Do Bigger Wheels Affect MPG?

Do bigger tires affect mpg? How do they differ from a smaller set? Bigger tires are generally less efficient, and to understand why, you need to learn about “rolling resistance”. Rolling resistance is the force that slows down your tires as you navigate Sumner. Larger tires have more rolling resistance, which means more force slowing them down. This leads to poorer fuel economy when compared to a smaller set of tires. If you’ve got your heart set on a set of larger tires, consider low-resistance tires with thinner sidewalls, lower weight, and shallower treads to gain back some fuel efficiency.

How Much Does Tire Weight Affect MPG?

How much does tire weight affect mpg? The more weight your car is carrying, the less efficient it will be. But, there’s a little more to explore:

  • Smaller objects take less energy to move, while bigger objects take more energy to move. That means your engine needs to burn more fuel, or energy, to move larger tires.
  • Because smaller tires require less engine power to start moving, they are a great option for the stop-and-go traffic of a Puyallup city commute.
  • Larger tires take more engine power to start moving, but once in motion, they cover more distance. That means larger tires are actually a great choice for highway driving.
