<p>A pneumatic tire has an asymmetric tread pattern. The width of an outboard shoulder main groove (3) is 3 to 4 % of the tread width TW. The width of an inboard shoulder main groove (4) is 5 to 6 % of TW. The width of an outboard crown main groove (5) is 6 to 7 % of . The width of an inboard crown main groove (6) is 6 to 7 % of TW. In each of the grooves (4, 5, 6), an outboard groove face's angle ¸1 is more than an inboard groove face's angle ¸2, wherein 81 is 13 to 19 degrees, and 82 is 9 to 14 degrees. In the groove (3), an outboard groove face's angle ¸3 is 9 to 14 degrees, and an inboard groove face's angle ¸4 is 5 to 8 degrees. The tread portion (2) is provided with outboard shoulder lateral grooves (12) and outboard middle lateral grooves (16).</p> |
