Abstract: A tire includes a tread portion being provided with circumferential grooves extending continuously in a zigzag manner. One of the circumferential grooves includes first inclined elements inclined in a first direction with respect to the tire circumferential direction, second inclined elements inclined in a second direction opposite to the first direction with respect to the tire circumferential direction, and intersections where the first inclined elements and second inclined elements intersect. Each of the first inclined elements and the second inclined elements is provided with at least one first protrusion that projects outwardly in a tire radial direction from the groove bottom and connects the pair of groove walls. At least one of the intersections is provided with a second protrusion that projects outwardly in the tire radial direction from the groove bottom and is separated from the pair of groove walls.

Abstract: A vehicle tire has outer shoulders and two tread halves. The tire includes a tread having six block rows and a plurality of circumferential grooves. Mutually adjacent ones of the block rows are separated from each other by a corresponding one of the plurality of circumferential grooves. Each of the block rows has individual blocks separated from each other by mutually parallel essentially straight transverse grooves running at an angle to the axial direction of the tire. The circumferential grooves include first circumferential grooves having a maximum profile depth and second circumferential grooves having a second profile depth less than the maximum profile depth. The transverse grooves have a depth approximately corresponding to a maximum profile depth at first outlet locations. The transverse grooves have a depth corresponding to the second profile depth at second outlet locations.

Abstract: A heavy duty pneumatic tire includes a tread portion provided with circumferentially extending zigzag shaped main grooves, a plurality of land portions separated by the main grooves, and a plurality of lateral grooves to form a plurality of block elements on each land portion. Each land portion comprises a number of pitches in a range of from 40 to 50, wherein each pitch consists of one block element and one lateral groove adjacent to the concerned block element. Each block element has a length in a range of from 85% to 95% of a length of the pitch. The main grooves include a crown main groove, a shoulder main groove, and a middle main groove. The middle main groove has a zigzag amplitude larger than those of the crown main groove and the shoulder main groove.
