To measure the rolling resistance of a tire, use a drum tester. This device has a rotating drum made of concrete or metal. The drum rotates at a constant speed while the tire rolls against it. This setup allows for precise measurement of the tire’s rolling resistance.
Tire manufacturers often use these tests to compare tire performance. They also help consumers make informed choices based on energy efficiency. Lower rolling resistance typically leads to better fuel economy and reduced environmental impact.
Understanding these tests is vital for vehicle performance. Tire rolling resistance plays a critical role not only in fuel consumption but also in overall vehicle dynamics.
Next, we will explore various factors influencing rolling resistance, including tire construction, materials, and tread design. These elements significantly affect tire efficiency and performance on different surfaces.
