WebSep 4, 2024 · A tire’s Coefficient of Rolling Resistance (Crr) refers to the power cost of the tire (and inner tube, if used). This is typically measured on a smooth metal drum or roller, and tells us how much energy it takes for the tire to deform and return to shape on the roller as it spins, which generates heat.
