What is the recommended tire pressure for vehicles in summer?
1 Answers
In summer, the normal tire pressure for cars is between 2.3 and 2.5. If the car is fully loaded with 5 passengers, adjusting the tire pressure to around 2.5 is more suitable; if there are generally two people, a tire pressure of 2.3 is normal. Hazards of overinflated tires: The friction and adhesion of the tires will decrease, affecting braking performance; It can cause steering wheel vibration and deviation, reducing driving comfort; Accelerates localized wear of the tread pattern in the center of the tire, shortening tire life; Increases vehicle vibration, indirectly affecting the lifespan of other components; Causes excessive stretching and deformation of tire cords, reducing tire elasticity and increasing the load on the car while driving; Decreases puncture resistance. When encountering sharp objects like nails or glass on the road, they can easily penetrate the tire, causing internal cracks or blowouts. Hazards of underinflated tires: Increases the friction coefficient with the road surface, leading to higher fuel consumption; Makes the steering wheel heavy and prone to deviation, creating unsafe driving conditions; Increases movement in various parts of the tire, causing abnormal heating due to excessive rolling; 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; 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 may lead to blowouts; Increases tire deformation, making the sidewalls prone to cracks and causing flexing movements, leading to excessive heat, rubber aging, cord fatigue, and breakage, while also increasing the tire's contact area with the ground, accelerating shoulder wear.
