Can a Car Spare Tire Be Used as a Lifebuoy?
1 Answers
Car spare tires cannot be used as lifebuoys. The following is relevant information about tire pressure: 1. Introduction to tire pressure: Strictly speaking, it refers to the air pressure inside the tire. Tire pressure is closely related to the performance of the car, such as comfort and load capacity, and it also affects the lifespan of the tire. 2. Hazards of low tire pressure: Insufficient pressure increases the deformation of the tire body, easily causing cracks on the tire side and generating flexing movements, leading to excessive heat, promoting rubber aging, fatigue of the cord layer, and breakage of the cords. It also increases the tire's contact area with the ground, accelerating wear on the tire shoulders. 3. Hazards of high tire pressure: Excessive pressure causes the tire cords to undergo excessive stretching and deformation, reducing the elasticity of the tire body and increasing the load on the car while driving. If impacted, it can lead to internal cracks and blowouts. Additionally, excessive pressure accelerates wear on the tire tread and reduces puncture resistance.
