<P>PROBLEM TO BE SOLVED: To provide a winter tire appropriately demonstrating each of traction (gripping) characteristics, power characteristics, braking characteristics and handling characteristics while favorably demonstrating each of dry road performance, wear performance and noise level performance. <P>SOLUTION: A vehicle wheel tire includes a tire tread having a circumferential center tread region in which block elements are arranged in a symmetric pattern on opposite sides of a tire circumferential equatorial plane. The tread has one or more circumferential grooves bounded by edges of opposed block elements; and pairs of opposed block elements have a block edge facing the groove and an array of saw-teeth formed along the groove-facing edge of opposed block elements, the saw-tooth inclined in a radial direction. The saw-teeth provided to the block edge of one opposed block element incline in a direction opposite to the inclination direction of saw-teeth provided to the other block element. <P>COPYRIGHT: (C)2012,JPO&INPIT |
