  "textContent": "A bead portion (4) of a pneumatic tire (1) includes a vertical rising surface portion (Sw1) which is connected to a bead base surface (Sb) through an arc bead heel surface (Sh), and a straight or convex arc flange receiving surface portion (Sw2) which is diagonally extending from the rising surface portion (Sw1) radially outward and axially outward of the tire. In a normal internal pressure in which no load is applied, the flange receiving surface portion (Sw2) is not in contact with a flange surface (Rf), and in a load state in which 50% or more of normal load is applied, the flange receiving surface portion (Sw2) comes into contact with the flange surface (Rf).",
