What is the Optimal Tire Pressure for Fuel Efficiency?
1 Answers
Tire pressure and fuel consumption are inversely proportional—higher tire pressure leads to lower fuel consumption. However, as tire pressure decreases, the rate of increase in fuel consumption becomes more gradual. In practical experience, a range of 2.4-2.6 Bar is optimal. Fuel efficiency still largely depends on individual driving habits. 1. If the car is fully occupied (5 people), adjusting the tire pressure to around 2.5 Bar is advisable; for two passengers, a tire pressure of 2.3 Bar is also normal. 2. Standard tire pressure can usually be found in the following locations: 3. The vehicle's 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.
