What Causes Incorrect Tire Pressure Display When the Check Shows No Issues?

[McKatherine]

Tire pressure display showing abnormal readings when the check reveals no issues is due to: false alarms from the tire pressure monitoring system. When the vehicle is driven on gravel or slippery roads, if a certain wheel experiences slippage, causing significant differences in the rotational speeds of the four wheels, the system may mistakenly interpret this as low tire pressure in the slipping wheel. Reasons for the tire pressure warning light to illuminate include: 1. A punctured tire; 2. Excessive tire pressure; 3. Prolonged driving with low tire pressure; 4. Malfunction of the tire pressure sensor; 5. Infrequent inflation leading to decreased tire pressure. The hazards of excessive tire pressure are: 1. Reduced tire friction and adhesion, affecting braking performance; 2. Increased steering wheel vibration and deviation, lowering driving comfort; 3. Accelerated wear of the central tread pattern, shortening tire lifespan; 4. Increased vehicle vibration, indirectly impacting the longevity of other components.
