What is the normal tire pressure for Mercedes-Benz E300L?

[OJason]

The normal tire pressure range for Mercedes-Benz E300L is 2.4bar-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 is based on the international GBT2978-2008 standard requirements. If you want to check the current tire pressure of your Mercedes-Benz E300L 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 CAR button on the left combination instrument of the steering wheel to switch to the tire pressure monitoring system interface. Generally speaking, a tire pressure exceeding 2.8bar is considered too high, while a tire pressure below 2.0bar is considered too low. Hazards of overinflated tires: 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 deformation of tire cords, reducing tire elasticity, and increasing the load on the vehicle during driving. Hazards of underinflated tires: Increased friction coefficient with the road surface, leading to higher fuel consumption; causing heavy steering and deviation, posing risks to driving safety; increased movement of various parts of the tire, leading to abnormal overheating due to excessive rolling; reduced functionality of cords and rubber, causing delamination or cord breakage and excessive friction with the rim, resulting in damage to the bead area and abnormal wear; exponentially increased friction between the tire and the ground, rapid rise in tire temperature, softening of the tire, and sharp decline in strength. High-speed driving may lead to tire blowout. If the tire pressure monitoring indicator light comes on (a yellow symbol, an irregular circle without a seal at the top and four small spikes at the bottom, with an exclamation mark inside), there are generally three reasons: Abnormal tire pressure: Usually, an alarm will sound if the pressure is below 1.8bar or above 3.0bar. At this time, 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 tire pressure monitoring system will still record the original data, causing the tire pressure monitoring indicator light to come on. Simply perform a tire pressure reset. Damaged tire pressure sensor: The tire pressure sensor is used to monitor tire pressure and is directly installed inside the tire, connected to the tire inflation port. If the tire pressure sensor is damaged during driving, the tire pressure fault light will also come on. For sensor damage issues, only a new replacement part can be installed.
