Which is Better: Built-in or External Tire Pressure Monitoring?
4 Answers
Tire pressure monitoring systems, whether built-in or external, each have their own advantages and disadvantages, and the choice can be made based on the specific needs of your vehicle. 1. Pros and Cons of Built-in Tire Pressure Monitoring Devices: Pros; Installed inside the tire, using a sensor-equipped valve stem to replace the original one, with minimal exposure outside, not protruding beyond the wheel hub. Once installed, it is essentially a permanent solution (can last over 5 years without issues). Cons: Complex installation process, requiring wheel balancing. 2. Pros and Cons of External Tire Pressure Monitoring Devices: Pros: Easy installation. No need to replace the valve stem, no wheel balancing required, and not even needing to inflate or deflate the tire. All the owner might need to do is screw the sensor onto the valve stem. Cons: Not suitable for SUV models with higher tire pressure. Inflating or deflating requires removing and reinstalling the sensor, and external sensors are prone to damage from foreign objects.
I've been driving for a long time and believe built-in tire pressure monitoring is more reliable. Installed inside the tires, it's unaffected by wind or rain, providing accurate readings without worrying about false alarms compromising safety. Especially when driving on highways or long distances, incorrect tire pressure could lead to blowouts or loss of control. Built-in systems offer earlier warnings, ensuring driving safety. External ones, while easier to install, are prone to damage or theft. When I used an external one, I was always worried about the sensors getting stolen when parked, and they often gave false alarms in summer due to high temperatures. Overall, built-in systems have better durability. Though more expensive and complicated to install, safety is priceless and worth the investment. Regularly checking the tire pressure system during maintenance can enhance vehicle lifespan and fuel efficiency.
As a DIY enthusiast, I prefer external tire pressure monitors for their convenience and ease of use. Installing them myself saves a trip to the repair shop—just screw them onto the valve stem, and it's done in minutes, plus they cost less than half the price. They're perfectly adequate for daily driving, reliably monitoring tire pressure during commutes. However, if you frequently drive on rough roads or highways, external monitors may be slightly affected by vibrations, leading to minor reading deviations, and their batteries need regular replacement to prevent failure. Built-in monitors, while more accurate, require professional installation. Overall, if you're on a tight budget or a beginner, external monitors are a great choice—they're fun to install and can even be moved to other vehicles. Just remember to calibrate them regularly to ensure accuracy.
From a durability perspective, built-in tire pressure monitoring systems (TPMS) come out on top. Integrated within the wheel hub, they are collision-proof, waterproof, and dustproof, lasting three to five years or even longer with minimal maintenance costs. The sensors in my car have been functioning flawlessly for over two years. In contrast, external TPMS units are exposed to the elements, making them prone to weather-induced corrosion, requiring battery replacement or inspection every six months, and potentially dislodging on bumpy roads. Although initially more expensive to install, built-in systems prove more cost-effective long-term by eliminating roadside breakdown risks. The main advantage of external TPMS lies in their removable design, suitable for temporary needs. For tire pressure monitoring, stability is paramount – built-in systems offer superior reliability to ensure safe and efficient vehicle operation.
