多年以来,我国轮胎新产品都是根据用户的技术要求,参考国外技术资料而生产的,没有系列标准的约束,以致轮胎规格、品种和技术指标较为混乱,一些不符合系列的非标准轮胎,就是在这样的情况下产生的,它们缺乏通用互换性,影响了相互间的配合。并且品种不全、规格陈旧,与国外相比差距甚大,难以适应四化建设的需要,和不利于对外贸易。为此,国家标准总局、化工部、一机部和农机部组织了全国轮胎轮辋气门咀国家标准联合工作组,制订载重汽车充气轮胎、轿车充气轮胎、拖拉机与农业林业机械充气轮胎、工程机械充气轮胎和工业车辆充气轮胎的系列标准,对我国1985年以前的轮胎
Over the years, China’s new tire products are based on user’s technical requirements, reference to foreign technical information and production, there is no series of standard constraints, resulting in tire size, variety and technical indicators are more chaotic, some do not meet the series of non-standard tires, is Under such circumstances, they lack universal interchangeability and affect each other’s cooperation. And the variety is incomplete, the specification is out of date, there is a big gap compared with foreign countries, it is difficult to meet the needs of the four modernizations and is not conducive to foreign trade. To this end, the State Administration of Standards, Ministry of Chemical Industry, a machine department and the Ministry of Agricultural Machinery organized a national standard tire rims valve joint working group to develop a pneumatic truck tires, car pneumatic tires, tractors and agricultural forestry machinery pneumatic tires, construction machinery inflatable Tires and industrial vehicles pneumatic tires series of standards for our country before 1985 tires
