Abstract
A pneumatic tire including a resin layer on at least a portion of the tire inside surface, the resin layer being formed from a thermoplastic resin or a thermoplastic elastomer composition in which an elastomer is dispersed in a thermoplastic resin. The pneumatic tire is provided with a fastener including a base material formed from a thermoplastic resin and engaging elements formed on the base material. Additionally, the base material of the fastener is fixed to the resin layer via fusion bonding.
Claims25
A pneumatic tire having a resin layer on at least a portion of a tire inside surface, the resin layer being formed from a thermoplastic resin or a thermoplastic elastomer composition comprising an elastomer dispersed in a thermoplastic resin, comprising:
- a fastener including a base material formed from a thermoplastic resin and an engaging element formed on the base material, wherein
- the base material of the fastener is fixed to the resin layer via fusion bonding,
- the engaging element is a hook member or a loop member of a hook-and-loop surface fastener, or the engaging element has a female button form, a male button form or a groove form, and
- the fastener having an element forming region where the engaging elements are disposed and a non-element forming region where the engaging elements are not disposed, and the fusion bonding being disposed in the non-element forming region;
- and
- main grooves extending straight in a tire circumferential direction in a tread portion, and a plurality of rows of land portions partitioned by the main grooves;
- wherein
- the fastener is disposed in a region of the tire inside surface corresponding to the tread portion,
- the fusion bonding of the base material of the fastener is performed continuously or intermittently along the tire circumferential direction at positions in the tire width direction corresponding to the land portions, and
- the fusion bonding is not performed at positions in the tire width direction corresponding to the main grooves.
A method for manufacturing a pneumatic tire comprising:
- vulcanizing a pneumatic tire having a resin layer on at least a portion of a tire inside surface, the resin layer being formed from a thermoplastic resin or a thermoplastic elastomer composition comprising an elastomer dispersed in a thermoplastic resin;
- thereafter,
- disposing a fastener including a base material formed from a thermoplastic resin and an engaging element formed on the base material along the resin layer in a region of the tire inside surface corresponding to a tread portion, the engaging element being a hook member or a loop member of a hook-and-loop surface fastener, or the engaging element having a female button form, a male button form or a groove form;
- the fastener having an element forming region where the engaging elements are disposed and a non-element forming region where the engaging elements are not disposed
- fixing the base material of the fastener to the resin layer in a region of the tire inside surface corresponding to the tread portion by fusion bonding in the non-element forming region and continuously or intermittently along the tire circumferential direction at positions in the tire width direction corresponding to a plurality of rows of land portions partitioned by main grooves extending straight in a tire circumferential direction in the tread portion, without performing the fusion bonding at positions in the tire width direction corresponding to the main grooves.
