How To Modify Your Truck Without Destroying Your Fuel Economy

June 16, 2022

Modifying your truck in 2022 may not be really high up on your list of priorities. With the rising cost of fuel, parts, and shipping delays it may not seem like the right time. After all, who wants to ruin their fuel economy and end up paying more at the pump? It doesn't have to be that way though, you can still modify your truck without killing your fuel economy and we’re going to tell you how.

Choosing a smaller wheel size can go a long way in saving fuel. A 17”, 18”, or 20x9 wheel will be lighter and will require less force to spin than a 20x10 or larger wheel. The weight savings will also benefit the performance of your truck, lowering acceleration and deceleration times. For example, a 20x10 Method MR305 wheel weighs 37 pounds. If you opt for a 17x8.5 MR305 you will save 9 pounds per wheel, plus the mass of the wheel being closer to your truck's hub also helps improve fuel economy.


If preserving fuel economy is your main concern you will want to stay close to your factory size for tires as large tires take more energy to spin and can lead to a drop in MPG. The tread pattern also plays a big part in how efficient your truck is, some manufacturers even offer low rolling resistance tires so you can make your build as fuel-efficient as possible. Some examples of this are the Michelin LTX A/T 2 and the General Grabber HTS.


In summary, stick to smaller wheel sizes and less aggressive tires when modifying your truck to conserve fuel while modifying your truck.
