<P>PROBLEM TO BE SOLVED: To provide a method and a device for measuring dynamic landing shape of a tire capable of measuring easily dynamic landing shape of a tire on a desired place. <P>SOLUTION: In this dynamic landing shape of a tire measuring method, a laser scan type two-dimensional displacement gage 3 mounted on a rim R oppositely to a tread part T3 in a hollow part T2 of a pneumatic tire T is used, and the landing pneumatic tire T is rotated, and the distance to a tire inner surface T1 of the tread part T3 is detected at every time when the pneumatic tire T rotates a prescribed timed on a plurality of positions in the tire width direction by the displacement gage 3 rotated and moved in the tire circumferential direction following rotation of the pneumatic tire T. A tire inner surface landing shape is operated and determined from data of the detected distance. <P>COPYRIGHT: (C)2007,JPO&INPIT |
