The invention discloses a run-flat tire structure and a tire, and belongs to the field of tires. The run-flat tire structure comprises two symmetrical tire bead parts, tire bead cores are contained in the tire bead parts, each tire bead core comprises an inner side core, an outer side core and a middle core, and the inner side cores are arranged on the inner sides of the tire bead parts; the outer side core and the inner side core are arranged at an interval and are positioned on the outer side of the tire bead part; the middle core is arranged between the inner side core and the outer side core; the height of the inner side core, the height of the middle core and the height of the outer side core are sequentially decreased. The technical problem that an existing run-flat tire cannot give consideration to zero-air-pressure durability and riding comfort of the run-flat tire at the same time is solved, and the run-flat tire has the advantages that the zero-air-pressure durability of the tire can be met, and the riding comfort and NVH performance of the tire can be improved.
本发明公开了一种缺气保用轮胎结构及轮胎,属于轮胎领域。一种缺气保用轮胎结构包括两个对称的胎圈部,所述胎圈部内含有胎圈芯,所述胎圈芯包括内侧芯、外侧芯和中间芯,所述内侧芯设于所述胎圈部的内侧;所述外侧芯与所述内侧芯间隔设置且位于所述胎圈部的外侧;所述中间芯设于所述内侧芯和所述外侧芯的中间;其中,所述内侧芯、所述中间芯以及所述外侧芯的高度依次递减。本发明解决了现有缺气保用轮胎无法同时兼顾缺气保用轮胎的零气压耐久性和乘坐舒适性的技术问题,具有既能满足轮胎零气压的耐久性能,又能提升轮胎乘坐舒适和NVH性能的特点。
