  • Patent number: 12049110
    Abstract: In a tire tread pattern, lug grooves with sipes each include: a lug groove and a first sipe further extending from the lug groove to a second circumferential main groove and pass through a land portion region. Second sipes are alternately disposed with the lug grooves with sipes in a circumferential direction and pass through the land portion region. The second sipes extend inclined with respect to a lateral direction in a direction opposite to a direction in the circumferential direction in which the lug grooves with sipes are inclined. At an opening end at which the lug groove opens to a first circumferential main groove, the lug grooves with sipes and the second sipes are joined. Thus, triangular blocks surrounded by the second circumferential main groove, the lug grooves with sipes, and the second sipes are disposed side by side in the land portion region in the circumferential direction.
