What causes the set light to illuminate on the Bora?

[DiRachel]

set light is the tire monitoring light, and the illumination of the set light on the Bora is mostly due to abnormal tire pressure. Here are some related expansion materials: 1. The relationship between tire pressure and load capacity: Tire pressure is an indicator of a car's load capacity. The size of the car's load depends on the level of tire pressure. According to the relationship between the tire's load index, tire pressure, and tire load capacity, the higher the tire pressure, the greater the load capacity, and the lower the pressure, the smaller the load capacity. 2. The relationship between tire pressure and vehicle dynamics: When a car is driving at a constant speed on a horizontal road, it must overcome rolling resistance from the ground and air resistance. Tire pressure has a significant impact on the rolling resistance coefficient. When the pressure decreases, the rolling resistance coefficient increases rapidly. This is because when the tire pressure decreases, the deformation of the rolling tire increases, leading to an increase in hysteresis loss.
