What is the normal tire pressure for a Buick Excelle?
1 Answers
The normal tire pressure range for the Buick Excelle 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 is based on the international GBT2978-2008 standard requirements. The method to check tire pressure in the Excelle is: press the menu button to switch to the vehicle information menu, rotate the knob at the top of the left lever to the tire pressure monitoring information interface, and you can see the tire pressure of all four wheels. Generally speaking, a tire pressure exceeding 2.8 bar is considered too high, and a tire pressure below 2.0 bar is considered too low. Hazards of overinflated tires: reduced tire friction and adhesion, affecting braking performance; causing steering wheel vibration and deviation, reducing driving comfort; accelerating wear on the central tread pattern, shortening tire lifespan; increased vehicle vibration, indirectly affecting the lifespan of other components; excessive stretching of tire cords, reducing tire 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; heavy steering wheel and tendency to deviate, compromising driving safety; excessive movement of tire parts, causing abnormal heat generation; reduced functionality of cords and rubber, leading to delamination or cord breakage and excessive friction with the rim, damaging the tire bead area and causing abnormal wear; multiplied friction between the tire and the ground, sharply 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 seal on top, four small spikes below, and an exclamation mark inside), there are generally three possible reasons: Abnormal tire pressure: usually alerts when 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, the tire pressure was not reset in time, causing the system to still record the previous data, thus illuminating the indicator light. Simply reset the tire pressure 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, the tire pressure warning light will illuminate. For sensor damage, replacement with a new part is the only solution.
