Is 220 kPa Tire Pressure Too Low for the Excelle?
1 Answers
The tire pressure of 220 kPa for the Excelle is considered low. The normal tire pressure range for motor vehicles is between 230 kPa and 250 kPa. Both below and above this normal range can affect the vehicle's driving performance. Hazards of Low Tire Pressure Increased friction coefficient with the road surface, leading to higher fuel consumption; Causes the steering wheel to feel heavy and prone to deviation, which are 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, and excessive friction with the rim, resulting in damage to the bead area and abnormal wear; Multiplies the friction between the tire and the ground, causing a sharp rise in tire temperature, softening the tire, and drastically reducing its strength. High-speed driving under these conditions may lead to tire blowouts; Increases tire body deformation, making the tire sidewalls prone to cracking, while generating flexing movements that cause excessive heat, accelerating rubber aging, fatigue of the cord fabric layer, and cord breakage. It also increases the tire's contact area with the ground, accelerating wear on the tire shoulders.
