How do tires affect fuel consumption?

Premium summer and winter tires consume less fuel thanks to their lower rolling resistance. Driving economically and maintaining tires can also help with fuel savings. On average, tires are used to drive 20,000–30,000 miles so the saving may amount to almost 500 USD. This is enough to buy a complete set of tires. It is not a good idea to use lower tire pressures as fuller tires reduce the rolling resistance by up to ten percent – and when a tire rolls more easily, less fuel is used. In addition to having good, well maintained tires, fuel consumption can be significantly reduced by driving economically. Easing off the gas can save on fuel and car maintenance. Avoid driving recklessly, braking and accelerating sharply, and driving in low gear.
