PROBLEM TO BE SOLVED: To reduce rolling resistance by a method except a method using rubber having low rolling resistance and a method for forming the shape of a tread width direction cross section into a characteristic shape.SOLUTION: With a pneumatic tire 1 width SW and the pneumatic tire 1 outer diameter OD, the pneumatic tire 1 simultaneously satisfies SW≤175 mm and OD/SW≥3.6. When the pneumatic tire 1 inner diameter RD that is a diameter of a portion (an end portion of a bead portion) abutting on a wheel with the pneumatic tire 1 having the width SW and the outer diameter OD and fitted to the wheel, the pneumatic tire 1 simultaneously satisfies SW≤175 mm and OD/RD≤1.4. |
