Provided are a tire tangential load measuring device capable of directly measuring a tangential load of a tire and a tire rolling resistance evaluating device capable of evaluating a rolling resistance of a tire using the tire tangential load measuring device, without using a large-sized device. A tire tangential load measuring device (10) includes two or more load rolls (44A, 44B) smaller in diameter than that of the tire and arranged side by side, an air cylinder (13) as a moving mechanism capable of pressing the two or more load rolls (44A, 44B) against the rotating tire with a predetermined load fz, and a strain gauge (51) as a tangential load sensor for measuring the tangential load fx of the tire in a rotating state while the surfaces of the two or more load rolls (44A, 44B) are pressed against the tread surface of the tire with the predetermined load fz. The tire rolling resistance evaluating device uses the tangential load measuring device (10).
