Why is the tire pressure requirement for the Vezel so low?
2 Answers
Tire pressure should not be lower than the recommended value for half load, and not higher than the recommended value for full load. Within this range, adjustments can be made according to daily load, road conditions, and requirements for comfort, fuel consumption, etc. The tire pressure should be set according to the manufacturer's recommended value: The manufacturer's recommended tire pressure can usually be found in the vehicle's user manual, on the label next to the driver's door, in the drawer next to the driver's seat, or on the fuel tank cap. The manufacturer's recommended tire pressure refers to the cold tire pressure: Measured after the vehicle has been parked for at least 3 hours or if the tires have not been driven more than 2 kilometers. If tire pressure must be measured when the tires are hot, subtract approximately 0.3 bar (=4psi) from the measured value to obtain the cold inflation pressure.
With over a decade of experience in auto repair, I've worked with tire settings across various vehicle models. The Vezel's lower tire pressure requirement primarily stems from its suspension design prioritizing comfort. As a compact SUV, engineers opted for lower tire pressure to allow the tires to better absorb road vibrations, resulting in a smoother ride, especially in urban areas or on rough roads. Additionally, the tire size and contact patch design provide improved traction at lower pressures, enhancing stability during turns. Data shows that slightly lower tire pressure increases fuel consumption marginally but optimizes balance tests, making it ideal for daily use. Just a reminder to owners: excessively low pressure may accelerate edge wear and risk wheel deformation, while overinflation leads to a harsher ride. I recommend monthly checks with a tire gauge when the tires are cold, maintaining values within the manual's range. Avoid overfilling in summer to prevent thermal expansion from exceeding limits. Developing this habit ensures worry-free driving.
