A tire testing assembly adapted to provide precise displacements and simulate slow rate conditions, the tire testing assembly including: a support structure adapted to be coupled to a tire under test; a ground plane adapted to contact the tire under test and simulate a ground or road surface; and a lateral translation mechanism movably coupled between the support structure and the tire under test and adapted to translate the tire under test laterally relative to the ground plane. The tire testing assembly also includes a steering frame pivotably coupled between the support structure and the tire under test and adapted to pivot the tire under test about a steer axis of rotation relative to the ground plane. The tire testing assembly further includes a longitudinal translation mechanism movably coupled between the support structure and the tire under test and adapted to translate the tire under test longitudinally relative to the ground plane.
