What is the normal tire pressure for a BMW 530?
1 Answers
The recommended tire pressure for a BMW 530 is between 2.3-2.5 bar, but it can vary depending on specific conditions. During summer or winter, due to the principle of thermal expansion and contraction, tire pressure increases in high temperatures and decreases in low temperatures. Therefore, summer tire pressure should be lower than winter tire pressure. Generally, it is advised to set summer tire pressure at the lower limit of the standard range, while winter tire pressure should be slightly increased by about 0.2 bar above the standard pressure. Hazards of overinflated tires: Reduced tire friction and adhesion, affecting braking performance; Causes steering wheel vibration and drifting, reducing driving comfort; Accelerates wear on the central tread pattern, shortening tire lifespan; Increases vehicle vibration, indirectly affecting the lifespan of other components; Overstretches tire cords, reducing elasticity and increasing the load on the vehicle during driving; Decreases puncture resistance, making it easier for sharp objects like nails or glass to penetrate the tire, leading to internal cracks or blowouts. Hazards of underinflated tires: Increases friction with the road surface, leading to higher fuel consumption; Causes heavy steering and drifting, compromising driving safety; Increases movement of tire components, leading to abnormal overheating due to excessive rolling; Weakens cord and rubber functions, causing delamination or cord breakage and excessive friction with the rim, damaging the bead area; Dramatically increases friction with the ground, raising tire temperature and softening the tire, which can lead to blowouts at high speeds; Increases tire deformation, causing sidewall cracks and excessive heat, accelerating rubber aging, cord fatigue, and tread wear.
