A belt of a tire is configured with two resin-covered cords that are wound in a spiral pattern onto a carcass ply. Each of the resin-covered cords is configured by covering a reinforcing cord with a covering resin, and has a cross-section profile in a tire axial direction that is trapezoidal shape. The belt is configured by winding one of the resin-covered cords with its upper base side at a tire radial direction outer side, and winding the other of the resin-covered cords with its upper base side at the tire radial direction inner side between portions of the one of the resin-covered cords. Thus, join portions that are inclined toward different sides in the tire axial direction are alternately formed at a tire radial direction inner side along the tire axial direction in the belt.

A tire includes a body ply sheet having a rubber core defined by a top surface having a length and a width, a bottom surface having substantially the same length and width, and side surfaces having a common height. The body ply sheet includes reinforcement cords spaced 0.1-4.0 mm apart from each other and spanning the width of the body ply sheet. Bleeder cords are disposed on the body ply sheet and spaced are 8-12 cm apart from each other. Conductive cords are also disposed on the body ply and are spaced 20-80 cm apart from each other. At least one of the conductive cords has a first end and a second end, the first end being located in a region within a middle 80% of a width of the circumferential tread.

Provided is a pneumatic tire according to the present disclosure that is a pneumatic tire comprising, in a tread portion, an annular resin-coated belt comprising a cord and a coating resin with which the cord is coated, and the resin-coated belt comprises an easy-to-deform part having a thickness in a tire radial direction smaller than that of a surrounding part thereof.

A tire includes a pair of axially spaced apart annular bead cores, a carcass ply extending around both bead cores, a tread for engaging a contact surface and being disposed radially outward of the carcass ply, and a belt structure disposed radially between the carcass ply and the tread. The carcass ply includes a plurality of cords embedded in a polymer matrix. The carcass ply has a first radially upper surface and a second radially lower surface disposed opposite the first surface. The first surface defines first portions and second portions interspaced between each first portion. Each first portion has a thickness greater than each second portion thereby forming throated portions between each cord of the plurality of cords.

A pneumatic tire in which a side reinforcement layer formed of a treated member is arranged, the treated member formed by coating with rubber organic fiber cords extending parallelly to ply cords of a carcass ply of the carcass main body, only on a sidewall portion of a half portion on one tire widthwise side; a tire radial inner end of the side reinforcement layer is located on a side inner in the tire radial direction than a tire radial outermost position of a rim flange, and a tire radial outer end of the side reinforcement layer overlaps the belt by 5 mm or more in a tire widthwise direction; and the tread portion has one or more circumferential main grooves, and a contact width of a tire widthwise outermost land portion is larger than a contact width of a tire widthwise outermost land portion.

A method for manufacturing a bonded reinforcing textile filamentary element (48) comprising a core and a layer of strands is disclosed. The textile filamentary element in the natural state is assembled. A textile filamentary element in the natural state or pre-bonded textile filamentary element is obtained. The filamentary element in the natural state or pre-bonded filamentary element is coated with an external layer of at least one heat-crosslinkable adhesive composition. The filamentary element in the natural state or pre-bonded filamentary element that is coated with the external layer is thermally treated so as to crosslink the adhesive composition in order to obtain the bonded filamentary element (48). The steps of coating with and of thermally treating the external layer of the filamentary element in the natural state or pre-bonded filamentary element are carried out such that, for an elongation equal to 30% of the elongation at break of the filamentary element in the natural state, the tangent modulus of the bonded reinforcing textile filamentary element (48) is increased compared with the tangent modulus of the filamentary element in the natural state.

A method forms a butt joint between ends of first and second plies and splices the first and second plies together. The method includes the steps of: positioning a first splice edge of a first ply at a first location; positioning a second splice edge of a second ply at a second location, the second splice edge being left bare; wrapping a gum strip around the first splice edge such that the first gum strip forms a U-shaped structure in section that allows the first gum strip to extend from a first planar side of the first ply over the first splice edge to a second opposite planar side of the first ply; not wrapping a gum strip around the second splice edge; placing the first splice edge in abutting relationship to the second splice edge; and stitching the first splice edge to the second splice edge such that stitches each extend from the first planar side of the first ply, through the gum strip, to the first planar side of the second ply.

Disclosed is a conveying apparatus and method for conveying a tire layer, wherein the conveying apparatus includes a swivel conveyor with at least one endless belt or wire, a first pulley, a second pulley and a third pulley that define a minimal loop (L) for guiding the endless belt or wire along a conveying run and a return run, wherein the third pulley is arranged between the conveying run and the return run, and is swivable about a swivel axis (X) between a first swivel position and a second swivel position. The pivot position is chosen such that the length of the minimal loop when the third pulley is in the first swivel position is the same within a tolerance of less than 1 percent with respect to the length of the minimal loop when the third pulley is in the second swivel position.
