Patent ID: 11007821

Abstract:
A pneumatic tire includes a tread; sidewalls; and beads. Lug grooves are formed in the tread inclining symmetrically about an equator, an inclination angle α of the lug grooves relative to the lateral direction being 15°≤α≤45°. A width W1 of the lug grooves at the tread edge and an interval W2 between the lug grooves at the tread edge satisfying 0.7≤W1/W2≤1.5. Shoulder grooves connecting lug grooves are inclined in an opposite direction to the lug grooves have an inclination angle β relative to the lug grooves being 80°≤β≤100°, a center position of the shoulder grooves being 15% to 35% of tread width TW from the equator. An area A1 of the shoulder grooves and an area A2 of shoulder blocks satisfy 0.2≤A1/A2≤0.6. A groove area ratio of the tread is 0.4 to 0.7.
