The invention relates to the field of tires, in particular to a tire capable of reducing air resistance, the tire comprises a tread, a sidewall, a tire body and a bead toe, a groove is formed in the outer surface of the sidewall, a plurality of strip-shaped protrusions which are arranged in order and have a certain height are arranged at the bottom of the groove, the section of each strip-shaped protrusion is a boss, the bottom surface of each boss is located at the bottom of the groove, and the bottom surface of each boss is located at the bottom of the groove. The boss integrally extends upwards, and the average height h2 of the boss is 0.2-1 mm; the average width L2 of the bosses ranges from 0.05 mm to 0.08 mm. The average distance L1 between the bosses ranges from 0.05 mm to 0.3 mm. And an angle theta 2 formed between the side wall of the boss and a plane vertical to the tire body is 5-30 degrees. The tire has the advantages that the grooves are formed in the tire side wall, the strip-shaped protrusions are arranged in the grooves, and when air flows through the grooves and fluctuates back and forth between the protrusions, a small turbulent flow or air disturbance is generated, and air resistance is reduced in the process of separation, separation and reattachment of the air.

    本发明涉及轮胎领域,尤其是一种减小空气阻力的轮胎,该轮胎包括胎面、胎侧、胎体和胎趾,在胎侧的外表面上设置有凹槽,凹槽的槽底设置有若干条有序排列并具有一定高度的条状凸起,条状凸起的剖面形状为凸台,凸台的底面位于槽底,凸台整体向上延伸,凸台的平均高度h2为0.2‑1mm;凸台的平均宽度L2为0.05‑0.08mm;凸台的平均间距L1为0.05‑0.3mm;凸台的侧壁与垂直于胎体的平面之间形成的角度θ2为5‑30°。本发明的优点是在胎侧上设置凹槽,凹槽内设置条状凸起,当空气流过凹槽,在凸起之间来回起伏,产生一小块湍流或空气扰动,空气经过分离,分离、再附着的过程中就减小了风阻。
