Low Rolling Resistance Tires

Tire Rack, tire retail partners and several manufacturers recently teamed up with the White House and Department of Transportation (DOT) to introduce a new tire safety and efficiency program, TireWise. As part of the program, the DOT will finalize a rule to establish a tire fuel efficiency program so consumers can identify the most energy-efficient tires.

The best modification anyone can make to a vehicle is to change the tires. This change can help increase your fuel economy by switching to a tire with a low rolling resistance designation.

A tire's ability to easily roll affects your fuel economy. Tread design, tread compound and tire weight also play a factor. Currently, there isn't a standard for measuring a tire's rolling resistance. A tire's eco-friendly designation is given by the tire manufacturer with many different intentions. This can be anything from the way the tire is manufactured, to its ability to roll, to the materials used when building the tire.  

When changing from a worn out tire to a new, low rolling resistant tire, you will likely not instantly increase your fuel economy. This is due to the change in diameter of the tire. Once a tire becomes worn in, you will see the difference the tire can make. Some of the top low rolling resistance tires to consider are the:
