Will the Tire Pressure Alarm Go Off If It's Too High?
2 Answers
Tire pressure that is too high will trigger an alarm, at which point the tire pressure monitoring indicator light will illuminate. The tire pressure monitoring indicator is a yellow symbol, an irregular circle with no seal at the top and four small spikes at the bottom, containing an exclamation mark inside. The hazards of excessively high tire pressure include: Reduced tire friction and adhesion, affecting braking performance; Causes steering wheel vibration and deviation, reducing driving comfort; Accelerates uneven wear on the central tread pattern of the tire, shortening tire lifespan; Increases vehicle body vibration, indirectly affecting the lifespan of other components; Causes excessive stretching and deformation of the tire cords, reducing tire elasticity and increasing the load on the vehicle while driving; Decreases puncture resistance. When encountering sharp objects like nails or glass on the road, they can easily penetrate the tire, leading to internal cracks and blowouts, resulting in a tire burst.
After spending a long time in the car enthusiast circle, I've become particularly sensitive to tire pressure issues. Most vehicles' Tire Pressure Monitoring Systems (TPMS) are primarily designed for low-pressure alerts, and they don't always warn about overinflation unless it's a rare advanced system that detects high-pressure deviations. Overinflated tires are usually the result of driver negligence, such as excessive air filling or temperature-induced expansion. This condition accelerates center tread wear, worsens shock absorption, reduces grip, and may even increase the risk of blowouts at high speeds. A tire blowout leading to loss of vehicle control is no minor incident—I've witnessed such accidents firsthand. So don't rely solely on warning systems—they're not always reliable. For daily driving, I make it a habit to check tire pressure monthly with a gauge, adjusting to the recommended values on the door jamb sticker (typically 2.3-2.5 bar). This practice also saves fuel, protects tires, and extends their lifespan—a true win-win. Once it becomes routine, the risk is virtually eliminated.
