What is the standard tire pressure for the Mercedes-Benz GLA200?
1 Answers
The normal tire pressure range for the Mercedes-Benz GLA200 is 2.4-2.5 bar. Due to seasonal factors, the tire pressure can be appropriately increased by 0.2 bar in winter and decreased by 0.1 bar in summer. This data is based on the international GBT2978-2008 standard requirements. If you want to check the current tire pressure of the Mercedes-Benz GLA200 during daily driving, you can activate the tire pressure monitoring system, and the tire pressure value will be displayed on the central LCD screen of the instrument panel. The specific method is to press the LCD adjustment button on the left combination instrument of the steering wheel to switch to the tire pressure monitoring system interface. 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 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 tire 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 in various parts of the tire, causing abnormal heat due to excessive rolling; reduces the functionality of cords and rubber, leading to delamination or cord breakage and excessive friction with the rim, damaging the tire bead area and causing abnormal wear; multiplies friction between the tire and the ground, rapidly increasing 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 stamp on top, four small spikes at the bottom, and an exclamation mark inside), it generally indicates one of the following three reasons: Abnormal tire pressure: Typically alerts when pressure is 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 will still record the previous data, causing the tire pressure monitoring indicator light to come on. 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 tire inflation valve, monitors tire pressure. 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.
