What is the standard tire pressure for Audi A4?

[LaAustin]

The standard tire pressure for Audi A4 is to maintain the tire pressure of all four tires between 2.4-2.5bar. Due to seasonal factors, the tire pressure can be appropriately increased by 0.2bar in winter and reduced by 0.1bar in summer. This data complies with the international GBT2978-2008 standard. If you want to check the current tire pressure of your Audi A4 during daily driving, you can activate the tire pressure monitoring system, and the tire pressure values will be displayed on the central LCD screen of the instrument panel. The specific method is to click the "CAR" button on the instrument panel to view the tire pressure status. To reset the tire pressure, after clicking "CAR," rotate the central circular button to access the maintenance reset interface. Generally, a tire pressure exceeding 2.8bar is considered too high, while a tire pressure below 2.0bar is considered too low. 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; overextends tire cords, reducing elasticity and increasing the load on the vehicle during driving. Hazards of under-inflation: Increases friction coefficient with the road surface, leading to higher fuel consumption; makes the steering wheel heavy and prone to deviation, compromising driving safety; increases movement of various tire parts, causing abnormal heat due to excessive rolling; degrades cord and rubber functions, leading to delamination or cord breakage and excessive friction with the rim, damaging the bead area and causing abnormal wear; multiplies friction between the tire and ground, rapidly increasing tire temperature, softening the tire, and drastically reducing strength. High-speed driving may result in a tire blowout. If the tire pressure monitoring indicator light comes on (a yellow symbol with an irregular circle, no seal on top, four small spikes below, and an exclamation mark inside), it generally indicates one of the following three reasons: Abnormal tire pressure: Usually alarms when pressure is below 1.8bar or above 3.0bar. In this case, tire inspection and pressure adjustment are required. Tire pressure monitoring not reset: After inflating the tires, if the tire pressure is not reset in time, the system still records the previous data, causing the indicator light to illuminate. Simply perform a tire pressure reset 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 due to impact while driving, the tire pressure warning light will turn on. For sensor damage, the only solution is to replace it with a new one.
