Abstract
A pneumatic tire (1) is provided with a cylindrical annular structure (10) that is disposed around the rotational axis and that has an outer surface and an inner surface, a carcass portion (12) at least a part of which is disposed on an outer side of the annular structure in a direction parallel to the rotational axis, the carcass portion (12) having a cord covered by rubber, a rubber layer (11) at least a part of which is disposed so as to face the outer surface of the annular structure, the rubber layer (11) including a tread portion, and a fiber (2) disposed between the annular structure and the rubber layer so as to suppress generation of a gas space between the annular structure and the rubber layer.
Claims23
A pneumatic tire comprising:
- a cylindrical annular structure that is disposed around a rotational axis and that has an outer surface and an inner surface, wherein the annular structure is made of a single metal plate member;
- a carcass portion at least a part of which is disposed on an outer side of the annular structure in a direction parallel to the rotational axis, the carcass portion having a cord covered by rubber;
- a rubber layer having an inner surface disposed so as to face the outer surface of the annular structure, the rubber layer including a tread portion;
- and
- at least one fiber so as to suppress generation of a gas space between the annular structure and the rubber layer, a diameter of the at least one fiber being not less than 0.03 mm and not greater than 1.00 mm;
- wherein
- the outer surface of the annular structure and the inner surface of the rubber layer are in contact with each other;
- the fiber is disposed on a contact surface between the outer surface of the annular structure and the inner surface of the rubber layer;
- at least a part of the carcass portion is disposed so as to face the inner surface of the annular structure;
- and
- the at least one fiber is disposed between the annular structure and the carcass portion so as to suppress generation of a gas space between the annular structure and the carcass portion.
