본 발명은 배수성(wet성)과 제동성을 향상시킨 승용차용 래디얼 타이어에 관한 것이다. 종래에 있어서의 타이어의 패턴은 첨부된 도면 제1도에 도시된 바와 같이 타이어 원주상의 트래드부(1) 중앙에 일정한 깊이와 폭을 가지는 리브 그루브(20)가 형성되고, 이의 양측으로 러그 그루브(10)가 일정한 폭으로 형성되며, 러그 그루브(10)의 깊이는 숄더부(2) 측으로 갈수록 낮아지게 형성시켜 구성된 것이다. 그러나 이와같이 구성되는 트래드의 패턴은 러그 그루브(10)의 깊이가 숄더부(2) 측으로 갈수록 낮아짐에 따른 배수능력의 한계로 인하여 수막 현상(hydroplanning)이 조기 발생되는 문제점이 있는 것이다. 특히 그루브의 폭이 작은패턴이 한곳에 집중적으로 형성되는 타입의 타이어에 있어서는 배수의 문제가 매우 심각하게 대두되는 실정이다. 따라서 본 발명은 타이어의 트래드부에 형성되는 리브 그루브와 러그 그루브의 폭과 깊이를 크고 깊게 형성시켜 배수성과 제동성을 향상 시킬 수 있도록 한 것인바, 이를 첨부된 도면에 의하여 설명하면 다음과 같다. 첨부된 도면 제2도 및 제3도에 도시된 바와 같이 트래드부(1)의 중앙에 리드 그루브(20)가 형성되고, 이의 양측으로 러그 그루브(10)가 형성된 승용차용 래디얼 타이어에 있어서, 리브 그루브(20)의 선상에 접하는 리브 그루브(20)가 가지는 폭(wl)과 깊이(dl) 보다 더 큰폭 (w2)과 깊이(d2)를 가지는 리브 광폭부(21)를 형성 시키고, 리브 광폭부(21)에 연결되는 러그 광폭부(11)도 근접하는 러그 그루브(10)의 폭(w3)과 깊이(d3) 보다 큰 폭(w4)과 깊이(d4)를 이루는 러그 광폭부(11)를 형성시킨다. 또한 리브 광폭부(20)와 러그 광폭부(10)는 타이어의 원주상에 등 간격으로 6～25 정도의 범위내에서 형성 시키는 것이 바람직하며, 광폭부(10,20)의 사이 간격은 불규칙하게 형성 시킬 수도 있는 것이다. 그리고 리브 광폭부(20) 폭(w2)은 리브 그루브 폭(w1)의 1.2～1.8배의 크기로 형성 시키며, 깊이(d2)는 리브 그루브 깊이(d1)의 1.1～1.5배의 크기로 형성 시키는 것이 바람직하다. 또한 러그 광폭부(11)의 폭(w4)은 러그 그루브 폭(w3)의 1.2～1.8배의 크기로 형성 시키며, 깊이(d4)는 러그 그루브 깊이(d3)의 1.1～1.5배의 크기로 형성 시키는 것이 바람직하다. 이와같이 구성되는 본 발명은 노면과 타이어 사이의 물이 리브 광폭부를 통하여 러그 그루브 측으로 원활히 배수되며, 러그 그루브로 급수된 물은 다수의 러그 광폭부를 통하여 외부로 배출되어 타이어와 노면 사이에서의 수막 현상은 발생되지 않는 것이다. 본 발명에 따른 타이어를 전륜 구동인 승용차에 장착후 제동력을 시험한 결과 아래의 표1과 같은 결과를 얻을 수 있었다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a radial tire for a passenger car with improved wettability and braking properties. In the conventional tire pattern, as shown in FIG. 1 of the accompanying drawings, a rib groove 20 having a constant depth and width is formed at the center of the tread portion 1 on the circumference of the tire, and lug grooves are formed on both sides thereof. 10 is formed to have a constant width, the depth of the lug groove 10 is formed by forming the lower toward the shoulder (2) side. However, the tread pattern configured as described above has a problem in that hydroplanning occurs early due to the limitation of drainage capacity as the depth of the lug groove 10 decreases toward the shoulder portion 2. In particular, in the type of tires in which grooves having a small width are formed in one place, the problem of drainage is very serious. Therefore, the present invention is to improve the drainage and braking properties by forming the width and depth of the rib groove and the lug groove formed in the tread portion of the tire large and deep, as described with reference to the accompanying drawings. In the radial tire for a passenger car in which the lead groove 20 is formed in the center of the tread part 1, and the lug groove 10 is formed at both sides thereof, as shown in FIG. 2 and FIG. A rib wide portion 21 having a width (w2) and a depth (d2) larger than the width (wl) and depth (dl) of the rib groove 20 in contact with the line of the groove 20 is formed, and the rib wide portion The lug wide portion 11 forming the width w4 and the depth d4 larger than the width w3 and the depth d3 of the lug groove 10 also adjacent to the lug wide portion 11 connected to the lug wide portion 11 is formed. To form. In addition, the rib wide portion 20 and the lug wide portion 10 is preferably formed in the range of about 6 to 25 at equal intervals on the circumference of the tire, the interval between the wide portion (10, 20) is irregular It can be formed. The width w2 of the rib wide portion 20 is formed to be 1.2 to 1.8 times the width of the rib groove width w1, and the depth d2 is formed to be 1.1 to 1.5 times the depth of the rib groove depth d1. It is preferable. In addition, the width w4 of the lug wide portion 11 is formed to be 1.2 to 1.8 times the width of the lug groove width w3, and the depth d4 is formed to be 1.1 to 1.5 times the size of the lug groove depth d3. It is preferable to make it. In the present invention configured as described above, the water between the road surface and the tire is smoothly drained to the lug groove side through the rib wide portion, and the water supplied to the lug groove is discharged to the outside through the plurality of lug wide portions so that the water film phenomenon between the tire and the road surface is It doesn't happen. As a result of testing the braking force after installing the tire according to the present invention in a front wheel drive passenger car, the results as shown in Table 1 below were obtained.

이 표에 나타난 바와 같이 본 발명에 따른 타이어에 의하면 노면이 젖은 상태에서의 제동력이 현저하게 향상되어 빗길주행시 발생될 수 있는 대형사고를 미연에 방지할 수 있는 효과가 있는 것이다.As shown in this table, according to the tire according to the present invention, the braking force in the wet state of the road is remarkably improved, thereby preventing a large accident that may occur when driving on a rainy road.
