载重胎无内胎国产化进程提速

Localization of Tubeless TBR Tire is under Rapid Development

汽车轮胎的发展经过了斜交轮胎、有内胎子午线轮胎、无内胎子午线轮胎和低断面无内胎子午线轮胎四个发展过程。在半个多世纪的发展过程中，前期发展极为缓慢，进入20世纪八十年代，随着子午线轮胎技术的日益成熟，轮胎产品更新换代速度迅速提高。

Tubeless TBR tire has unique benefit compared to ordinary tires.In terms of energy conservation and environmental protection,tubeless TBR tire has no inner tube and flap,hence no need for lock ring,making the total weight of a tire lighter with lesser raw material,especially for the reduction of rubber and wire consumptions.On the other hand,there is less friction between each part so that heat generated is reduced,w h i c h r e d u c e s t h e probability of damage at early stage,yielding better service life.
