Why did the tire pressure suddenly drop to 180?
1 Answers
The sudden drop in tire pressure to 180 may be due to a punctured tire. Check if there are any screws or nails stuck in it causing air leakage. It could also be caused by a leaking valve stem, which can be detected by applying soapy water on the tire to locate the leak. Another possibility is tire aging, which can be determined by checking for cracks on the tire sidewall. Hazards of excessive tire pressure: Reduced friction and adhesion of the tire, affecting braking performance; Causes steering wheel vibration and deviation, reducing driving comfort; Accelerates localized wear on the central tread pattern, shortening tire lifespan; Increases vehicle vibration, indirectly affecting the lifespan of other components; Overstretches the tire cords, reducing elasticity and increasing the load on the tire during driving; Decreases puncture resistance. When encountering sharp objects like nails or glass, the tire is more prone to punctures, internal cracks, or blowouts. Hazards of insufficient tire pressure: Increases friction with the road surface, leading to higher fuel consumption; Causes heavy steering and deviation, compromising driving safety; Increases movement in various parts of the tire, leading to excessive rolling and abnormal heat generation; Reduces the functionality of cords and rubber, causing delamination, cord breakage, and excessive friction with the rim, leading to bead damage and abnormal wear; Multiplies the friction between the tire and the ground, rapidly increasing tire temperature, softening the tire, and drastically reducing its strength. High-speed driving may result in blowouts; Increases tire deformation, making the sidewalls prone to cracks and generating flexing movements, leading to excessive heat, rubber aging, cord fatigue, and breakage. It also increases the tire's contact area, accelerating shoulder wear.
