Overfilling Your Tires Doesn’t Improve MPG

And did you know that overfilling your tires doesn’t actually improve your vehicle’s fuel efficiency? Many people believe that by increasing the air pressure in their tires beyond the manufacturer’s recommendations, they will be able to get better gas mileage. However, this is a common misconception that can actually be detrimental to both your tires and your wallet.

When it comes to tire pressure, it’s important to follow the guidelines set by the manufacturer. Overinflating your tires can cause a number of problems, including a rough ride, decreased traction, and increased wear on your tires. In extreme cases, it can even lead to a blowout, putting you and your passengers at risk.

Most modern vehicles are equipped with a Tire Pressure Monitoring System (TPMS) that alerts you when your tire pressure is too low. This system is designed to help you maintain the proper tire pressure for optimal performance and safety. By ignoring these warnings and overinflating your tires, you are not only risking your safety but also compromising your vehicle’s handling and fuel efficiency.

While it’s true that properly inflated tires can improve your vehicle’s fuel efficiency, there is a limit to how much you can inflate them. According to the U.S. Department of Energy, overinflating your tires by just 10% can decrease your gas mileage by up to 3%. This is because overinflated tires have a smaller contact patch with the road, which can lead to uneven tire wear and reduced grip.

In addition, overinflated tires can also result in a harsher ride and increased road noise. This is not only uncomfortable for you and your passengers but can also cause unnecessary wear and tear on your vehicle’s suspension system. By following the manufacturer’s recommendations for tire pressure, you can ensure a smoother, quieter ride and extend the life of your tires.

In conclusion, overfilling your tires may seem like a quick and easy way to save money on gas, but it can actually have a negative impact on your vehicle’s performance and safety. By following the manufacturer’s recommendations for tire pressure, you can improve your fuel efficiency without compromising your comfort or risking a blowout. Remember, proper tire maintenance is essential for a safe and enjoyable driving experience, so always make sure to check your tire pressure regularly and inflate them to the correct level. Your vehicle—and your wallet—will thank you in the long run.
