External or Internal Tire Pressure Monitoring: Which is Better?
1 Answers
Tire pressure monitoring systems, whether internal or external, each have their own advantages and disadvantages. The choice can be made based on the specific needs of your vehicle. Advantages and disadvantages of internal tire pressure monitoring devices: Advantages: Installed inside the tire, they replace the original valve with a sensor-equipped valve, with minimal external protrusion. Once installed, they are virtually maintenance-free (lasting over 5 years without issues). Disadvantages: Installation is complex and requires wheel balancing. Advantages and disadvantages of external tire pressure monitoring devices: Advantages: Easy installation. No need to replace the valve, no wheel balancing required, and often no need for inflation or deflation. The owner may only need to screw the sensor onto the valve. Disadvantages: Not suitable for SUVs with higher tire pressure. Inflation and deflation require removing and reinstalling the sensor. External sensors are prone to damage from foreign objects. How tire pressure monitoring works: Pressure sensors installed inside the tire measure the tire's air pressure, and a wireless transmitter sends this information from inside the tire to a central receiver module. Hazards of overinflated tires: Reduced tire friction and adhesion, affecting braking performance; Causes steering wheel vibration and misalignment, reducing driving comfort; Accelerates wear on the central tread pattern, shortening tire lifespan; Increases vehicle vibration, indirectly affecting the lifespan of other components; Overextends the tire cords, reducing elasticity and increasing the load on the vehicle during driving; Decreases puncture resistance. When encountering sharp objects like nails or glass on the road, the tire is more likely to be punctured, leading to internal cracks, blowouts, or even tire bursts.
