Why Does Tire Pressure Drop After Parking When It's Normal While Driving?

[OElena]

There are two main reasons for a sudden tire pressure warning. The first reason is uneven tire pressure distribution, where one tire's pressure is too low, causing the tire temperature to rise during high-speed operation and leading to increased pressure. In this case, it is necessary to stop and rest promptly or replace the spare tire. The second reason is a slow tire leak, which can be checked using a tire pressure gauge. If the tire is low on air, inflate it and then monitor the tire pressure warning light. Hazards of Low Tire Pressure Increased friction with the road surface, leading to higher fuel consumption; Heavier steering wheel and a tendency to drift, which are factors detrimental to driving safety; Increased movement of various parts of the tire, causing abnormal heat due to excessive rolling; Reduced functionality of the cords and rubber, leading to delamination or cord breakage, excessive friction with the rim, resulting in damage to the bead area and abnormal wear; Exponentially increased friction between the tire and the ground, causing a sharp rise in tire temperature, softening of the tire, and a rapid decrease in strength. High-speed driving under these conditions may lead to a tire blowout; Increased deformation of the tire body, making the sidewalls prone to cracks and inducing flexing movements, which generate excessive heat, accelerate rubber aging, fatigue the cord layers, and break the cords. It also increases the tire's contact area with the ground, accelerating wear on the tire shoulders.
