Abstract: 본 발명은 승용차에 있어서 운행중 타이어 펑크 및 이상으로 인하여 승용차의 운행이 불가능하거나, 겨울철 눈으로 인하여 도로가 빙판길이 되어 승용차의 타이어 미끄러짐으로 인하여 안전운전이 불가능할 때를 대비하여 이를 대체하기 위하여 모든 승용차가 적재하고 다니는 보조 타이어 및 스노우 체인에 관한 사항이다. 
통상 승용차에 비상용으로 적재하고 다니는 보조용 타이어 및 스노우 체인에 있어서, 타이어 자체의 중량이 무거운 관계로 승용차의 연비에도 문제가 있으며, 특히 여성 운전자가 운행중 타이어의 펑크로 인한 타이어의 교체, 또는 겨울철 미끄럼 방지를 위하여 스노우 체인의 장착작업은 쉽지가 않다. 이러한 문제를 보다 용이하게 하기 위하여 신 보조용 타이어의 휠 프레임의 중심축을 상하로 이동 가변할 수 있도록 독립된 휠 프레임의 중심축을 만든다. 펑크난 타이어를 승용차에서 분리하지 않고, 펑크난 타이어의 휠 프레임의 중심축과 상기 신 보조용 타이어의 휠 프레임의 중심축을 가변 이동하여 중심축과 중심축이 일치하도록 높이를 조정한 후, 승용차의 펑크난 타이어의 외측에 신 보조용 타이어를 부착한다. 신 보조용 타이어 휠 프레임의 중심축이 펑크난 타이어 휠 프레임 중심축의 외측에 부착이 완료되면, 신 보조용 타이어의 중심축을 신 보조용 타이어의 휠 프레임의 중심으로 이동한 후, 중심축을 보조용 타이어의 휠 프레임에 완전히 고정한다. 신 보조용 타이어의 중심축이 휠 프레임 중심에 완전히 고정되면 승용차는 신 보조용 타이어에 의해 균형이 유지되고 승용차는 타이어의 정비소가 있는 곳까지 안전운전이 가능한 상태가 된다. 겨울철 눈으로 인한 빙판으로 미끄러짐이 발생하여 승용차의 안전운전에 영향이 있을 경우에는, 먼저 신 보조용 타이어의 스노우 체인 장착 홀에 신 보조용 타이어용으로 제작된 스노우 체인을 장착한 후, 상기와 같은 방법으로 스노우 체인이 장착된 신 보조용 타이어를 승용차의 구동부 타이어의 좌우 외측 측면에 부착하면 빙판길에서도 안전운전을 할 수가 있다. 
이와 같은 구조의 신 보조용 타이어는 타이어 펑크 시, 기존의 타이어를 분리하지 않고, 기존 타이어의 외측 측면에 부착하여 사용할 수 있으므로 여성도 쉽게 장착할 수 있는 신개념의 신 보조용 타이어에 관한 사항이다.
