What is the normal tire pressure for a Mercedes-Benz A200?
1 Answers
The normal tire pressure range for a Mercedes-Benz A200 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. The Mercedes-Benz A200 tire pressure monitoring system is a passive monitoring type. Normally, the vehicle does not display the specific tire pressure values for each tire. The tire pressure warning light will only illuminate when abnormal tire pressure is detected. Generally, a tire pressure exceeding 2.8 bar is considered too high, while a tire pressure below 2.0 bar is considered too low. Hazards of excessive tire pressure: Reduced tire friction and adhesion, affecting braking performance; causing steering wheel vibration and deviation, reducing driving comfort; accelerating wear on the central tread pattern of the tire, shortening tire lifespan; increased vehicle vibration, indirectly affecting the lifespan of other components; excessive stretching of tire cords, reducing tire elasticity, and increasing the load on the vehicle during driving. Hazards of insufficient tire pressure: Increased friction coefficient with the road surface, leading to higher fuel consumption; causing heavy steering and deviation, posing safety risks; increased movement of various parts of the tire, leading to abnormal heat generation due to excessive rolling; reduced functionality of cords and rubber, causing delamination or cord breakage, and excessive friction with the rim, damaging the tire bead area and causing abnormal wear; exponentially increased friction between the tire and the ground, rapidly raising tire temperature, softening the tire, and drastically reducing its strength. High-speed driving may lead to tire blowouts. If the tire pressure monitoring indicator light comes on (a yellow symbol, an irregular circle with no stamp on top and four small spikes at the bottom, with an exclamation mark inside), there are generally three possible reasons: Abnormal tire pressure: Usually, the system will alert if the pressure is below 1.8 bar or above 3.0 bar. At this point, 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 will still record the previous data, causing the tire pressure monitoring indicator light to illuminate. Simply reset the tire pressure to resolve this issue. Damaged tire pressure sensor: The tire pressure sensor, which monitors tire pressure, is installed inside the tire and connected to the tire inflation valve. If the sensor is damaged during driving, the tire pressure warning light will also come on. For sensor damage issues, only a complete replacement with a new part will suffice.
