发明名称 空気入りタイヤ
摘要 PROBLEM TO BE SOLVED: To provide a pneumatic tire that can exhibit good rim-off resistance performance even when inner pressure of the tire drops.SOLUTION: The pneumatic tire comprises a carcass 6 having a carcass ply 6A leading from a tread part 2 through a side wall part 3 to bead cores 5 of bead parts 4. The bead cores 5 include an inner core 10 arranged inside in a tire shaft direction of the carcass ply 6A and an outer core 11 arranged outside in the tire shaft direction of the carcass ply 6. The carcass ply 6A is sandwiched between the inner core 10 and the outer core 11. The inner core 10 and the outer core 11 are constituted by being wound spirally with bead wires G plural times in a tire circumferential direction, and the winding number of the bead wires G around the inner core 10 is more than the winding number of the bead wires G around the outer core 11, in at least one bead part 4.
