What is the recommended tire pressure range for the Envision?

[Annie]

The normal tire pressure range for the Envision is 2.4-2.5bar. Due to seasonal factors, the tire pressure can be appropriately increased by 0.2bar in winter and reduced by 0.1bar in summer. This data complies with the international GBT2978-2008 standard. The Envision 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 assurance for driving. Generally speaking, a tire pressure exceeding 2.8bar is considered too high, while a tire pressure below 2.0bar is considered too low. Hazards of excessive tire pressure: The friction and adhesion of the tires will decrease, affecting braking performance; it can cause steering wheel vibration and deviation, reducing driving comfort; it accelerates localized wear of the tread pattern in the center of the tire, shortening the tire's lifespan; the vehicle's vibration increases, indirectly affecting the lifespan of other components; it can cause excessive stretching and deformation of the tire cords, reducing the elasticity of the tire body and increasing the load on the vehicle during driving. Hazards of insufficient tire pressure: The friction coefficient with the road surface increases, leading to higher fuel consumption; it makes the steering wheel heavy and prone to deviation, among other factors that compromise driving safety; it increases the movement of various parts of the tire, causing abnormal heating due to excessive rolling; it reduces the functionality of the cords and rubber, leading to delamination or cord breakage and excessive friction with the rim, causing damage to the bead area and abnormal wear; the friction between the tire and the ground increases exponentially, causing a sharp rise in tire temperature, softening the tire, and drastically reducing its strength. High-speed driving under these conditions may lead to a tire blowout. If the tire pressure monitoring indicator light comes on (a yellow symbol with an irregular circle, no stamp on top, four small spikes at the bottom, and an exclamation mark inside), there are generally three possible reasons: Abnormal tire pressure: The system usually alerts when the pressure is below 1.8bar or above 3.0bar. In this case, tire inspection and pressure adjustment are necessary. 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 indicator to light up. Simply resetting the tire pressure will resolve this issue. Damaged tire pressure sensor: The tire pressure sensor, which monitors tire pressure, is directly installed inside the tire and connected to the tire inflation valve. If the sensor is damaged due to impact while driving, it can also trigger the tire pressure warning light. For sensor damage, the only solution is to replace it with a new one.
