<p>In the present invention, a pneumatic tire uses bead wires on which a coumarone resin film is formed. The coumarone resin constituting the coumarone resin film has a melting point of 75°C or greater and equal to or less than the heating temperature (°C), and the amount of coumarone resin coated over the bead wires is 0.04 to 0.08 g/wire kg/wire mm. The heating temperature is the heating temperature of the bead wires when the bead cores are manufactured, and is preferably 90 to 110°C. The melting point of the coumarone resin is preferably 75°C or more and equal to or less than -5°C less than the heating temperature (°C).</p> |
