The present invention relates to an apparatus for testing characteristics of a tire on various special load surfaces indoors, and more specifically, to an indoor testing apparatus which is capable of providing various special load surfaces for testing characteristics of a tire under high speed conditions. The indoor testing apparatus, which gives a load, a slip angle, and a camber angle to a tire (1) to be tested, is equipped with a spindle driving motor (3) having a load cell, and runs the tire (1) at a specific or higher speed to measure dynamic characteristics, comprises: a flat base (5) which forms a load surface that the tire (1) contacts; a main frame (6) which includes a spindle driving motor (3) controlling traveling, braking, a slip angle, and a camber angle after mounting the tire (1) thereon; a transfer roller guide (7) which transfers and guides the main frame (6) at a test speed; an accelerating free roller (8) which freely rolling the tire (1) to be accelerated to the test speed; a start device (9) which pushes the main frame (6), on which the tire (1) is mounted, to be accelerated and start off from the load surface (4); a decelerating device (11) which includes a decelerating free roller (10) which is capable of decelerating and stopping the main frame; and a shock absorbing frame (12) which for absorbing shocks to stop the main frame when the main frame (6) is decelerated.
