Why does Mercedes-Benz display the message 'Correct Tire'?
2 Answers
Mercedes-Benz displaying the message 'Correct Tire' indicates that there may be an issue with the tire pressure. Below is relevant information about automotive tire pressure: 1. Hazards of low tire pressure: Insufficient pressure increases tire deformation, leading to cracks on the sidewalls and causing flexing movements. This results in excessive heat generation, accelerating rubber aging, fatigue in the cord layers, and cord breakage. It also increases the tire's contact area with the ground, speeding up shoulder wear. 2. Hazards of high tire pressure: Excessive pressure overextends the tire cords, reducing the tire's elasticity and increasing the load on the vehicle during driving. In case of impact, it may cause internal cracks or even blowouts. Additionally, high pressure accelerates tread wear and reduces puncture resistance.
Last time I drove my Mercedes, the dashboard displayed a prompt to calibrate the tires, which usually indicates a deviation in tire pressure. The Mercedes has this feature because its intelligent system monitors the air pressure in each tire. If it detects that a tire's pressure is abnormally high or low, it will alert you to manually adjust or reset it. There could be several reasons for this: tire pressure drops when the weather gets cold and the tire volume contracts, or rises too much after being exposed to the summer sun; or you may have just replaced a new tire but didn’t reset the system, so the sensor didn’t update the data; another possibility is that bumps on the road or prolonged driving caused cumulative pressure changes leading to a false alarm. For safety, I pulled over immediately, used the onboard tire pressure monitoring function to check which tire was abnormal, then went to a gas station to adjust it back to the standard value using an air pump, and finally pressed the reset button in the car's system. If this prompt appears frequently, it’s best to conduct a thorough inspection to prevent bigger hidden dangers, as tire issues, if left unaddressed, can affect braking distance or even lead to the risk of a blowout, endangering driving safety.
