<P>PROBLEM TO BE SOLVED: To provide a pneumatic tire in which information can be read and written even in a state in which a plane, to which a RFID (Radio Frequency Identification) tag of a tire is attached, is grounded to the surface of land. <P>SOLUTION: An antenna of a RFID tag 1 strides across a ground plane during normal weight and normal internal pressure from an axis direction center of the back surface of a tread part 3, and is extended, by 2 to 3 cm, to out of a grounding end from a position of a grounding end (tread end) 3a of a tire. When the plane to which the RFID tag of the tire is attached is grounded to the surface of land, a RFID reader/writer 7 is made to approach to a gap existing, between the tire tread part 3 containing the antenna and the surface of land, from a tire side plane side, and information of the RFID tag is read and written. <P>COPYRIGHT: (C)2012,JPO&INPIT |
