PROBLEM TO BE SOLVED: To reduce the rolling resistance by a method other than a method which uses rubber with low rolling resistance and other than a method which makes the shape of a cross section in a tread width direction a distinctive shape.SOLUTION: A pneumatic tire 1 satisfies SW≤175 mm and OD/SW≥3.6 simultaneously, where SW is the width of the pneumatic tire 1 and OD is the outer diameter of the pneumatic tire 1. In addition, the pneumatic tire 1 satisfies SW≤175 mm and OD/RD≤1.4 simultaneously, where SW is the width, OD is the outer diameter, and RD is the inner diameter of the pneumatic tire 1, which is the diameter of a portion (an end portion of a bead portion) in contact with a wheel in a state where the pneumatic tire 1 is fitted to the wheel. |
