What is the normal tire pressure for a BMW 5 Series?

[LaHaven]

BMW 5 Series normal tire pressure is between 2.2bar and 2.5bar. If the tire pressure is too low, the braking distance will be correspondingly shorter, and the grip will be better when turning, but low pressure will make the car more fuel-consuming. During driving, too low tire pressure will cause the fragile sidewall of the tire to continuously compress and restore, which can easily cause tire fatigue and accelerate temperature rise. At a certain temperature, it may cause a tire blowout. According to the provisions and requirements of the international GBT2978-2008 standard, the tire pressure for different tires is as follows: Standard tires: 2.4-2.5bar; Reinforced tires: 2.8-2.9bar; Maximum pressure: should not exceed 3.5bar. Hazards of too low tire pressure: The friction coefficient with the road surface increases, leading to higher fuel consumption; Causes the steering wheel to become heavy and prone to deviation, which are factors detrimental to driving safety; Increases the movement of various parts of the tire, and excessive rolling causes abnormal heating of the tire; Reduces the function of the cord and rubber, causing delamination or cord breakage, and excessive friction with the rim leading to damage and abnormal wear at the bead area; The friction between the tire and the ground increases exponentially, the tire temperature rises sharply, the tire softens, and the strength drops sharply. When the vehicle is driving at high speed, it may cause a tire blowout; Increases the deformation of the tire body, making the sidewall prone to cracks, while generating flexural motion, leading to excessive heat, promoting rubber aging, cord fatigue, and cord breakage. It also increases the contact area of the tire, accelerating shoulder wear.
