What is the normal tire pressure for a Mercedes GLC260?
1 Answers
The normal tire pressure range for a Mercedes GLC260 is 2.4bar to 2.5bar. Due to seasonal factors, the tire pressure can be appropriately increased by 0.2bar in winter and decreased by 0.1bar in summer. This data is based on the international GBT2978-2008 standard requirements. The GLC260's tire pressure monitoring is passive and does not display specific values. It only alerts on the dashboard when the tire pressure is abnormal. Generally, a tire pressure exceeding 2.8bar is considered too high, while a pressure below 2.0bar is too low. Hazards of overinflated tires: Reduced friction and adhesion, affecting braking performance; causes steering wheel vibration and misalignment, reducing driving comfort; accelerates wear on the central tread pattern, shortening tire lifespan; increases vehicle vibration, indirectly affecting other components' longevity; overstretches tire cords, reducing elasticity and increasing load during driving. Hazards of underinflated tires: Increased friction with the road surface, leading to higher fuel consumption; makes the steering wheel heavy and prone to misalignment, compromising safety; increases movement in tire parts, causing abnormal heat from excessive rolling; weakens cord and rubber functionality, leading to delamination or cord breakage and excessive friction with the rim, damaging the bead area and causing abnormal wear; multiplies friction with the ground, rapidly raising tire temperature, softening the tire, and drastically reducing strength. High-speed driving may result in a blowout. If the tire pressure monitoring indicator lights up (a yellow symbol with an irregular circle, no stamp on top, four small spikes below, and an exclamation mark inside), it is generally due to one of three reasons: Abnormal tire pressure: Typically alerts when below 1.8bar or above 3.0bar. Immediate tire inspection and pressure adjustment are required. Tire pressure monitoring not reset: After inflating the tires, failing to reset the tire pressure monitoring system, which still records the previous data, causing the indicator to light up. Simply reset the tire pressure. Damaged tire pressure sensor: The sensor, installed inside the tire and connected to the inflation valve, monitors tire pressure. If damaged during driving (e.g., by impact), it triggers the warning light. A damaged sensor must be replaced.
