<p>PROBLEM TO BE SOLVED: To provide a pneumatic tire having especially improved on-snow performance without reducing on-ice performance.SOLUTION: The pneumatic tire is formed by arranging respective inclined grooves 3 extending toward a direction separating mutually in an inclined manner toward respective tread ends from the vicinity of a tire equator surface on a tread surface 1. Plural recesses 6 are provided on groove bottoms of the respective inclined grooves 3. Sub grooves 5 extending toward a tread circumferential direction or a tread width direction are disposed on the respective inclined grooves 3, in which groove width of the sub groove 5 is narrower than that of the inclined groove 3. In addition, groove bottoms of the sub grooves 5 are disposed continuously to the recesses 6 of the inclined grooves 3.</p> |
