What is the appropriate tire pressure for the Excelle?

[OVincent]

The recommended tire pressure for the Buick Excelle is between 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 is based on the international GBT2978-2008 standard. The tire pressure monitoring system in the Buick Excelle can be viewed on the small screen in the instrument cluster. For the base model, this feature is not available. Press the "MENU" button on the turn signal lever to switch the small screen on the instrument cluster to the "Vehicle Information Menu," which has only two pages: overspeed alarm and tire pressure monitoring. The fuel mileage information menu has more content. Press the MENU button to switch to the vehicle information menu. Generally, a tire pressure above 2.8 bar is considered too high, and a tire pressure below 2.0 bar is considered too low. Hazards of overinflated tires: Reduced friction and adhesion of the tires, affecting braking performance; causes steering wheel vibration and deviation, reducing driving comfort; accelerates wear on the central tread pattern, shortening tire life; increases vehicle vibration, indirectly affecting the lifespan of other components; overstretches 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 movement in various parts of the tire, causing abnormal heat due to excessive rolling; reduces the functionality of the cords and rubber, leading to delamination or cord breakage and excessive friction with the rim, damaging the tire bead and causing abnormal wear; multiplies the friction between the tire and the ground, rapidly increasing 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 stamp 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: Usually alerts when the pressure is below 1.8 bar or above 3.0 bar. In this case, the tires need to be checked and the pressure adjusted. Tire pressure monitoring not reset: After inflating the tires, the tire pressure monitoring system was not reset in time, causing it to record the previous data and trigger the indicator light. Simply reset the tire pressure monitoring system. Damaged tire pressure sensor: The tire pressure sensor, which monitors tire pressure, is installed inside the tire and connected to the tire valve. If the sensor is damaged due to impact while driving, it will also trigger the tire pressure warning light. For sensor damage, the only solution is to replace it with a new one.
