PURPOSE:To prevent hydroplaning of an automotive tire having an antislipping device for a snow-covered road and the like by forming projections inclined to a circumferential direction on the surface of a tire along the full width thereof, reversing the inclining direction at the left and right tires, and also positioning the front ends of the projections at outer sides of an automobile. CONSTITUTION:Projections 5, 6 inclined to the rotational direction of a tire are formed along the full width of the tire. These projections 5, 6 are formed in reverse each other in left and right tires. Namely, the projections 5 of a right front wheel 1 and a right rear wheel 3 are in reverse to the projections 6 of a left front wheel 2 and a left rear wheel 4 in the inclining direction. The front ends (a), (b) of the projections 5, 6 are positioned at outer sides of a car body travelling in the direction of (e) respectively. According to this construction, dust generating pollution is not generated and also overturning at a corner and hydroplaning can be prevented. |
