The test drum has an outer radial surface and a plurality of sectioned plates having outer radial test surfaces, wherein the plurality of sectioned plates mount on the outer radial surface of the test drum. The tire testing apparatus further includes at least one tire station having a selected tire with a tread, wherein the tread of the selected tire presses against the outer radial test surface of the plurality of sectional plates, and wherein the at least one tire station applies a force against the tread of the selected tire. Further, a tire testing method includes providing a selected tire having a circumferential tread and moving the selected tire against a rotating test drum having a plurality of sectional plates having a test surface. Further, the method includes maintaining contact between the selected tire and the plurality of sectional plates for a selected period of time, moving the selected tire away from the test drum, and evaluating the tread for wear.
