What is the normal tire pressure range for a Buick Excelle?
1 Answers
The factory-recommended tire pressure standard for the Buick Excelle is 2.3-2.5. The maximum should not exceed 3.0, and the minimum should not be lower than 2.1, both of which fall within the normal range. Below is some knowledge related to tire pressure: 1. The standard tire pressure is usually indicated on the driver's side door or door frame. It's important to note that pressure can be expressed in different standard units, typically 3-4 types. Just as weight can be measured in kilograms or jin, tire pressure gauges also display 3-4 different units, such as kg/cm2, bar, PSI, and kpa. 2. The conversion relationship between these units is: 1bar=1.02kg/cm2=102kpa=14.5PSI. Car owners don't need to worry about how to calculate this; they just need to observe where the pointer on the pressure gauge points, note the unit used, and then check the vehicle's corresponding standard pressure value in that unit. 3. Nowadays, many tires are not filled with air. For these tires, the pressure requirements are more stringent. For tires filled with air, the pressure may vary with seasonal changes. Moreover, tire pressure is closely related to vehicle performance, such as comfort and load capacity, and can also affect tire lifespan. 4. Pressure is the lifeblood of tires; both excessive and insufficient pressure will shorten the tire's service life. Insufficient pressure increases tire body deformation, making the sidewalls prone to cracks and causing bending movements, leading to excessive heat, rubber aging, fatigue in the cord layer, and cord breakage. It also increases the tire's contact area with the ground, accelerating shoulder wear. Excessive pressure causes excessive stretching and deformation of the tire cords, reducing the tire body's elasticity and increasing the load on the vehicle while driving. In case of impact, it may cause internal cracks and bursts. Additionally, excessive pressure accelerates tread wear and reduces puncture resistance.
