What is Rolling Resistance?

Do bigger wheels affect MPG? Yes. So, why do tires affect MPG? When you drive through Stoughton, “rolling resistance” is the force that slows down your tires. Rolling resistance refers to the resistance between the surface of the road and your wheel – so more resistance leads to poorer fuel economy. Many factors affect your rolling resistance: air drag, road quality, etc. But, bigger tires will always have greater rolling resistance than a smaller set. You can even look into low rolling resistance tires with thinner sidewalls, lower weight, and shallower tread depth for a fuel economy boost.

How Much Does Tire Weight Affect MPG?

Do bigger wheels affect MPG and how much does tire weight affect MPG? Let’s break it down:

  • A smaller object is easier to move than a larger one, so it makes sense that a larger wheel is harder to move than a smaller one.
  • Because smaller wheels move more easily, they need less power and fuel to propel forward. And in West Bridgewater stop-and-go traffic, smaller tires will also handle the wear and tear better.
  • What advantages do larger tires have? Larger tires will cover a larger distance once they are in motion. This is a huge advantage if you do mostly highway driving, rather than city driving.
