A tire comprising a tread part, wherein a ratio (G/W L) of a tire weight G (kg) with respect to a maximum load capability W L (kg) of the tire is 0.0131 or less, wherein the tire weight G (kg) indicates the weight of a standalone tire unit not including the weight of the rim, and in a case that a noise damping material, a sealant, a sensor, and the like are mounted to a tire inner cavity part, the tire weight G is a value including the weights thereof; in a case of a tire having a size specified in the JATMA standard, the maximum load capability W L (kg) indicates a load capability value (kg) when a maximum air pressure (kPa) is filled, which maximum air pressure (kPa) corresponds to a tire having, under the use conditions defined in the JATMA standard, a load index thereof; and in a case of a tire having a size not specified in the JATMA standard, it is to be a value calculated using the following Equations and: V = Dt / 2 2 − Dt / 2 − Ht 2 × π × Wt, W L = 0.000011 × V + 100, where Wt (mm) is a tire cross-sectional width indicating a maximum width between side wall outer surfaces in a normal state, with any patterns or letters on a tire side surface being excluded, Ht (mm) is a tire cross-sectional height indicating the distance from a bead part bottom surface to a tread uppermost surface and being 1/2 the difference between an outer diameter and a port rim diameter of the tire, and Dt (mm) is the tire outer diameter when the tire is filled with air at 250 kPa; wherein the tread comprises at least one rubber layer (6,7) composed of a rubber composition comprising a rubber component and a reinforcing filler, wherein, under conditions of an initial strain of 5%, a dynamic strain of 1%, and a frequency of 10 Hz, tan δ at 30°C (30°C tan δ) of the rubber composition is over 0.15, and complex modulus at 30°C (E* 30) of the rubber composition is less than 8.0 MPa, and wherein a ratio (30°C tan δ/G) of the 30°C tan δ with respect to the tire weight G is 0.016 or more. wherein a ratio (G/W L) of a tire weight G (kg) with respect to a maximum load capability W L (kg) of the tire is 0.0131 or less, wherein the tire weight G (kg) indicates the weight of a standalone tire unit not including the weight of the rim, and in a case that a noise damping material, a sealant, a sensor, and the like are mounted to a tire inner cavity part, the tire weight G is a value including the weights thereof;
