Is 220 kPa Tire Pressure Too Low for the Excelle?
1 Answers
An Excelle tire pressure of 220 kPa is considered low. The normal tire pressure range for vehicles is between 240 and 250 kPa. If the tire pressure of a motor vehicle is not within the normal range, it will affect the normal driving of the vehicle. During driving, the vehicle is very prone to tire blowouts, which can lead to accidents. Hazards of excessive tire pressure: The friction and adhesion of the tires will decrease, affecting braking performance; It can cause steering wheel vibration and deviation, reducing driving comfort; It accelerates the wear of the central tread pattern of the tire, shortening the tire's lifespan; The vibration of the vehicle body increases, indirectly affecting the lifespan of other components; It causes excessive stretching and deformation of the tire cords, reducing the elasticity of the tire body and increasing the load on the vehicle during driving; Puncture resistance decreases. When encountering sharp objects such as nails or glass on the road, they can easily penetrate the tire, and the impact can cause internal cracks and blowouts, leading to tire failure. Hazards of insufficient tire pressure: The friction coefficient with the road surface increases, leading to higher fuel consumption; It makes the steering wheel heavy and prone to deviation, creating factors that are unfavorable for driving safety; It increases the movement of various parts of the tire, causing abnormal heating due to excessive rolling; It reduces the functionality of the cords and rubber, leading to delamination or cord breakage, and excessive friction with the rim, causing damage and abnormal wear at the bead area; 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 can lead to tire blowouts; It increases the deformation of the tire body, making the tire side prone to cracks, and generates flexing motion, leading to excessive heat, accelerating rubber aging, fatigue of the cord layers, and cord breakage. It also increases the tire's contact area with the ground, accelerating wear at the tire shoulders.
