Abstract
A tire tread includes a pair of first circumferential main grooves in a first half-tread region on one side in a tire width direction, a pair of second circumferential main grooves in a second half-tread region, first sipes provided in a first region between the first circumferential main grooves, a circumferential narrow groove having a groove width smaller than a groove width of the first circumferential main groove and extending in the tire circumferential direction within the first region, and sipes in a second region between the second circumferential main grooves, extending in the tire width direction, and closing within the second region. The number of intervals of the second sipes mutually adjacent is larger than the number of intervals of the first sipes mutually adjacent.
Claims14
A tire comprising a tread pattern on a surface of a tread portion that contacts a road surface,
- the tread pattern comprising:
- a pair of first circumferential main grooves provided in a first half-tread region on one side of a tire centerline in a tire width direction, extending in a tire circumferential direction, and disposed at intervals from each other in the tire width direction;
- a pair of second circumferential main grooves provided in a second half-tread region on an other side in the tire width direction, extending in the tire circumferential direction, and disposed at intervals from each other in the tire width direction;
- a plurality of first sipes provided in a first region between the first circumferential main grooves, communicating with one of the first circumferential main grooves, extending in the tire width direction, and closing within the first region;
- a circumferential narrow groove having a groove width smaller than a groove width of the first circumferential main grooves and extending in the tire circumferential direction within the first region;
- and
- a plurality of second sipes provided in a second region between the second circumferential main grooves, communicating with one or an other of the second circumferential main grooves, extending in the tire width direction, and closing within the second region, and
- a number of intervals of the second sipes adjacent in the tire circumferential direction being larger than a number of intervals of the first sipes adjacent in the tire circumferential direction;
- wherein
- each sipe of the plurality of first sipes and the plurality of second sipes has a sipe width in a range of from 0.3 mm to 1.0 mm, and
- the second sipes comprise a second sipe A and a second sipe B, the second sipe A communicating with one of the second circumferential main grooves and the second sipe B communicating with an other of the second circumferential main grooves at a location, in the tire circumferential direction, which is different from a location, in the tire circumferential direction, where the second sipe A communicates with the one of the second circumferential main grooves.
A tire comprising a tread pattern on a surface of a tread portion that contacts a road surface,
- the tread pattern comprising:
- a pair of first circumferential main grooves provided in a first half-tread region on one side of a tire centerline in a tire width direction, extending in a tire circumferential direction, and disposed at intervals from each other in the tire width direction;
- a pair of second circumferential main grooves provided in a second half-tread region on an other side in the tire width direction, extending in the tire circumferential direction, and disposed at intervals from each other in the tire width direction;
- a plurality of first sipes provided in a first region between the first circumferential main grooves, communicating with one of the first circumferential main grooves, extending in the tire width direction, and closing within the first region;
- a circumferential narrow groove having a groove width smaller than a groove width of either of the first circumferential main grooves and extending in the tire circumferential direction within the first region;
- and
- a plurality of second sipes provided in a second region between the second circumferential main grooves, communicating with one or an other of the second circumferential main grooves, extending in the tire width direction, and closing within the second region, and
- a number of intervals of the second sipes adjacent in the tire circumferential direction being larger than a number of intervals of the first sipes adjacent in the tire circumferential direction;
- wherein
- each sipe of the plurality of first sipes and the plurality of second sipes has a sipe width in a range of from 0.3 mm to 1.0 mm, and
- the first sipes communicate with the circumferential narrow groove.
