What is the normal tire pressure for Mercedes-Benz E-Class?
1 Answers
The tire pressure for Mercedes-Benz E-Class should be between 2.4-2.5 bar. Due to seasonal factors, the tire pressure can be increased by 0.2 bar in winter and decreased by 0.1 bar in summer. This data is based on the international standard GBT2978-2008. The tire pressure of the Mercedes-Benz E-Class is displayed on the multifunction screen, between the two dials. It will show the tire pressure and issue a warning if the pressure is too high or too low. The standards for too high or too low are based on the safe tire pressure set by the owner. Generally, a tire pressure exceeding 2.8 bar is considered too high, and a tire pressure below 2.0 bar is considered too low. Hazards of overinflated tires: Reduced friction and adhesion of the tires, affecting braking performance; causes steering wheel vibration and deviation, reducing driving comfort; accelerates localized wear of the tread center, shortening tire lifespan; increases vehicle vibration, indirectly affecting the lifespan of other components; overstretches the tire cords, reducing 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; causes heavy steering and deviation, posing safety risks; increases movement of tire parts, leading to abnormal heat due to excessive rolling; reduces the functionality of cords and rubber, causing delamination or cord breakage and excessive friction with the rim, damaging the tire bead and causing abnormal wear; multiplies friction between the tire and the ground, sharply raising tire temperature, softening the tire, and drastically reducing strength. High-speed driving may lead to tire blowouts. If the tire pressure monitoring indicator lights up (a yellow symbol, an irregular circle with no seal on top and four small spikes at the bottom, with an exclamation mark inside), there are generally three possible reasons: Abnormal tire pressure: Usually, an alarm is triggered when the pressure is below 1.8 bar or above 3.0 bar. In this case, the tire needs to be checked and the pressure adjusted. 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 to light up. Simply reset the tire pressure. 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 during driving, the tire pressure warning light will illuminate. For sensor damage, the only solution is to replace it with a new one.
