There should only be a 0.1bar difference in tire pressure between the front and rear tires of a car. Hazards of excessive tire pressure: The friction and adhesion of the tires will decrease, affecting braking performance; It can cause steering wheel vibration and deviation, reducing driving comfort; Accelerates wear on the central tread pattern of the tire, shortening tire lifespan; Increases body vibration, indirectly affecting the lifespan of other components; Overextends the tire cords, reducing tire elasticity and increasing the load on the car during driving; Reduces 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 insufficient tire pressure: Increases the friction coefficient 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 abnormal heating due to excessive rolling; Reduces the functionality of the cords and rubber, causing delamination or cord breakage and excessive friction with the rim, damaging the bead area and causing abnormal wear; Multiplies the friction between the tire and the ground, sharply increasing tire temperature, softening the tire, and drastically reducing its strength. High-speed driving may lead to blowouts; Increases tire body deformation, making the sidewalls prone to cracks and causing flexing movements that lead to overheating, accelerating rubber aging, cord fatigue, and breakage, while also increasing the tire's contact area and accelerating shoulder wear.
