                 Abstract: In response to the special requirements of electric car tires, we have independently developed
             a 235/45R18 tire. The main parameters of the tire's structural design are as follows: outer diameter of 662 mm,
             section width of 253 mm, tread width of 194 mm, tread camber height of 7.8 mm, bead contact diameter of
             460.7 mm, section horizontal axis position (H 1 /H 2 ) of 0.952473, tread pattern featuring asymmetric tread pattern,
             utilizing a five-pitch design, with a total of 41 composite pitches, and a tread pattern depth of 7.2 mm. In terms of
             construction design: the upper layer of the tread adopts highly wear-resistant and low rolling resistance tread
             rubber, while the lower layer adopts low heat generation transition rubber; the belt layer uses two layers of
             4×0.225UT high-strength steel cord with a cord density of 79 EPD. The manufacturing process employs a one-
             step building machine and a hydraulic hot plate curing press. The performance test results of the finished
             tires show that their key indicators, including outer edge dimensions, strength, bead unseating resistance,
             durability, high-speed performance, and rolling resistance, all meet or exceed national and corporate
             standards.

                                        国家协议签订,利好轮胎出口!
                                The signing of the national agreement proves a boon for tire exports
                  10 月 28 日,中国 — 东盟自贸区 3.0 版升级议定书签署,将进一步推动我国与东盟国家产供链的深度融合。
             据央视报道,以橡胶、轮胎这条产业链举例来说,今年前三季度,我国自东盟进口橡胶同比增长 40.7%,出口轮
             胎等汽车零配件增长了 19.8%。在全国最大的橡胶进口口岸青岛,一批批自缅甸、老挝等东盟国家进口的橡胶原
             料进入港区周边的仓库存储,待办结海关手续后,这些橡胶就会走进轮胎生产线。橡胶作为一种重要的工业原料,
             进口以后可广泛用于轮胎、输送带、密封件、橡胶管等工业制品及日常消费品制造,成为我国多条产业链的基础
             保障。有了充足的进口橡胶作原材料支撑,青岛及周边地区形成了完备的橡胶轮胎加工产业集群。在这里,橡胶
             被加工成各种轮胎,又出口到东盟国家为当地相关产业提供支持。
                 据赛轮集团股份有限公司销售支援总监孟海亮介绍,今年前三季度,公司出口东盟轮胎总值超过 13 亿元,
             同比增长了 25%,近年来,中国 - 东盟产业链供应链韧性显著增强,企业在加快走出去步伐的同时,由 “ 产品出海 ”
             向 “ 产业出海 ” 推进,形成全球化的产业布局。
