According to the international standard GBT2978-2008, the standard tire pressure for C260L is 2.4-2.5bar. In winter, the tire pressure should be adjusted slightly higher by about 0.2bar based on the standard tire pressure. In summer, the tire pressure can generally be about 0.1bar lower than the standard to prevent tire blowouts due to high temperatures. Tire pressure reset method: First, turn on the ignition switch, then press and hold the tire pressure monitoring reset button until you hear a "ding" sound, then release it. The tire pressure monitoring system will store the current normal tire pressure data and automatically clear the previous data. Finally, the fault light on the dashboard will go out, indicating the tire pressure reset is complete. There are generally three reasons for abnormal tire pressure: Abnormal tire pressure: The system will alert if the pressure is generally 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 reset is not performed in time, the tire pressure monitoring system will still record the previous data, causing the tire pressure monitoring indicator light to illuminate. Simply perform a tire pressure reset to resolve this issue. Damaged tire pressure sensor: The tire pressure sensor, which is used to monitor tire pressure, is directly installed inside the tire and connected to the tire inflation port. If the tire pressure sensor is damaged during driving, it will also cause the tire pressure fault light to illuminate. For sensor damage, the only solution is to replace it with a new component.

















I've been driving a C260L for several years, and the normal tire pressure range is approximately 2.3 to 2.5 bar for the front tires and around 2.2 to 2.5 bar for the rear tires. The exact values should be checked in the vehicle manual or on the label on the door B-pillar, where they are clearly stated. Don't think higher is better—too much pressure makes the tires stiff, leading to a bumpy and uncomfortable ride. Low tire pressure is even worse, increasing fuel consumption, accelerating tire wear, and even affecting braking safety. I recommend checking the cold tire pressure once a month, especially when temperatures fluctuate, to maintain stability. If the load is heavier, such as when the car is fully occupied, the pressure can be adjusted slightly higher, but for daily driving, stick to the standard values.

As a C260L owner born in the 1990s, I maintain tire pressure between 2.2 to 2.5 bar. The easiest way is to check the small label on the car's door jamb - it shows the recommended values, so don't skip reading it. If the pressure is too high, you'll feel every road bump transmitting to your bones; too low, and you'll get increased tire friction, higher fuel consumption, and faster wear. Mercedes comes with a TPMS (Tire Pressure Monitoring System) - when the dashboard warning light comes on, address it immediately. In summer when temperatures rise, tire pressure tends to increase, so I prefer measuring it when the tires are cold using a basic tire pressure gauge.

I use a C260L for my daily commute, and setting the tire pressure around 2.4 bar works just fine. Remember to check it when the tires are cold, as the reading can change in high temperatures. Low tire pressure increases braking distance and poses risks, while too high pressure makes driving uncomfortable. Checking it quarterly is beneficial for maintaining the right balance effortlessly.

The normal tire pressure range for the C260L is 2.2 to 2.5 bar, depending on usage. If frequently carrying heavy loads, such as family trips, slightly higher pressure is recommended. The simplest way is to check the vehicle manual and don't overlook the label on the B-pillar. Low pressure can cause tires to overheat, accelerate wear, waste money, and compromise safety.

I enjoy delving into car details. The standard tire pressure for the C260L is 2.3-2.5 bar for the front tires, and similar for the rear tires. Measuring under cold conditions ensures accuracy. The tire pressure monitoring system is very useful, but don't rely on it entirely. Setting it at 2.4 bar is common; too high makes the tires stiff and bumpy, while too low increases fuel consumption. Don't forget regular maintenance.
