Abstract

본 발명은 견인력과 제동력이 향상된 비공기압 폴리우레탄 스페어 타이어의 내구력 향상방법에 관한 것으로서, 종래 방법에 비해 접지면적은 변함이 없으면서도 접착면적이 증가되고 이로 인해 비공기압 폴리우레탄 스페어 타이어의 견인력과 제동력이 향상됨은 물론 그 내구성도 증가되는 특징이 있는 것이다.The present invention relates to a method for improving the durability of a non-pneumatic polyurethane spare tire having improved traction and braking force, and compared to the conventional method, the adhesion area is increased without changing the ground area, and thus the traction and braking force of the non-pneumatic polyurethane spare tire is increased. This improvement is, of course, its durability is also characterized by increased.
