目前世界发达国家轮胎已基本实现了子午化 ,而我国子午化率则只有 2 0 %左右。这不仅与我国轮胎产量列世界第三的地位极不相称 ,而且直接影响到 2 1世纪轮胎工业适应国民经济发展的需求和轮胎企业参与国际竞争的能力。因此 ,采取有效措施加快我国子午胎发展 ,促进轮胎产业升级 At present, the world’s developed countries’ tires have basically achieved radialization, while China’s radialization rate is only about 20%. This is not only inconsistent with China’s tire production ranks third in the world, but also directly affects the 21st century tire industry to meet the needs of national economic development and tire companies to participate in international competition. Therefore, effective measures are taken to accelerate the development of China’s radial tires and promote the upgrading of the tire industry.
