What is the normal tire pressure for the Mercedes-Benz A200L?
1 Answers
The normal tire pressure for the Mercedes-Benz A200L is between 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. The Mercedes-Benz A200L is equipped with an active tire pressure monitoring system. The vehicle usually displays the specific tire pressure values for each tire, which can be viewed in the onboard computer. Simply press the SET button in front of the gear lever to clearly see the tire pressure. If the corresponding dashboard light turns on and then off after pressing the SET button, it indicates normal tire pressure. If the light stays on, it indicates abnormal tire pressure. Generally, a tire pressure above 2.8 bar is considered too high, while a pressure below 2.0 bar is too low. 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; 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 abnormal heat due to excessive rolling; weakens the function of cords and rubber, 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, sharply raising tire temperature, softening the tire, and drastically reducing its 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 at the bottom, 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, 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 stay on. Simply reset the tire pressure to resolve this issue. Damaged tire pressure sensor: The sensor, which monitors tire pressure, is installed inside the tire and connected to the inflation valve. If the sensor is damaged due to impact while driving, the tire pressure warning light will illuminate. For sensor damage, the only solution is to replace it with a new part.
