Does Tire Pressure Have An Effect On Gas Mileage?
Most drivers don’t immediately think of their tires when trying to improve fuel efficiency, but your tire pressure plays a significant role in how much gas your Ford uses. So, does tire pressure affect gas mileage? Absolutely. Keeping the correct tire pressure is one of the easiest and most effective methods to increase MPG, enhance safety, and protect your investment—particularly if you are driving a truck, SUV, or crossover.
According to the U.S. Department of Transportation and the U.S. Department of Energy, maintaining proper tire pressure is crucial for optimizing fuel economy and preventing waste.
At Moon Township Ford, we’re committed to helping you get the most out of every fill-up. Read on to learn why proper tire pressure matters, how low tire pressure affects fuel economy, and how to find the best tire pressure for gas mileage in your Ford vehicle.
Does Low Tire Pressure Affect Gas Mileage?
Yes—low tire pressure directly reduces your fuel economy. When your tires are under-inflated, they create more resistance against the road. This increased rolling resistance makes your engine work harder, burning more fuel as a result. Driving with low tire pressure can reduce your gas mileage by more than 3%. Underinflated tires not only negatively impact fuel economy but also compromise vehicle safety and tire longevity.
For high-mileage drivers or those using work trucks like the Ford F-150, that drop in efficiency can quickly lead to more frequent trips to the gas station and unnecessary fuel costs. Plus, underinflated tires wear out faster, have poor handling, and are more prone to blowouts, especially when driving at high speeds or hauling heavy loads. Proper tire pressure ensures optimal tire contact with the road, enhancing both fuel efficiency and safety.
What’s the Best Tire Pressure for MPG?
The best tire pressure for gas mileage is usually the number recommended by your vehicle’s manufacturer. You can find this PSI (pounds per square inch) listed on the sticker inside the driver’s-side door frame or in your owner’s manual. This number represents the ideal balance between safety, performance, and efficiency. Note that the maximum pressure printed on the tire’s sidewall is not the recommended inflation level for optimal vehicle performance.
Some drivers assume that inflating tires above the recommended PSI will improve MPG. While it’s true that higher pressure can reduce rolling resistance, it comes at a cost—less traction, uneven tire wear, and a bumpier ride. In extreme cases, overinflation can even increase the risk of tire failure. Sticking with the recommended pressure ensures you get the most out of every gallon in your Ford vehicle without compromising safety.
Built-In Ford Features That Help You Save Fuel
Ford makes it easier than ever to stay on top of your tire pressure and fuel efficiency with smart technologies built into most models, helping you conserve energy and improve gas mileage.
- Tire Pressure Monitoring System (TPMS): Found in nearly every new Ford, TPMS alerts you on the dash when your tire pressure drops below recommended levels. It’s a simple way to catch underinflation before it affects your gas mileage—or your safety.
- FordPass® App: With the FordPass App, you can check your vehicle’s tire pressure remotely and even schedule service at Moon Township Ford right from your smartphone.
- Eco Mode: Available on models like the Ford Escape and Ford Explorer, Eco Mode analyzes your driving habits and promotes more fuel-efficient behavior, helping you make the most of every mile.
Tire Pressure Tips to Maximize MPG
Once you understand how tire pressure affects gas mileage in your Ford vehicle, you can take small steps to ensure your tires are always at their best.
- Check tire pressures once a month—and always before long road trips.
- Use a digital tire gauge to get an accurate PSI reading.
- Adjust for the weather. Tire pressure tends to drop in colder temperatures, so check more frequently in the winter.
- Don’t rely on visual inspection alone. A tire can look fine and still be underinflated.
- Schedule regular service at Moon Township Ford for professional tire checks, rotations, and alignments.
- Drive at lower speeds to improve gas mileage. Optimal fuel economy is often achieved at lower speeds, which can also reduce wear on your tires.
- Maintain steady speeds for optimal fuel economy. Consistent speeds help achieve better gas mileage, especially during long trips with minimal traffic.
