  "textContent": "Provided is a sidewall structure of a tire, belonging to the technical field of sidewall structures. The sidewall structure of the tire includes a tire, a side surface of the tire is designed with multiple knurling lines which are formed on a sidewall of the tire by a knurling engraving process. The knurling lines are composed of sparse knurling lines and dense knurling lines which are alternately arranged on the sidewall of the tire. The knurling lines are composed of radial protrusions distributed in an array, and the knurling lines and the tire are integrally formed. The sparse knurling lines and the dense knurling lines are composed of a plurality of knurling lines which are arranged in parallel to form non-closed polygonal patterns, respectively, and the sparse knurling lines and the dense knurling lines are connected and combined to form a new polygonal pattern on the sidewall of the tire.",
