Notes:
- The recommended tire pressure provided in this answer should correspond with the values mentioned in your Peugeot 308 owner's manual. It's always best to refer to the vehicle manufacturer's recommendations for specific tire pressure based on the year, trim level, and tire size equipped on your vehicle.
- Tire pressure should be measured when the tires are cold, meaning they haven't been driven on recently. Check the tire pressure every few weeks or when there is a significant change in temperature.
