The normal tire pressure range for the Envision 20t is 2.4-2.5 bar. Due to seasonal factors, the tire pressure can be appropriately increased by 0.2 bar in winter and reduced by 0.1 bar in summer. This data is based on the international GBT2978-2008 standard requirements. The Envision 20t is equipped with a direct tire pressure monitoring system, and the real-time tire pressure values are displayed on the dashboard. The tire pressure monitoring technology can automatically monitor various conditions of the tires in real-time by recording the rotation speed of the tires or through electronic sensors installed inside the tires, providing effective safety protection for driving. Generally speaking, a tire pressure exceeding 2.8 bar is considered too high, while a tire pressure below 2.0 bar is considered too low. Hazards of overinflated tires: Reduced tire friction and adhesion, affecting braking performance; Causes steering wheel vibration and deviation, reducing driving comfort; Accelerates localized wear of the tread pattern in the center of the tire, shortening tire lifespan; Increases vehicle vibration, indirectly affecting the lifespan of other components; Overextends the tire cords, reducing tire elasticity and increasing the load on the vehicle during driving. Hazards of underinflated tires: Increases the friction coefficient with the road surface, leading to higher fuel consumption; Makes the steering wheel heavy and prone to deviation, compromising driving safety; Increases the movement of various parts of the tire, causing abnormal heat due to excessive rolling; Weakens the function of the cords and rubber, leading to delamination or cord breakage and excessive friction with the rim, damaging the tire bead area and causing abnormal wear; Multiplies the friction between the tire and the ground, sharply raising tire temperature, softening the tire, and drastically reducing its strength. High-speed driving may result in a tire blowout. If the tire pressure monitoring indicator light comes on (a yellow symbol with an irregular circle, no seal on top, four small spikes below, and an exclamation mark inside), there are generally three possible reasons: Abnormal tire pressure: Usually, it will alert if the pressure is below 1.8 bar or above 3.0 bar. In this case, tire inspection and pressure adjustment are required. Tire pressure monitoring not reset: After inflating the tires, if the tire pressure is not reset in time, the system will still record the previous data, causing the tire pressure monitoring light to stay on. Simply reset the tire pressure to resolve this issue. Damaged tire pressure sensor: The tire pressure sensor, installed inside the tire and connected to the tire inflation valve, monitors the tire pressure. If the sensor is damaged due to impact while driving, the tire pressure fault light will illuminate. For sensor damage issues, the only solution is to replace it with a new component.
