Tire tester machine having a lubricator in a conveying direction

A tire testing machine for testing a tire, comprising:

• a conveyor belt, extending in a horizontal direction, for conveying the tire in a conveying direction;
• a lubricator, disposed at a position corresponding to a intermediate part of the conveyor belt in the conveying direction, for applying a lubricant to an inner circumferential surface of the tire;
• an adjusting arm for adjusting a position of the tire in a horizontal direction relative to the lubricator;
• and
• a free roller section, including a plurality of rollers arranged along the conveyor belt, for supporting the tire so that the tire is movable in a horizontal direction, the free roller section being movable in a vertical direction relative to the conveyor belt, between a lower position below the conveyor belt and an upper position above the conveyor belt, wherein
• the free roller section is configured such that the plurality of rollers include an endmost roller disposed downstream of the lubricator in the conveying direction and farthest from a predetermined reference position, the endmost roller being disposed such that a horizontal distance between the endmost roller and the reference position is equal to or greater than a radius of a largest one of a plurality of tires set in advance as objects of application of the lubricant, and
• the reference position is a position serving as a reference for a position of a center of the tire when the free roller section moves from the lower position to the upper position relative to the conveyor belt, the reference position being within an area of the lubricator in plan view.
