Abstract
A pneumatic tire has a ratio SW/OD between the total tire width SW and the tire external diameter OD satisfying SW/OD≤0.3. A first region A is defined between a pair of first boundary lines, second regions B are defined between a first boundary line and a second boundary line, and third regions C are defined on the bead toe side of the second boundary lines. Defining SA, SB, and SC as the cross-sectional area (mm) of the first region A to the third region C, and defining the peripheral length (mm) of the first region A to third region C along the tire inner surface as a, b, and c, SA/a and SB/b satisfy 7.5≤SA/a≤11.5 and 2.0≤SB/b≤6.0, and the ratio TDW/SW between the developed tread width TDW and the total tire width SW satisfies 0.7≤TDW/SW≤0.95.
