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.
Claims13
A solid tire, comprising:
- a tread rubber layer on a road contact surface side of the solid tire, the road contact surface side being configured to contact a road;
- and
- a base rubber layer on a rim side of the solid tire, the rim side being configured to contact a rim when the solid tire is mounted on a rim;
- the base rubber layer having JIS-A hardness of 80 or higher, and
- an RFID tag being embedded in the base rubber layer;
- wherein
- a distance between the RFID tag and a side surface of the base rubber layer ranges from 0.5 mm to 10.0 mm,
- the RFID tag is disposed at a position deviating from a rim slippage region defined within a range of −15% to +15% of a rim flange height with an apex of a rim flange as a center, and
- the RFID tag is disposed radially inward of the rim slippage region.
