摘要： Provided is a pneumatic tire. One terminal of a carcass layer extends to a ground contact edge of a tread portion positioned on an opposite side with respect to a tire center line as a reference. The carcass layer has a double layer structure including an inner layer positioned inward in a tire radial direction in a tread region and an outer layer positioned outward in the tire radial direction of the inner layer in the tread region. A cord angle in the carcass layer in a tread central region with respect to a tire circumferential direction is different from a cord angle in at least one of the inner layer and the outer layer of the carcass layer in a side region with respect to the tire circumferential direction.

摘要： Provided is a pneumatic tire. Both terminals of a carcass layer are overlapped with each other in a tread region. The carcass layer has a triple layer structure including an inner layer positioned most inward in a tire radial direction in the tread region, an outer layer positioned most outward in the tire radial direction in the tread region, and an intermediate layer positioned between the inner layer and the outer layer in the tread region. A cord angle in the carcass layer in a tread central region with respect to a tire circumferential direction differs in at least one of the inner layer, the outer layer, and the intermediate layer from a cord angle in the carcass layer in a side region with respect to the tire circumferential direction.

摘要： A pneumatic tire is configured in such a manner that at least two carcass layers each have both end portions in the tire width direction extending to bead cores disposed in both bead portions, and the both end portions are wound up from the inner side in the tire width direction of the bead cores to the outer side in the tire width direction, and extend outward in the tire radial direction. In such a pneumatic tire, the carcass layers are formed by thermoplastic sheets, and a rubber layer is disposed at least between adjacent sheets of the thermoplastic sheets.

摘要： Provided is a pneumatic tire including a belt layer. When the tread region indicates a region corresponding to a belt width of the belt layer and the side region indicates a region inward of a tire radial direction with respect to a tire maximum width position, the carcass cords forming the carcass layer are inclined with respect to the tire radial direction in the tread region, and at the same time, extend along the tire radial direction in the side region. The carcass cords forming the carcass layer and belt cords forming the belt layer cross with each other in the tread region.
