  • Publication number: 20180141388
    Abstract: A motorcycle tire is provided in a tread portion 2 with blocks including crown blocks 11 disposed in a tread crown region 3. The crown blocks 11 include first crown blocks 16 on the tire equator C, pairs of second crown blocks 17, and pairs of third crown blocks 18. The minimum axial distance L2 between the ground contacting top surfaces of the paired second crown blocks 17 is smaller than the maximum axial width L1 of the ground contacting top surface of the first crown block 16. The minimum axial distance L3 between the ground contacting top surfaces of the paired third crown blocks 18 is greater than the maximum axial width L1 of the first crown block 16.

  • Publication number: 20140209227
    Abstract: A motorcycle tire having a block pattern suitable for running on rough terrain is disclosed. Each middle block overlaps with one of crown blocks at least partially in the tire circumferential direction. The top face of each crown block has an axially long rectangular shape. The top face of each middle block has a substantially pentagonal shape having five sides which are an axially inner side extending in the tire circumferential direction, a pair of transverse sides inclined so that the circumferential distance therebetween is gradually increased, and a pair of axially outer sides inclined so that the circumferential distance therebetween is gradually decreased. In a ground contacting patch of the tire in its normally inflated loaded condition and at the camber angle of zero, only an axially inner part of the top face of each middle block contacts with the ground.
