A pneumatic tyre comprising: a tread portion; a pair of sidewall portions; a pair of bead portions; a carcass extending between the pair of bead portions through the tread portion and the pair of sidewall portions; a belt layer disposed outwardly in a tyre radial direction of the carcass, the belt layer comprising at least two belt plies (7A, 7B); a band layer disposed outwardly in the tyre radial direction of the belt layer; and a pair of belt-edge rubbers disposed between the belt layer and the band layer to cover axially outer edges of the belt layer, wherein the band layer comprises at least one full band and a pair of edge bands covering the axially outer edges of the belt layer, and the pair of edge bands comprises one or more organic fiber cords, characterized in that the organic fiber cords of the pair of edge bands each have a restraining force in a range from 5 to 35 N at radially outward locations of the outer edges of the belt layer, wherein the restraining force is measured by taking out one of the edge bands from the tyre, obtaining the elongation of the edge band when it has been arranged in a tyre from the difference in length of the edge band before and after leaving the edge band taken out from the tyre to stand for 21 to 27 hours in an environment where the temperature is 18 to 22 degrees C, and the humidity is 61% to 69%, obtaining a relationship between the tension and the elongation of one organic fiber cord of the edge band by measuring the elongation in a tensile test in which tension is gradually applied to the organic fiber cord of the edge band, and obtaining the restraining force of the organic fiber cord of the edge band from said relationship and the obtained elongation of the edge band when it has been arranged in the tyre. a tread portion; a pair of sidewall portions; a pair of bead portions; a carcass extending between the pair of bead portions through the tread portion and the pair of sidewall portions; a belt layer disposed outwardly in a tyre radial direction of the carcass, the belt layer comprising at least two belt plies (7A, 7B); a band layer disposed outwardly in the tyre radial direction of the belt layer; and a pair of belt-edge rubbers disposed between the belt layer and the band layer to cover axially outer edges of the belt layer, wherein the band layer comprises at least one full band and a pair of edge bands covering the axially outer edges of the belt layer, and the pair of edge bands comprises one or more organic fiber cords, the organic fiber cords of the pair of edge bands each have a restraining force in a range from 5 to 35 N at radially outward locations of the outer edges of the belt layer, wherein the restraining force is measured by taking out one of the edge bands from the tyre, obtaining the elongation of the edge band when it has been arranged in a tyre from the difference in length of the edge band before and after leaving the edge band taken out from the tyre to stand for 21 to 27 hours in an environment where the temperature is 18 to 22 degrees C, and the humidity is 61% to 69%, obtaining a relationship between the tension and the elongation of one organic fiber cord of the edge band by measuring the elongation in a tensile test in which tension is gradually applied to the organic fiber cord of the edge band, and obtaining the restraining force of the organic fiber cord of the edge band from said relationship and the obtained elongation of the edge band when it has been arranged in the tyre. taking out one of the edge bands from the tyre, obtaining the elongation of the edge band when it has been arranged in a tyre from the difference in length of the edge band before and after leaving the edge band taken out from the tyre to stand for 21 to 27 hours in an environment where the temperature is 18 to 22 degrees C, and the humidity is 61% to 69%, obtaining a relationship between the tension and the elongation of one organic fiber cord of the edge band by measuring the elongation in a tensile test in which tension is gradually applied to the organic fiber cord of the edge band, and obtaining the restraining force of the organic fiber cord of the edge band from said relationship and the obtained elongation of the edge band when it has been arranged in the tyre.
