Audi car tire pressure is normal between 2.3-2.5 bar, with summer tire pressure recommended to be maintained at 2.3 bar and winter at 2.5 bar. According to the international GBT2978-2008 standard, the tire pressure for different tires is as follows: Standard tires: 2.4-2.5 bar; Reinforced tires: 2.8-2.9 bar; Maximum pressure: Should not exceed 3.5 bar. Hazards of over-inflation: 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 elasticity and increasing load during driving; Decreases puncture resistance, making tires more susceptible to punctures from sharp objects like nails or glass, leading to internal cracks or blowouts. Hazards of under-inflation: Increases friction with the road surface, raising fuel consumption; Causes heavy steering and deviation, compromising driving safety; Increases movement of tire parts, leading to abnormal heat from excessive rolling; Reduces cord and rubber functionality, causing delamination or cord breakage and excessive friction with the rim, resulting in bead damage and abnormal wear; Multiplies friction with the ground, rapidly increasing tire temperature, softening the tire, and drastically reducing strength. High-speed driving may lead to blowouts; Increases tire deformation, causing sidewall cracks and excessive heat from flexing, accelerating rubber aging, cord fatigue, and breakage, while also enlarging the contact area and speeding up shoulder wear.
