How many mpg do you lose with bigger tires?
Changing the diameter of a vehicle’s tire can drastically affect every aspect of its performance, from acceleration, to braking, to fuel economy. From one extreme to the next, a vehicle can gain or loose as much as 25 percent of its fuel economy, just by changing tire diameter.
What causes a sudden drop in gas mileage?
Such a drastic drop in mileage is often associated with a bad 02 sensor. I’ve had them go bad and cause a 25-35% drop in fuel efficiency. Did you have anything done to the car just before the mileage dropped? A drop like this has to have an assignable cause, and it often traces back to a maintenance that was just performed.
What does it mean when Your MPG drops 20%?
BTW, there is a code if the ECT (engine coolant temp) does not come up withing a certain time frame. You could also have a fuel leak. My 2010 FIT dropped 20% immediately upon moving to a much colder climate. I checked tire pressure and changed air filter, changed gas stations. Still off by 20% ( 10 miles per gallon).
What can I do to improve my gas mileage?
Eliminate excess weight by emptying your trunk, backseats or cargo areas. Tires can drastically affect your vehicle’s mpg. Check your tires regularly and keep their pressure at the manufacturer’s recommended pounds per square inch (psi) for optimum gas mileage. The amount is usually printed right on the tires themselves.
Why did my mpg drop on my 2010 fit?
My 2010 FIT dropped 20% immediately upon moving to a much colder climate. I checked tire pressure and changed air filter, changed gas stations. Still off by 20% ( 10 miles per gallon). Is it just the cold environment? Car is parked in a garage when not driven

Do you get worse gas mileage with 16 inch rims?
If you replace your 16 inch steel rims with 20inch steel rims you will get worse gas mileage. A wheel is like a donugut, most of the wight is far from the center of the wheel. If the wheel weighs 20 lbs and you move that weight 4 inches further from the center of the wheel it will take more energy to move it and you will get worse gas mileage.
