What is the normal tire pressure for highway driving in summer?
1 Answers
In summer, the appropriate tire pressure for highway driving is around 2.3 to 2.5 bar. Due to the weather conditions in summer, tire pressure should not be too high to avoid blowouts during high-speed driving. Hazards of over-inflation: Reduced tire friction and adhesion, affecting braking performance; Causes steering wheel vibration and deviation, reducing driving comfort; Accelerates uneven wear on the central tread of the tire, 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 vehicle during driving; Decreases puncture resistance. When encountering sharp objects like nails or glass, the tire is more prone to punctures, leading to internal cracks or blowouts. Hazards of under-inflation: Increases friction with the road surface, leading to higher fuel consumption; Makes the steering wheel heavy and prone to deviation, compromising driving safety; Increases movement in various parts of the tire, causing abnormal heat due to excessive rolling; Weakens the function of cords and rubber, leading to delamination or cord breakage and excessive friction with the rim, causing damage to the bead area 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 with the ground, accelerating shoulder wear.
