What is the normal tire pressure for the Envision?
2 Answers
The normal tire pressure range for the Buick 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 requirements. The Buick Envision is equipped with an active tire pressure monitoring system, allowing drivers to view specific tire pressure values directly on the dashboard. The tire pressure monitoring system automatically monitors tire pressure in real-time during driving and alerts the driver to tire leaks or low pressure to ensure driving safety. If the tire pressure monitoring indicator light illuminates (a yellow symbol featuring an irregular circle without a seal at the top, four small spikes at the bottom, and an exclamation mark inside), it generally indicates one of the following three reasons: Abnormal tire pressure. The system typically triggers an alert when the pressure is below 1.8bar or above 3.0bar. In such cases, tire inspection and pressure adjustment are necessary. The tire pressure monitoring system has not been reset. After inflating the tires, if the tire pressure reset is not performed promptly, the system continues to record the previous data, causing the tire pressure monitoring light to illuminate. Simply performing a tire pressure reset will resolve this issue. Damaged tire pressure sensor. The tire pressure sensor, installed inside the tire and connected to the tire inflation valve, monitors tire pressure. If the sensor is damaged during driving, such as by hitting an obstacle, it can cause the tire pressure warning light to turn on. In case of sensor damage, the only solution is to replace it with a new component.
I've been driving my own Envision for three years, and I find maintaining a cold tire pressure around 2.4 bar most comfortable. Before high-speed driving in summer heat, I reduce it to 2.3 to avoid the sudden scare of the tire pressure warning light; in winter, I increase it to 2.5 for a less bumpy ride over speed bumps. When the trunk is fully loaded with New Year goods, I manually adjust it up by 0.1, otherwise the tire walls look depressingly flat, making me feel particularly sorry for the tires. Last time during maintenance, the mechanic even complimented the even wear of the tire treads. The trick is actually measuring it twice a month with a mechanical gauge. The tire pressure label on the door frame has long faded from the sun, so keeping notes in a notebook is more reliable. I remember once when the tire pressure reached 3.0, hitting a pothole directly caused a bulge, and the cost of replacing a tire was enough for three tanks of gas.
