1results about How to "Improve on-snow performance" patented technology

The present application provides a tire that improves performance on snow and noise performance. The tire has a tread portion (2). A first intermediate transverse groove (11) is provided in an intermediate land portion (7) of the tread portion (2). The first intermediate transverse groove (11) includes a first groove portion (31), a second groove portion (32) inclined in the same direction as the first groove portion (31), and a third groove portion (33) located between the first groove portion (31) and the second groove portion (32) and inclined in the opposite direction to the first groove portion (31) with respect to the tire axial direction. The groove width of the first groove portion (31) increases from the third groove portion (33) toward the outside in the tire axial direction. The groove width of the second groove portion (32) increases from the third groove portion (33) toward the inside in the tire axial direction.
