Abstract
In a solid tire including a tread rubber layer on a road contact surface side and a base rubber layer on a rim side, the base rubber layer has JIS-A hardness of 80 or higher, and an RFID tag is embedded in the base rubber layer. When forming an unvulcanized tire by winding a rubber sheet into multiple layers, the RFID tag is inserted between layers of the rubber sheet in the middle of the winding into multiple layers, or the RFID tag and a coating layer are overlaid and attached on a side surface of the unvulcanized tire, and then the unvulcanized tire including the RFID tag is vulcanized in a mold.
