What is the difference between internal and external tire pressure monitoring?

[TannerAnn]

The differences between internal and external tire pressure monitoring are: 1. Price difference: Internal type is more expensive; External type is cheaper; 2. Installation time: Installing internal type takes more time and requires professionals to remove the tires; External type is simple to operate, car owners can manually replace it, which is simple and fast. The principle of internal and external tire pressure monitoring is the same, both use sensors on the wheels to detect and transmit signals via wireless transmitters to determine tire pressure. The so-called tire pressure refers to the air pressure inside the tire. When the tire pressure is too high, the vehicle's dynamic resistance is small and fuel consumption is low, but in emergency situations, sudden braking often fails to stop the car, or the braking distance is extended; When the tire pressure is too low, the vehicle's comfort is better, driving is quiet and smooth, but the rolling resistance is large and fuel consumption is high, and the vehicle is prone to standing waves and sudden tire bursts when driving at high speeds.
