A diagnostic testing device for diagnosing and testing chassis, mechanical, tire and tire tread problems in vehicles which simulates normal operating angles and normal vehicle weight conditions with the wheels of the vehicle being cycled and steered at a full range of vehicle speeds. The diagnostic testing device includes a support having a horizontal upper surface, a platform movably coupled to the upper surface of the support so as to allow the platform to glide horizontally in any direction, and a pair of support rollers rotatably connected to the platform so as to provide rolling surfaces to contact the tire tread and which allow a tire to cycle and be steered when placed upon said rollers.
