The invention relates to the technical field of passenger tires, in particular to a tire tread structure for improving rolling resistance, application and a tire. The tire tread structure for improving the rolling resistance comprises a tire crown, a tire shoulder and a tire tread base part, the rubber thickness of the tire tread base part is h1, the rubber thickness of the tire crown is h2, and h1/h2 is equal to 0.10-0.35; the sectional area of the tire crown is S1, the sectional area of the tire shoulder is S2, and S1/S2 = 2-8.5; the 100% tensile modulus of the rubber material of the tread base part, the 100% tensile modulus of the rubber material of the tire crown and the 100% tensile modulus of the rubber material of the tire shoulder are 1.8-2.2 Mpa, 2.0-5.0 Mpa and 2.0-3.0 Mpa respectively. The tread structure can effectively reduce the rolling resistance, and meanwhile, the safety of the tire (the size of the tire material is not reduced) and the wet ground holding force (the hysteresis loss of the tread material is not reduced) are kept.
本发明涉及乘用轮胎技术领域,具体涉及一种改善滚动阻力的轮胎胎面结构、应用和轮胎。一种改善滚动阻力的轮胎胎面结构,该胎面结构包括胎冠、胎肩和胎面基部,所述胎面基部的胶厚度为h1、胎冠的胶厚度为h2,h1/h2=0.10‑0.35;胎冠截面积为S1,胎肩截面积为S2,S1/S2=2‑8.5;胎面基部、胎冠和胎肩的胶料的100%拉伸模量分别为:1.8‑2.2,2.0‑5.0,2.0‑3.0 Mpa。该胎面结构可以有效降低滚动阻力,同时,保持轮胎的安全性(轮胎材料体积不减小)和湿地抓地力(胎面材料滞后损失不降低)。
