What is the minimum tire pressure generally not allowed to be below?
1 Answers
There are specified values for car tire pressure. The standard tire pressure for passenger cars is within the range of 2.3-2.5 bar, with a maximum not exceeding 3.0 and a minimum not below 2.1. Hazards of 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, among other factors detrimental to driving safety; Increases the movement of various parts of the tire, causing abnormal heating due to excessive rolling; Reduces the functionality of the cord and rubber, leading to delamination or cord breakage, excessive friction with the rim, resulting in damage to the bead area and abnormal wear; The friction between the tire and the ground multiplies, causing a sharp rise in tire temperature, softening the tire, and drastically reducing its strength. High-speed driving may lead to tire blowouts; Increases tire body deformation, making the tire side prone to cracks, while generating flexing movements, leading to excessive heat, promoting rubber aging, fatigue of the cord layer, cord breakage, and also increasing the tire's contact area with the ground, accelerating shoulder wear.
