Hereinafter, specific embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 2 is a cross-sectional view showing a RFID tag mounted inside an apex as a first embodiment of a tire equipped with an RFID tag according to the present invention.

The tire 10 equipped with the RFID tag includes an outer tread 12, a cap ply 14, a belt 16, an inner liner 18, an apex 30, a bead 32, and an RFID tag 35. It is composed.

The outer tread 12 is a thick layer of rubber on the road surface contact outside the tire. The cap ply 14 is a special coded paper located inside the outer tread 12 to improve performance while driving and prevent the belt from being dislodged. The belt 16 is located inside the outer tread 12 and the cap ply 14 and is an iron core layer that mitigates external shocks.

The inner liner 18 is located on the innermost side of the tire and is made of rubber. Apex 30 is located on the side of the tire cross section to minimize the dispersion of beads, to mitigate external shocks, and is made of a long triangle type rubber material. And the bead 32 serves to fix the rim (Rim) to the tire by a bundle of iron cores of the square or hexagonal form coated with rubber on the iron core. The RFIF tag 35 is mounted inside the apex 30 and contains unique information such as a tire manufacturing date, a manufacturer, a product number, and the like.

Since the apex 30 is made of rubber, when the RFID tag 35 is mounted therein, the RFID tag 35 is completely covered with rubber, thereby eliminating the problem of detachment of the tag due to high speed rotation.
