What is the tire pressure for the Buick Excelle GT?
2 Answers
The normal tire pressure range for the Excelle GT is 2.4-2.5bar. Due to seasonal factors, the tire pressure can be appropriately increased by 0.2bar in winter and decreased by 0.1bar in summer. This data follows the international GBT2978-2008 standard. The tire pressure monitoring data for the Excelle GT is displayed on the central dashboard screen. If you don't have a pressure gauge, you can access the tire pressure monitoring system to check the current tire pressure values by operating the combination switch located on the left rear side of the steering wheel to bring up the tire pressure monitoring system interface. Generally, a tire pressure above 2.8bar is considered too high, and a tire pressure below 2.0bar 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 wear on the central tread pattern, 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 friction 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; weakens the function of cords and rubber, leading to delamination or cord breakage and excessive friction with the rim, causing damage to the bead area and abnormal wear; multiplies friction with 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 usually due to one of the following three reasons: Abnormal tire pressure: Typically, it will alert if the pressure is below 1.8bar or above 3.0bar. 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 indicator to light up. Simply perform a tire pressure reset to resolve this. Damaged tire pressure sensor: The tire pressure sensor, used to monitor tire pressure, is installed inside the tire and connected to the tire inflation valve. If the sensor is damaged during driving, it will also trigger the tire pressure warning light. For sensor damage issues, the only solution is to replace it with a new part.
I've been driving the Buick New Excelle for three years, and tire pressure really depends on the situation. Generally, it's recommended to maintain around 2.3 to 2.5 bar when the tires are cold, which can be found on the label on the door frame or in the manual. I make slight adjustments based on the season during daily use—reducing it to about 2.2 bar before high-speed driving in summer to prevent blowouts, and inflating to 2.6 bar in winter for better traction. It's best to keep a portable air pump in the trunk; I check it every month, especially during seasonal changes. Keeping the front tires slightly higher than the rear tires by no more than 0.3 bar can improve steering precision. Remember to increase the pressure by about 0.2 bar when carrying heavy loads—once, I didn't adjust the pressure during a fully loaded road trip, and the tire wear was noticeably uneven.
