Patent ID: 10814678

Abstract:
A tire comprises a tread portion 2 comprising a shoulder main groove 5 extending on a side of a tread edge Te and comprising inner and outer groove walls 11 and 12. The inner groove wall 11 has an angle θ1 with respect to a tread normal line in a cross section of the shoulder main groove 5 periodically increasing and decreasing in a tire circumferential direction so as to comprise concave and convex wall portions 16 and 17 arranged alternately in the tire circumferential direction. The outer groove wall 12 has an angle θ2 with respect to a tread normal line in the cross section periodically increasing and decreasing in the tire circumferential direction so as to comprise convex and concave wall portions 22 and 21 arranged alternately in the tire circumferential direction. The angle θ2 is larger than the angle θ1 in any cross section of the groove.
