Why is the tire pressure always insufficient?
2 Answers
Tire pressure is always insufficient due to abnormal tire pressure, unreset tire pressure monitoring, or damaged tire pressure sensors. Abnormal tire pressure: Generally, an alarm will sound when the pressure is below 1.8 bar or above 3.0 bar. At this point, tire inspection and pressure adjustment are required. Unreset tire pressure monitoring: After inflating the tires, if the tire pressure monitoring system is not reset in time, it will still record the previous data, causing the tire pressure monitoring indicator light to illuminate. Simply reset the tire pressure monitoring to resolve this issue. Damaged tire pressure sensor: The tire pressure sensor, installed inside the tire and connected to the tire inflation valve, monitors tire pressure. If the sensor is damaged during driving, the tire pressure warning light will turn on. For sensor damage, the only solution is to replace it with a new one.
Ever since I started driving, I've noticed that my tire pressure is often too low. Nine times out of ten, it's due to slow leaks caused by nails puncturing the tires or roadside broken glass. Even sand and stones on the road can pose hidden risks. Temperature and weather have a significant impact—summer heat causes obvious expansion and contraction, and sudden temperature drops lead to decreased tire pressure, especially noticeable in spring and autumn. Tires also naturally lose air over time due to rubber aging or wear on the valve's sealing ring, creating small leaks. Harsh vibrations from driving over potholes can accelerate this issue. I've also observed a more than 10% increase in fuel consumption, along with uneven tire wear, which raises the risk of blowouts. For safety, I bought a tire pressure gauge and now make it a habit to check monthly, adjusting the pressure at home or using free equipment at gas stations. I pay extra attention during seasonal changes and always ensure proper tire pressure before long trips—it saves fuel costs and gives me peace of mind on the road.
