What is the appropriate tire pressure for an Audi Q3?

[Joy]

The standard tire pressure for an Audi Q3 is around 2.4-2.5 bar, and it may vary slightly depending on specific conditions. During summer or winter, due to the principle of thermal expansion and contraction, tire pressure increases in high temperatures and decreases in low temperatures. Therefore, summer tire pressure should be lower than winter tire pressure. Generally, it is recommended to set the summer tire pressure at the lower limit of the standard range, while in winter, the tire pressure should be adjusted slightly higher by about 0.2 bar above the standard pressure. Both overinflation and underinflation can shorten the lifespan of the tires. Hazards of overinflation: Reduced tire friction and adhesion, affecting braking performance; Causes steering wheel vibration and misalignment, reducing driving comfort; Accelerates wear on the central tread of the tire, reducing 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 or blowouts. Hazards of underinflation: Increases friction with the road surface, leading to higher fuel consumption; Causes heavy steering and misalignment, compromising driving safety; Increases movement of tire components, leading to excessive heat generation due to over-flexing; Weakens the cords and rubber, causing delamination or cord breakage, and excessive friction with the rim, damaging the bead area and causing abnormal wear; Dramatically increases friction with the ground, rapidly raising tire temperature, softening the tire, and drastically reducing strength. High-speed driving may lead to blowouts; Increases tire deformation, causing cracks on the sidewalls and excessive flexing, leading to overheating, rubber aging, cord fatigue, and breakage. It also enlarges the tire's contact area, accelerating shoulder wear.
