    摘要: A pneumatic tire for a passenger car wherein a plurality of grooves are disposed on a tread surface to define and form land portions, and kerfs which are open to the grooves at at least one of the ends thereof are disposed on the land portions. At least one stage of step portion is disposed in a step shape on at least one of the groove walls of the grooves, and a plurality of kerfs are disposed on the step portion with smaller gaps than those of the kerfs disposed on the land portions.

    摘要: A pneumatic tire having a plurality of main grooves extending in the circumferential direction of a tread surface, and a plurality of auxiliary grooves each of which is disposed in the shape of the letter "V" and extended in one of the circumferential directions of the tread surface, the apexes of the V-shaped auxiliary grooves being distributed in left and right regions each extending from the equator of the tire as much as 5-25% of the width of a ground contacting portion of the tread surface, in such a manner that the numbers of the apexes in the left and right regions become substantially equal to each other, characterized in that quasi-main grooves each of which connects at least two circumferentially arranged auxiliary grooves together are provided in left and right regions each extending from the equator of the tire as much as 25-50% of the width of a ground contacting portion of the tread surface, in such a manner that the quasi-main grooves are inclined at an angle of 5.degree.-25.degree. with respect to the equator of the tire.
