Is a tire pressure of 200 kPa normal?
1 Answers
A tire pressure of 200 kPa is not normal; 200 kPa is slightly low. Generally, tire pressure should be between 220 kPa and 240 kPa. Tire pressure refers to the air pressure inside the tire. There is a standard tire pressure label on the rear end of the driver's side door, which indicates the pressure when the tire is cold, i.e., when the vehicle has been parked for at least three hours or driven no more than 1.6 km. The measured tire pressure under these conditions is accurate. Hazards of low tire pressure: The friction coefficient with the road surface increases, leading to higher fuel consumption; it causes the steering wheel to feel heavy and increases the risk of veering, which are factors detrimental to driving safety; it increases the movement of various parts of the tire, leading to excessive rolling and abnormal heating of the tire; it reduces the functionality of the cords and rubber, causing delamination or cord breakage, excessive friction between the tire and the rim, resulting in damage to the bead area and abnormal wear. The friction between the tire and the ground increases exponentially, causing the tire temperature to rise sharply, the tire to soften, and its strength to drop drastically. If the vehicle is driven at high speeds, this may lead to a tire blowout; it increases the deformation of the tire body, making the tire sidewalls prone to cracking, while also causing flexing movements that lead to excessive heat, accelerating rubber aging, fatigue in the cord layers, and cord breakage. It also increases the tire's contact area with the ground, accelerating wear on the tire shoulders.
