Abstract

PURPOSE: An air-in tire for a vehicle is provided to minimize the resistance of air and to prevent noise by improving the pattern shape in a side wall portion of the tire. CONSTITUTION: The sectional shape of a thread(40) to form a knurling portion(4) is formed in a scalene shape. The shape is differed from the neighbor thread. A larger side(42) among each side(41,42,43) of the thread(40) is formed in the tip of a rotating direction of a tire. A shorter side(43) is formed in the tail of the rotating direction of the tire. Thereby, the resistance of air is minimized and the generation of noise is prevented.

Description

공기 저항을 억제시킨 자동차용 공기입 타이어 {Pneumatic tire for dwindling air resistance}Pneumatic tire for dwindling air resistance

본 발명은 공기 저항을 억제시킨 자동차용 공기입 타이어에 관한 것으로, 더욱 상세하게는 타이어의 사이드월부에 형성되는 무늬의 형상을 개선하여 공기의 저항을 최소화시키고, 소음 발생을 방지할 수 있게 하는 공기 저항을 억제시킨 자동차용 공기입 타이어에 관한 것이다.The present invention relates to a pneumatic tire for automobiles with reduced air resistance, and more particularly, to improve the shape of the pattern formed on the sidewall portion of the tire to minimize the resistance of the air, and to prevent the generation of noise The present invention relates to a pneumatic tire for automobiles with reduced resistance.

일반적으로 타이어의 트레드부 패턴은 타이어의 성능에 따라 다양한 패턴을 가지나 타이어의 사이드월부는 특별한 무늬가 없이 제조회사의 로고와 타이어의 성능을 알리는 문자 등이 각인되는 정도의 모양만을 가진다.In general, the tread portion pattern of the tire has a variety of patterns according to the performance of the tire, but the side wall portion of the tire has only a shape such that the logo of the manufacturer and the letters indicating the performance of the tire are carved without a special pattern.

그러나 소비자가 차량에 장착된 타이어를 볼 때에는 타이어의 트레드부 보다는 사이드월부에 더 많은 시선을 주게되고 사이드월부의 형상과 무늬를 보고 타이어를 선택하는 경우가 많음에 따라 최근에는 각 타이어 제조회사에서 사이드월부에 다양한 무늬와 모양을 표현하여 소비자의 시선을 유도하고 있다.However, when a consumer sees a tire mounted on a vehicle, more attention is given to the sidewall than the tread of the tire, and the tires are selected by the tire manufacturers in recent years as the shape and pattern of the sidewall are often selected. Various patterns and shapes are expressed on the moon to attract the eyes of consumers.
