Abstract
A pneumatic tire includes a tread portion, sidewall portions, bead portions, and has at least one carcass layer disposed between the pair of bead portions. The ratio SW/OD between the total tire width SW and the tire external diameter OD satisfies the relationship SW/OD≤0.3. A first region A is defined between a pair of first boundary lines (L1, L1), second regions B are defined between a first boundary line (L1) and a second boundary line (L2), and third regions C are defined on the bead toe side of the second boundary lines (L2). Defining SA, SB, and SC as the cross-sectional area (mm2) of the first region A to the third region C, and defining the peripheral lengths (mm) of the first region A to third region C along the tire inner surface as a, b, and c, respectively, the relationship 7.5≤SA/a≤11.5 is satisfied.
