Beginning in 2010, Tire Rack tests will measure the fuel consumption of our regular test cars when equipped with a variety of tires. This portion of pir tests will highlight how a tire’s rolling resistance influences vehicle efficiency, as well as the role vehicle selection plays in determining annual fuel costs.
We have added a comparison to the tire test reports that projects the number of gallons each vehicle/tire combination would require for driving 15,000 miles (typical annual mileage traveled in the U.S.).
In addition to testing performance, touring and passenger tires, Tire Rack will compare eco-oriented car and light truck tires that promise greater fuel-efficiency. We will compare two new low rolling resistance tire lines to two similar tire lines from last year’s test. The results of these tests will be made available on our website in the near future.
Choosing more fuel-efficient tires can influence how much fuel a specific vehicle consumes. However, differences between tires don’t have as much influence on a driver’s annual fuel costs as differences in the efficiency of the vehicles they’ve selected.
