PURPOSE: To improve the rib form to improve the non-slip property on a wetted road surface by providing a thread profile consisting of a circumferential rib blocked by fine slits mutually separated by a circumferential groove and extending obliquely to the circumferential direction. CONSTITUTION: This tire has a tread profile 1 having a plurality of circumferentially extending profile ribs 2-8 separated by a plurality of circumferential grooves 10, 11, each rib 2-8 having fine slits 12, 13 extending obliquely to the circumferential direction. The center rib 2 is formed of two kinds of rib blocks 14, 15. The rib blocks 14, 15 are provided so as to be adjacent one another in the form turned along the circumferential direction by 180 deg.. The Rune-shaped raised surface of the rib 2 is extended by nose-like block parts 16, 17. The other profile ribs 3-6 are also formed of two kinds of rib blocks 24, 25; 34, 35 formed in the same manner. |
