PURPOSE:To give antislip performance and to improve traveling performance by forming grooves inclining to a circumferential direction from the center of a tire to the inside at the time of mounting the tire, forming the inclination of the grooves reversed for left and right tires, and positioning the inside end of the groove in a rear portion on the ground surface. CONSTITUTION:Grooves 5, 6 inclining relative to rotational direction are formed within a range from 1/2 to 4/5 of the width of the tire on the surface of the tire 1-4. The grooves 5, 6 are formed on portions to become insides at the time of mounting the tires on the car body, and also the grooves for right side times 1, 3 and for left side tires 2, 4 are formed in reverse directions to each other, and the inside ends (the central portion sides of the tire) of the grooves 5, 6 are formed to be rear side in a traveling direction (rearward inclining from the end of a tire side toward the center of the tire). According to this constitution, antislip performance is given to the tire and also traveling performance can be improved. |
