An abnormality monitoring system includes gas sensors provided in the cavity or the vicinity of a tire provided in a vehicle, a determination unit that determines the presence of an abnormality in the tire on the basis of the detection results of the gas sensors, and an output unit that outputs data based on the determination result of the determination unit. The gas sensors detect a volatile substance when abnormal heat build-up occurs in the tire. The volatile substance is a substance derived from an additive added when a tire is manufactured.

Abnormality monitoring system

An RFID module comprising a transponder covered with a 0.2 to 2 mm thick rubber sheet containing 100 parts by weight of a diene-based rubber, less than 30 parts by weight of carbon black and 5 to 55 parts by weight of silica, having a relative permittivity of 7 or less and having a dynamic modulus of elasticity (E') of 2 to 12 MPa, which can extend a communication distance with a required installation location and is superior in the durability at the time of being embedded in the tire.
