Abstract: A pneumatic tire having high uniformity is provided by using a high-strength and high-modulus polyketone fiber cord to form a high-performance and high-quality cord fabric as a reinforcing cord in a carcass layer, a belt layer, or a belt protection layer and applying the cord fabric to the carcass layer, the belt layer, or the belt protection layer.A cord of the carcass layer contains at least 50% by mass polyketone fiber and has a maximum thermal shrinkage stress in the range of 0.1 to 1.8 cN/dtex. Weft cords within the tire substantially orthogonal to the carcass ply cord have a fineness in the range of 60 to 600 dtex, a tensile force in the range of 100 to 2000 g, and an elongation at break in the range of 3% to 30%. The distance between the weft cords substantially parallel to each other ranges from 5 to 50 mm.
