Title:
TIRE
Document Type and Number:
Japanese Patent JP2022057195
Kind Code:
A
Abstract:
To achieve both reduction of rolling resistance and improvement of wet traction performance.SOLUTION: Provided is a tire having one or more circumferential fine major grooves 21 whose groove width W1 opening to a tread surface of a tread part 20 is more than 1.0 mm and 4.0 mm or less, and which extend in a tire circumferential direction, and a plurality of sipes 24 communicating with the circumferential fine major grooves 21. The circumferential fine major grooves 21 include a widening part 212 whose groove width is widened in a region where a groove depth from a surface of the tread part 20 is 30% or more of the maximum groove depth, and a plurality of notch parts 213 disposed at a distance in the tire circumferential direction, and communicating from the surface of the tread part 20 to the widening part 212 by expanding on one side of a tire width direction. The sipes 24 communicate with the notch parts 213.SELECTED DRAWING: Figure 2
