What is the normal tire pressure for an Audi A3?

[LeAshley]

The normal tire pressure range for an Audi A3 is 2.4-2.5 bar. Due to seasonal factors, the tire pressure can be appropriately increased by 0.2 bar in winter and reduced by 0.1 bar in summer. This data is based on the international GBT2978-2008 standard. If you want to check the current tire pressure of your Audi A3 during daily driving, you can activate the tire pressure monitoring system. The tire pressure value will then be displayed on the central LCD screen of the dashboard. You can adjust and view the real-time tire pressure and temperature using the buttons on the multifunction steering wheel. Additionally, when the tire pressure is insufficient, a warning light will appear on the dashboard to alert you. Generally, a tire pressure above 2.8 bar is considered too high, and a tire pressure below 2.0 bar is considered too low. Hazards of overinflated tires: Reduced friction and adhesion of the tires, affecting braking performance; Causes steering wheel vibration and deviation, reducing driving comfort; Accelerates wear on the central tread of the tire, shortening its lifespan; Increases vehicle vibration, indirectly affecting the lifespan of other components; Overextends the tire cords, reducing elasticity and increasing the load on the vehicle during driving. Hazards of underinflated tires: Increases friction with the road surface, leading to higher fuel consumption; Makes the steering wheel heavy and prone to deviation, compromising driving safety; Increases movement of tire components, causing excessive rolling and abnormal heating; Weakens the function of cords and rubber, leading to delamination or cord breakage and excessive friction with the rim, damaging the tire bead and causing abnormal wear; Multiplies friction with the ground, sharply raising tire temperature, softening the tire, and drastically reducing its strength. High-speed driving may lead to a blowout. If the tire pressure monitoring indicator light comes on (a yellow symbol with an irregular circle, no stamp on top, four small spikes below, and an exclamation mark inside), there are generally three possible reasons: Abnormal tire pressure: Usually triggers an alarm when below 1.8 bar or above 3.0 bar. In this case, the tires need to be checked and the pressure adjusted. Tire pressure monitoring not reset: After inflating the tires, if the tire pressure monitoring system is not reset in time, it will still record the previous data, causing the indicator light to stay on. Simply reset the tire pressure monitoring system to resolve this. Damaged tire pressure sensor: The tire pressure sensor, installed inside the tire and connected to the inflation valve, monitors tire pressure. If the sensor is damaged during driving, the tire pressure warning light will come on. In this case, the only solution is to replace the sensor with a new one.
