What is the Appropriate Tire Pressure at 4000 Meters Above Sea Level?

[ORachel]

At an altitude of 4000 meters, the recommended tire pressure for vehicles is 2.3~2.5 bar. Hazards of Overinflated Tires: Reduced tire friction and adhesion, affecting braking performance; Causes steering wheel vibration and deviation, reducing driving comfort; Accelerates wear on the central tread pattern, shortening tire lifespan; Increases vehicle vibration, indirectly affecting the lifespan of other components; Overstretches tire cords, reducing tire elasticity and increasing the load on the vehicle during driving; Decreases puncture resistance. Sharp objects like nails or glass can easily penetrate the tire, causing internal cracks or blowouts. Hazards of Underinflated Tires: Increases friction with the road surface, leading to higher fuel consumption; Makes steering heavy and prone to deviation, compromising driving safety; Increases movement of tire components, causing abnormal heat due to excessive rolling; Weakens cord and rubber functionality, leading to delamination or cord breakage, and excessive friction with the rim, causing damage and abnormal wear; Multiplies friction with the ground, rapidly raising tire temperature, softening the tire, and drastically reducing strength. High-speed driving may result in blowouts; Increases tire deformation, leading to sidewall cracks and excessive flexing, which generates heat, accelerates rubber aging, cord fatigue, and breakage, and enlarges the tire's contact area, speeding up shoulder wear.
