Provided is a pneumatic tire. A partial tie rubber layer is selectively disposed between a carcass layer and an inner liner layer in an area on a tread portion on either side in a tire lateral direction excluding a center region of the tread portion such that a length of intrusion from a perpendicular line extending from an outermost edge of a belt layer in a tire lateral direction through the inner liner layer toward a tire equator of each of the partial tie rubber layers is within the range from 0 to 15 mm and a length of protrusion from the perpendicular line toward a bead portion of the partial tie rubber layer is within the range from 15 to 120 mm.

A pneumatic tire mounted with surface fastener members for attaching an object to a tire inner surface, comprises: at least eight surface fastener members having an intermittent arrangement on a tread inner circumferential surface, the surface fastener members having a uniform cross-sectional dimension, an overall band-like shape, and a length in a tire axial direction from 50% to 120% of a maximum belt width of the pneumatic tire; wherein an angle θ between a longitudinal direction of the surface fastener members and the tire axial direction is from 0 degrees to 45 degrees; and an installation period in a tire circumferential direction is from 80% to 150% of the length in the tire axial direction of the surface fastener members.

Vehicle pneumatic tyre comprising a sealant layer, and method for detecting a vehicle pneumatic tyre comprising a sealant layer and for recycling a vehicle pneumatic tyre comprising a sealant

A run-flat tire includes side reinforcing rubbers provided along tire width direction inner side surfaces of carcass side portions. A first inner liner is provided along a tire radial direction inner side surface of a carcass central portion and tire width direction inner side surfaces of the side reinforcing rubber. Both end portions of the first inner liner run along a contour in a cross-section along a tire rotational axis direction and are respectively formed further toward a tire radial direction outer side than tire radial direction inner side end portions of the side reinforcing rubber. A second inner liner extends along a surface, which is at a side opposite from the carcass central portion, of the first inner liner. Both end portions of the second inner liner are respectively formed further toward a tire radial direction inner side than the both end portions of the first inner liner, along a contour in a cross-section along the tire rotational axis direction.

The present invention provides a pneumatic tire including a sealant layer that has excellent tear resistance despite its being formed of a generally string-shaped sealant provided continuously and spirally along an inner periphery of the tire. Included is a pneumatic tire including an innerliner and a sealant layer located radially inside the innerliner, the sealant layer including a first sealant layer and a second sealant layer stacked in that order from the innerliner, the first sealant layer including a generally string-shaped sealant provided continuously and spirally along an inner periphery of the tire, the second sealant layer including a generally string-shaped sealant provided continuously and spirally along the first sealant layer, the sealant of the first sealant layer and the sealant of the second sealant layer extending in directions crossing each other.

A method of preparing a tire with self-sealing properties, the method including the steps of providing a cured tire, the tire including a first bead, a second bead, a carcass layer extending from the first bead to the second bead, and an optional innerliner layer disposed interior to the carcass layer; directly or indirectly applying a sealant composition to at least a portion of the carcass layer or to at least a portion of the optional innerliner; and directly applying an air barrier composition to at least a portion of the carcass layer or to at least a portion of the optional innerliner.

To provide a pneumatic tire 34 in which weight reduction is achieved without deteriorating internal pressure maintaining performance. The tire 34 includes a liner 46 located inward of a carcass 42. The liner 46 includes a first inner liner 66 extending on and between one of beads and the other of the beads and along and inward of the carcass 42; and a pair of second inner liners 68 extending from ends 62a of a belt 44, respectively, along the first inner liner 66 substantially inward in a radial direction. The second inner liners 68 are located between the first inner liner 66 and the carcass 42. The first inner liner 66 is formed by a first rubber composition being crosslinked. A base rubber of the first rubber composition includes a butyl rubber. Each second inner liner 68 is formed by a second rubber composition being crosslinked. A base rubber of the second rubber composition includes a diene rubber.

A pneumatic tire includes a tread, sidewalls extending from edges of the tread, clinches extending from the edges of the sidewall, beads positioned on axially inner side of the clinches, a carcass bridging the beads along inner side of the tread and sidewalls, and load support layers positioned on axially inner side of the carcass such that the layers are positioned between the tread and beads. Each bead includes core and main apex, the core has radially outer side surface facing radially outward, the carcass includes carcass ply turned up around the core from inner side toward outer side in axial direction of the tire such that the main portion and turn-up portion are formed in the ply, the turn-up portion has core laminating portion laminated on the radially outer side surface of the core, and the apex is extending radially outward from radially outer side of the laminating portion.
