Title:
TIRE
Document Type and Number:
WIPO Patent Application WO/2023/105813
Kind Code:
A1
Abstract:
A tire 1 comprises side rubber 8, a bead filler 4b, a carcass 5, and a communication device 10. The communication device has an RF tag 10e and a tag-covering rubber section 10f that covers the RF tag, and the communication device is disposed between the side rubber and the bead filler. The 100% modulus M100 of the side rubber is less than the 100% modulus M100 of the tag-covering rubber section, the 100% modulus M100 of the tag-covering rubber section is less than the 100% modulus M100 of a contact bead filler section that is a part of the bead filler and is in contact with the communication device. The loss tangent tanδ of the side rubber is greater than the loss tangent tanδ of the contact bead filler section, and the thermal conductivity of a carcass cord is higher than the thermal conductivities of the contact bead filler section and the tag-covering rubber section.
