Is built-in or external tire pressure monitoring better?
2 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 vehicle situation. 1. Pros and cons of built-in tire pressure monitoring devices: Advantages; Installed inside the tire, using a sensor-equipped valve stem to replace the original one, with minimal external protrusion, not extending beyond the wheel hub. Once installed, it is essentially a one-time solution (can last over 5 years without issues). Disadvantages: Complex installation process, and requires wheel balancing. 2. Pros and cons of external tire pressure monitoring devices: Advantages: Easy installation. No need to replace the valve stem, no wheel balancing required, and may not even require inflating or deflating the tire. All the owner might need to do is screw the sensor onto the valve stem. Disadvantages: Not suitable for SUV models with higher tire pressure. Inflating or deflating requires removing and reinstalling the sensor, and external sensors are more susceptible to damage from foreign objects.
As someone who frequently commutes by car, I think external tire pressure monitoring is more suitable for everyday users like me. The installation is super simple—I got it done in just a few minutes without spending money at a repair shop, making it perfect for DIY. The price is also affordable, costing just a few dozen yuan, and the money saved can be used for gas. When replacing the battery or checking, it’s easy to remove, unlike built-in monitors that require tire disassembly. The downside is that it’s exposed and could be stolen or affected by weather, but careful handling minimizes the risk. While not as precise as built-in monitors, its accuracy is sufficient for daily use, helping prevent blowouts or increased fuel consumption due to low tire pressure. While driving, I rely on a smartphone app for real-time monitoring, which is quite smart. Overall, external monitors offer great value, especially for older cars or budget-conscious owners—convenience is what truly matters.
