What Causes the Constant Illumination of the Lavida Tire Pressure Monitoring Light?

[StBriella]

The Lavida utilizes an indirect tire pressure monitoring system, and the persistent illumination of its tire pressure warning light is most likely due to forgetting to set the initial tire pressure values. Lavida's tire pressure monitoring relies on the ABS pump to detect tire rolling circumference for pressure assessment. It requires setting default values—specifically, after inflating all four tires, you must drive for a few minutes and then long-press the SET button. A confirmation 'beep' indicates the system has recorded the preset standard values. Subsequently, if any tire's pressure falls below this threshold, the system will trigger an alert. Relevant technical details: 1. Underinflation: Low tire pressure increases tire body deformation, leading to sidewall cracks and excessive flexing. This generates overheating, accelerating rubber aging, ply fatigue, and cord breakage. It also enlarges the tire's contact patch, hastening shoulder wear. 2. Overinflation: Excessive pressure overextends tire cords, reducing elasticity and increasing driving load. Impacts may cause internal fractures or blowouts, while high pressure also accelerates tread wear and compromises puncture resistance.
