<p>The invention relates to a pneumatic tire, which keeps the drainage through improving the tread shape and improves the operation stability as well as the uneven wearability. The tread part of the pneumatic tire (1) with pointed rotating direction comprises a crown pattern block (6), a pair of middle pattern blocks (7) and a pair of shoulder pattern blocks (8), wherein the crown pattern block (6) is formed by a pair of inside connection ditches (4) and a main tilting ditch (3); the pair of middle pattern blocks (7) is formed by the inside connection ditch, an outside connection ditch (5) and the main tilting ditch; and the pair of shoulder pattern blocks (8) is formed by the outside connection ditch, a grounding terminal (Te) and the main tilting ditch. The tire axial outermost end (6e) of the crown pattern block is located at 0.1-10.0mm position of the tire axial outside than the tire axial innermost end (7i) of the middle pattern block adjacent to the crown pattern block. Furthermore, the position (6B), which the tire axial width of the crown pattern block is the biggest width (BW), is formed in the firstly landing side area (S); and the distance between the firstly landing side area (S) and the end part (6s) of the firstly landing side of the tire rotating direction of the crown pattern block is 1/3 of the tire circumferential length (L1) of the crown pattern block.</p> |
