Abstract: The present technology pertains to a pneumatic tire (1) comprising: a pair of bead portions (2); sidewall portions (3) connected to the pair of bead portions; and a tread portion (10) connected to the sidewall portions. A ratio between a total width (SW) and an outer diameter (OD) of the pneumatic tire satisfies the relationship SW/OD≦0.3. Moreover, if the length along a tread profile (12) from a first side second reference point (Q1) to a second side second reference point (Q2) is the developed tread width (TDW), and an angle formed between a straight line that connects the second reference points and the profile center (cc), and a straight line parallel to the tire width direction is an amount of depression (θ), the following relationships are satisfied: 0.8≦TDW/SW

Abstract: A pneumatic tire unit comprises a front tire to be mounted on a leading side of a vehicle, and a rear tire to be mounted on a trailing side of the vehicle. A plurality of recesses is provided in at least one tire side portion of the front tire, and a plurality of protrusions is provided on at least one tire side portion of the rear tire. A negative pressure region that can be generated at a back surface side of the vehicle is reduced and, therefore, air resistance of the vehicle is reduced and fuel economy is enhanced.
Abstract translation: 一种充气轮胎单元包括要安装在车辆前方的前轮胎和将被安装在车辆后方的后轮胎。 在前轮胎的至少一个轮胎侧部设置有多个凹部，在后轮胎的至少一个轮胎侧部设置有多个突起。 可以减轻在车辆的后表面侧产生的负压区域，因此，车辆的空气阻力降低，燃料经济性提高。

Abstract: A pneumatic tire includes circumferential main grooves extending in the tire circumferential direction and a land portion defined by the circumferential main grooves. The land portion includes a through lug groove that passes through the land portion in the tire lateral direction and includes first and second chamfered portions formed on left and right edge portions of the through lug groove. The first chamfered portion opens at one end to one of the edge portions of the land portion and terminates at the other end at a central portion in the groove length direction of the through lug groove. The second chamfered portion opens at one end portion to one of the edge portions of the land portion and terminates at the other end portion at a central portion in the groove length direction of the through lug groove.

Abstract: A ratio between the total width (SW) and outer diameter (OD) of a pneumatic tire, which has an asymmetrical pattern formed by grooves formed on a tread part, satisfies SW/OD≤0.3. Given a ground contact width (CW) in a ground contact region in the tread part, a groove area ratio (GR), and a groove area ratio (GRi) of a tire inner side region (Ai), which spans from a tire equator line (CL) to the vehicle side in the ground contact region, and a groove area ratio (GRo) of a tire outer side region (Ao), which spans from the tire equator line to the opposite side of the vehicle side in the ground contact region, the ground contact region is formed to satisfy 0.75≤CW/SW≤0.9, 10≤GR≤25%, and GRi
