The maximum pressure tolerance of the original tires equipped with the 408 is 3.0, while the body label indicates a tire pressure of 2.3. However, most car service providers recommend inflating to 2.5 as the most suitable pressure. Introduction to car tire pressure: Strictly speaking, it refers to the air pressure inside the tire. In terms of car maintenance, the engine is the heart of the car, and its damage will lead to the end of the car's life. Similarly, tire pressure is the blood pressure of the car, and the level of tire pressure plays a crucial role in the performance and power of the car. Checking tire pressure: The recommended tire pressure values from the manufacturer can usually be found in the following places: the vehicle user manual, the label near the driver's door (B-pillar), the drawer next to the driver's seat, or the fuel tank cap door.

















The recommended tire pressure range for the 408 is typically between 2.3 and 2.5 bar. Check the manual or the sticker on the door for confirmation. Maintaining this range has many benefits: if it's too low, fuel consumption increases and tires wear out faster; if it's too high, the ride becomes bumpy and uncomfortable. I make it a habit to check the tire pressure regularly with a gauge, once every three months is sufficient, and it's very simple. Additionally, seasonal changes have a significant impact. Lower the pressure slightly in summer when temperatures are high, and increase it a bit in winter for better safety.

Tire pressure is crucial for driving safety and economy. The recommended standard tire pressure for the 408 is between 2.3 and 2.5 bar. From a safety perspective, too low pressure increases braking distance and makes the car prone to skidding in rainy conditions; too high pressure reduces tire grip and compromises cornering stability. Economically, proper tire pressure can save about 10% in fuel consumption and reduce tire wear. Adjust slightly based on driving conditions: 2.3 bar when unloaded for fuel efficiency, and increase to 2.5 bar when fully loaded or driving at high speeds for enhanced stability. Regularly check tire pressure to avoid leaks due to aging tires, and develop good habits.

I always refer to the manual for the tire pressure values when driving a new car. For the 408, it's generally between 2.3 to 2.5 bar. From experience, I've learned that this can extend tire life and reduce the need for replacement by two times. Measuring with a tire pressure gauge when the car is cold is the most accurate, and checking once a month helps maintain stability. Season matters: adjust to 2.4 bar in winter to prevent underinflation, and 2.3 bar in summer to reduce bumps. For daily long-distance driving, increasing the pressure to 2.5 bar offers more peace of mind, better handling, and lower fuel consumption. Always refer to the manual details for reliability, and don't rely on feelings.
