…replacement tires with lower rolling resistance to further improve fuel economy. While our last complete test has a great deal of information to help distinguish the different models from one another, the question remains: How much difference will I see once a low rolling resistance tire is…
…2010 test season - just another example of how we provide the most comprehensive information in the industry. While there is no industry standard established, many manufacturers have turned their attention to the issue of fuel economy. Typically, you can identify a low rolling resistance tire by its…
…in low rolling resistance tires. Last summer, Tire Rack tested three eco-focused tires that advertise better fuel economy and all-season capability: the Bridgestone Ecopia EP422, Continental ProContact with EcoPlus Technology, and Goodyear Assurance Fuel Max against a typical passenger car tire, the…
…tires make, we conduct straight-line braking tests to accurately measure panic stopping distances. We stabilize the speed at 50 miles per hour and hit the brakes hard enough to engage the anti-lock braking system and bring the vehicle to a complete stop. We run multiple stops on each tire and use a…
…trade-offs when it comes to low rolling resistance tires. My first experience driving a vehicle with the new crop of low rolling resistance tires came last year while visiting the Continental Tire Proving Grounds in Uvalde, Texas. Among the driving exercises was a braking test: we had to accelerate…
…The lower the tire rolling resistance, the less energy required to drive the vehicle. For gasoline-powered vehicles, lower rolling resistance also results in a reduction of CO2 gasses emitted in their exhaust. The difference in energy consumption between new A-rated and G-rated tires could be as…
…fuel economy over the tire’s lifetime. Goodyear’s Fuel Max Technology helps retain longer tread life, while providing 27 percent less rolling resistance, which equates to approximately 2,600 miles worth of fuel over the life of a set compared to standard tires. For more information on…
…keep a tire rolling, the car becomes less expensive to run long term and reduces its impact on the environment by reducing carbon emissions.

…radial tire has a whopping 20% increase in rolling resistance over a low rolling resistance Original Equipment standard passenger radial. To calculate the potential change in mpg resulting from using the high performance tires in place of the Original Equipment tires, we would multiply the tire's…
…sized tires to one another. Tire Rolling Resistance Coefficient is calculated by dividing the measured rolling resistance force by the tire size's prescribed load during the test. Comparing Rolling Resistance Coefficients only allows comparing tires within a single size. Tire Rolling Resistance…
…to more effectively retain tire inflation pressure while it reduces tire weight and rolling resistance. We were able to include the Yokohama in a tire test we conducted last fall against other low rolling resistance tires, see the test results here! Currently, the tire is limited to four sizes aimed…
…to a Friend Tire Tech: Tire Rolling Resistance Part 3: Changes to Expect When Switching from Worn-Out to New Tires New, Full-Treaded Tires Generate More Rolling Resistance Than Shallow-Treaded, Worn Tires Tire rolling resistance gradually drops by about 20% during the life of a tire as the tread…
