| abstract | PROBLEM TO BE SOLVED: To provide a tire having improved durability and low rolling resistance by using a reinforcing cord containing a polyamide multifilament as a reinforcing cord of a tire reinforcing member. SOLUTION: At least one of a carcass 1 and a belt reinforcing layer 3 is a polycondensate of a rubber and a dicarboxylic acid containing an aromatic dicarboxylic acid and a non-aromatic diamine, or a diamine containing a non-aromatic dicarboxylic acid and an aromatic diamine. It has a reinforcing cord containing a multi-filament of a semi-aromatic polyamide composed of a polycondensate of the above and a rubber-cord composite composed of the above as constituent elements, and the modulus per cord of the reinforcing cord is A (GPa), rubber-. When the number of cords driven per 50 mm width of the cord composite is B (lines / 50 mm) and the thickness of the reinforcing cord is C (mm). X = A × B Modulus X represented by is 100 GPa or more, Y = (50-B × C) / B The cord spacing Y represented by is 0.05 mm or more and 0.8 mm or less. [Selection diagram] Fig. 1 |
