A tire comprising a tread part, the tread part having a tread end To placed outside a vehicle and a tread end Ti placed inside the vehicle when mounted on the vehicle, and having one or more circumferential grooves extending continuously in a tire circumferential direction and two or more land parts (30, 40, 41) partitioned by the circumferential grooves between the tread end To and the tread end Ti, the land part having a plurality of lateral grooves (20, 21) extending in a tire width direction, characterised by the the- tread part comprising a rubber composition having a glass transition temperature (Tg) of -40°C to -15°C, the rubber composition comprising a rubber component having a total styrene amount of less than 20.0% by mass in the rubber component, wherein the rubber composition comprises a styrene-butadiene rubber, wherein a lateral groove area ratio of at least one land part of the land parts satisfies the following condition, and wherein a weight (kg) and the maximum load capacity (W L) (kg) of the tire satisfy the following condition: 10 % ≤ R ≤ 40 % WT / W L ≤ 0.015, wherein the maximum load capacity (W L) (kg) is determined by the following equations and when a tire cross-sectional width measured in a standardized state is defined as Lt (mm), a tire cross-sectional height is defined as Ht (mm), and a tire outer diameter is defined as Dt (mm), the above-described tire cross-sectional width Lt is a maximum width between outer surfaces of sidewalls excluding, if any, patterns or characters on the side surface of the tire in the standardized state, the above-described tire cross-sectional height Ht is a distance from the bottom surface of a bead part to the outermost surface of a tread, which is half a difference between the outer diameter of the tire and a nominal size of a rim, V = Dt / 2 2 − Dt / 2 − Ht 2 × π × Lt W L = 0.000011 × V + 100 wherein the standardized state is a state where the tire is rim-assembled on a standardized rim and a standardized internal pressure is filled, and no load is applied. the tread part having a tread end To placed outside a vehicle and a tread end Ti placed inside the vehicle when mounted on the vehicle, and having one or more circumferential grooves extending continuously in a tire circumferential direction and two or more land parts (30, 40, 41) partitioned by the circumferential grooves between the tread end To and the tread end Ti, the land part having a plurality of lateral grooves (20, 21) extending in a tire width direction, characterised by the the- tread part comprising a rubber composition having a glass transition temperature (Tg) of -40°C to -15°C, the rubber composition comprising a rubber component having a total styrene amount of less than 20.0% by mass in the rubber component, wherein the rubber composition comprises a styrene-butadiene rubber, wherein a lateral groove area ratio of at least one land part of the land parts satisfies the following condition, and wherein a weight (kg) and the maximum load capacity (W L) (kg) of the tire satisfy the following condition: 10 % ≤ R ≤ 40 % WT / W L ≤ 0.015, wherein the maximum load capacity (W L) (kg) is determined by the following equations and when a tire cross-sectional width measured in a standardized state is defined as Lt (mm), a tire cross-sectional height is defined as Ht (mm), and a tire outer diameter is defined as Dt (mm), the above-described tire cross-sectional width Lt is a maximum width between outer surfaces of sidewalls excluding, if any, patterns or characters on the side surface of the tire in the standardized state, the above-described tire cross-sectional height Ht is a distance from the bottom surface of a bead part to the outermost surface of a tread, which is half a difference between the outer diameter of the tire and a nominal size of a rim, V = Dt / 2 2 − Dt / 2 − Ht 2 × π × Lt W L = 0.000011 × V + 100 wherein the standardized state is a state where the tire is rim-assembled on a standardized rim and a standardized internal pressure is filled, and no load is applied. V = Dt / 2 2 − Dt / 2 − Ht 2 × π × Lt W L = 0.000011 × V + 100
