  "textContent": "Provided is a tire comprising a tread part, the tread part comprising at least one rubber layer of a rubber composition comprising a rubber component and a thermoplastic elastomer, wherein a ratio (WT/WL) of a tire weight WT (kg) to a maximum load capacity WL (kg) of the tire is 0.0180 or less, wherein, in a dynamic viscoelasticity test (temperature-dependent measurement at 10Hz) in accordance with JIS K 6394, the thermoplastic elastomer exhibits a tan δ peak value in a range of -20°C to 20°C, and the peak value is 1.00 or more. While being lightweight, the tire can improve in ride comfort and particularly suppress deterioration of ride comfort due to abrasion.",
