter to send pressure information from inside the tire to a central receiver module, which then displays the tire pressure data for each tire. When the tire pressure is too low or there is a leak, the system automatically alerts, serving as a proactive defensive measure. 2. The mechanism of external tire pressure monitoring involves replacing the valve cap with a sensor, which is directly fitted onto the valve stem. By pressing the valve core inward, the internal tire pressure is released, allowing direct detection of tire pressure and temperature.
Choosing between internal or external tire pressure monitoring depends on your needs. Having driven for many years, I prefer internal sensors because they are located inside the tire, providing more accurate pressure readings with less interference from external factors like temperature changes or rain, thereby reducing the risk of blowouts. Although professional tools are required for installation, it's a one-time job that lasts 5 to 7 years with minimal daily maintenance and better anti-theft protection. External sensors screw onto the valve stem and can be installed by yourself, making them convenient for beginners, but data can fluctuate during bumpy rides, batteries last only about a year before needing replacement, and they might be easily stolen. In terms of safety, internal sensors are far more reliable, especially for long-distance highway driving, where accurate tire pressure data can prevent accidents and reduce fuel consumption. Overall, if you prioritize safety and durability, I recommend investing in internal sensors for better value.
