A tire having a tread part in which a mounting direction to a vehicle is designated, wherein the tread part has an inner tread rubber layer forming an end side inside the vehicle when the tire is mounted to the vehicle and an outer tread rubber layer forming an end side outside the vehicle when the tire is mounted to the vehicle, wherein a ratio of a distance D from a grounding end outside the vehicle to an interface between the inner tread rubber layer and the outer tread rubber layer with respect to a distance W L between a grounding end inside the vehicle and the grounding end outside the vehicle (D/W L) is 0.50 or more, characterised in that an average value of a loss tangent tan δ at 0°C to 50°C of the inner tread rubber layer, measured under a condition of a frequency of 10 Hz, an initial strain of 1%, and an amplitude of ± 0.1%, is defined as tan δA in, tan δA in is 0.30 or less, and wherein an average value of a loss tangent tan δ at 0°C to 50°C of the outer tread rubber layer, measured under a condition of a frequency of 10 Hz, an initial strain of 1%, and an amplitude of ± 0.1%, is defined as tan δA out, tan δA out is 0.40 or more, wherein tan δA out and D/W L satisfy the following inequality: tan δA out × D / W L ≥ 0.30, wherein the "tan δA" is obtained by measuring a tan δ at each temperature from 0°C to 50°C in 5°C increments under a condition of a frequency of 10 Hz, an initial strain of 1%, and an amplitude of ± 0.1%, and calculating an average value of numerical values obtained, wherein a sample for tan δA measurement is a vulcanized rubber composition with 20 mm in length × 4 mm in width × 1 mm in thickness, when it is produced by being cut out from a tire, it is cut out from a tread part of the tire so that a tire circumferential direction becomes a long side and a tire radial direction becomes a thickness direction. wherein the tread part has an inner tread rubber layer forming an end side inside the vehicle when the tire is mounted to the vehicle and an outer tread rubber layer forming an end side outside the vehicle when the tire is mounted to the vehicle, wherein a ratio of a distance D from a grounding end outside the vehicle to an interface between the inner tread rubber layer and the outer tread rubber layer with respect to a distance W L between a grounding end inside the vehicle and the grounding end outside the vehicle (D/W L) is 0.50 or more, characterised in that an average value of a loss tangent tan δ at 0°C to 50°C of the inner tread rubber layer, measured under a condition of a frequency of 10 Hz, an initial strain of 1%, and an amplitude of ± 0.1%, is defined as tan δA in, tan δA in is 0.30 or less, and wherein an average value of a loss tangent tan δ at 0°C to 50°C of the outer tread rubber layer, measured under a condition of a frequency of 10 Hz, an initial strain of 1%, and an amplitude of ± 0.1%, is defined as tan δA out, tan δA out is 0.40 or more, wherein tan δA out and D/W L satisfy the following inequality: tan δA out × D / W L ≥ 0.30, wherein the "tan δA" is obtained by measuring a tan δ at each temperature from 0°C to 50°C in 5°C increments under a condition of a frequency of 10 Hz, an initial strain of 1%, and an amplitude of ± 0.1%, and calculating an average value of numerical values obtained, wherein a sample for tan δA measurement is a vulcanized rubber composition with 20 mm in length × 4 mm in width × 1 mm in thickness, when it is produced by being cut out from a tire, it is cut out from a tread part of the tire so that a tire circumferential direction becomes a long side and a tire radial direction becomes a thickness direction.
