The invention discloses a detection device for automobile tires. The technical problems that existing automobile tires need to adopt various experiment instruments during detection, and the conditionsof different road surfaces cannot be simulated during tire driving detection can be solved. The detection device comprises a first base, a second base, cushioning pads and extrusion plates; one end of the first base is connected with the second base; one end of the first base and one end of the second base are connected with the cushioning pads with the circular-arc-shaped tops correspondingly; the middle ends in grooves are transversely connected with bolt rods, and the middles of the bolt rods are sleeved with limiting plates; the tops of mounting plates are connected with the uneven extrusion plates, and a sleeve is connected between two opposite screw rods at the ends of the first base and the second base; and a speed measuring instrument is mounted on one side of the second base. Thetires are detected through a method and the device, and the damage conditions of the tires travelling on the different road surfaces or same road surface at different speeds or at the same speed canbe accurately measured.
