What is the normal tire pressure for the Buick Envision?

[Pam]

The normal tire pressure range for the Buick Envision is 2.4-2.5 bar. Due to seasonal factors, the tire pressure can be appropriately increased by 0.2 bar in winter and decreased by 0.1 bar in summer. This data complies with the international GBT2978-2008 standard. The Buick Envision is equipped with an active tire pressure monitoring function, allowing you to view the specific tire pressure values directly on the dashboard. The tire pressure monitoring system automatically monitors the tire pressure in real-time while driving and alerts the driver in case of tire leaks or low pressure to ensure driving safety. Generally, 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 uneven wear of the central tread pattern, shortening tire lifespan; increases vehicle vibration, indirectly affecting the lifespan of other components; overstretches the tire cords, reducing elasticity and increasing the load on the vehicle during driving. Hazards of underinflated tires: Increased friction coefficient with the road surface, leading to higher fuel consumption; causes heavy steering and deviation, compromising driving safety; increases movement of tire components, leading to excessive rolling and abnormal heat generation; reduces the functionality of cords and rubber, causing delamination or cord breakage and excessive friction with the rim, damaging the tire bead area and causing abnormal wear; multiplies friction between the tire and the ground, sharply raising tire temperature, softening the tire, and drastically reducing its strength. High-speed driving may lead to tire blowouts. If the tire pressure monitoring indicator light illuminates (a yellow symbol with an irregular circle, no seal on top, four small spikes at the bottom, and an exclamation mark inside), it is generally due to one of the following three reasons: Abnormal tire pressure. The system usually alerts when 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 continues to record the previous data, causing the indicator light to illuminate. 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 inflation valve, monitors tire pressure. If the sensor is damaged during driving, the tire pressure warning light will illuminate. In such cases, the only solution is to replace the sensor with a new one.
