I had my car tires inflated by 10-20%, and my mileage (mostly city) went from 22.5 to 25 mpg. Does this sound feasible?
Increasing tire pressure reduces the rolling resistance of the tires, which means they require less energy (and therefore, less fuel) to move forward. This ultimately leads to improved gas mileage.
The amount of improvement in gas mileage will vary depending on your specific vehicle and driving habits. However, studies have shown that increasing tire pressure by just a few pounds per square inch (psi) can result in a 3-4% increase in gas mileage.
Yes, every vehicle has a specific recommended tire pressure that can be found in the owner's manual or on a sticker inside the driver's side door. It is important to follow this recommended pressure for optimal gas mileage and tire performance.
Increasing tire pressure beyond the recommended amount can lead to overinflation, which can cause uneven tire wear and potentially damage the tires. It is important to not exceed the maximum tire pressure listed on the tire sidewall.
It is recommended to check and adjust tire pressure at least once a month to ensure it is at the recommended level. However, once you find the optimal tire pressure for your vehicle, it should remain fairly consistent unless there is a significant change in temperature or driving conditions.
