How Much Does Tire Pressure Increase When Driving on the Highway?
1 Answers
Normally, the standard tire pressure for cars is around 2.4-2.5 bar, and it increases by approximately 0.4-0.6 bar when driving on the highway. Hazards of Overinflated Tires: Reduced friction and adhesion of the tires, affecting braking performance; Causes steering wheel vibration and deviation, reducing driving comfort; Accelerates localized wear of the tread center, 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. Sharp objects like nails or glass can easily penetrate the tire, leading to internal cracks, blowouts, or even tire bursts. Hazards of Underinflated Tires: Increases friction with the road surface, raising fuel consumption; Makes the steering wheel heavy and prone to deviation, compromising driving safety; Increases movement of tire components, causing abnormal heat due to excessive rolling; Weakens the function of cords and rubber, leading to delamination, cord breakage, or excessive friction with the rim, damaging the bead area and causing abnormal wear; Multiplies friction with the ground, rapidly increasing tire temperature, softening the tire, and drastically reducing strength. High-speed driving may result in tire bursts; Increases tire deformation, making the sidewalls prone to cracks. Flexing movements generate excessive heat, accelerating rubber aging, cord fatigue, and breakage, while also enlarging the tire's contact area and accelerating shoulder wear.
