▎ 摘　　要

NOVELTY - Vehicle tire comprises a piezoelectric device which comprises a layer of a piezoelectric polymer having first and second opposing sides, and a first and a second layer of an electrically conductive rubber composition provided adjacent to the first and second opposing sides of the layer of piezoelectric polymer. USE - Used as vehicle tire. ADVANTAGE - The vehicle tire utilizes the electrically conductive rubber composition which has a volume resistivity of less than or equal to 107 Omega -cm at a temperature of 20 degrees C (determined from dynamic mechanical analysis (DMA) measurements according to ISO 6721-12, frequency 1-100 Hz, 0.25 MPa dynamic stress and 0.35 MPa static stress), or 103 to 107 Omega -cm at a temperature of 90 degrees C (determined from DMA measurements according to ISO 6721-12, frequency 100 Hz, 0.25 MPa dynamic stress and 0.35 MPa static stress).
