A pneumatic tire includes a tread, side walls, beads, a carcass, a belt layer, an inner-liner layer, and a sealant layer. The inner-side surface of the inner-liner layer to which the sealant layer is adhered has profile that satisfies L1<L2<L3, L15 mm, L29.5 mm, and L311 mm, where L1, L2 and L3 represent heights in a radial direction measured from a base height point to the inner-side surface of the inner-liner layer at positions located in an axially inward direction from an axial outer edge of the belt layer by 5%, 10% and 15% of a maximum width of the belt layer, and the base height point is a point on an axial-direction line through the intersection where a radial-direction line passing through the axial outer edge of the belt layer intersects the inner-side surface of the inner-liner layer.

In a tire 2, each load support layer 22 extends from a side portion 24 of the tire 2 to a radially inner side of a belt 14 at an inner side of a carcass 12. A ratio (SP/WB) of a width SP from an equator plane to an outer edge 48 of the load support layer 22, relative to a width WB from the equator plane to an edge of the belt 14, in an axial direction is equal to or greater than 0.1 and equal to or less than 0.6.

A pneumatic tire is provided where a profile line in a tire meridian cross section of a center land portion defined by circumferential grooves and located on a tire equator is curved projecting outward in a tire radial direction. A carcass layer and a reinforcing layer include a recess portion curved projecting inward in the tire radial direction in a bottom region of the center land portion.

A radial tire for an aircraft, the radial tire having a rim diameter of 20 inches or less includes a pair of bead portions; a pair of sidewall portions extending outward from the bead portions in a substantially radial direction; a tread portion that couples together respective radial outer ends of the sidewall portions; a toroidal carcass layer reinforcing a portion between bead cores embedded in the bead portions; a belt layer and a tread that are sequentially laminated on an outer side of the carcass layer in the radial direction, wherein a value M obtained by dividing a tire external diameter D by a distance L between bead heels of the bead portions is in a range of from 4.1 to 5.4.

Provided is a pneumatic tire having at least one carcass layer as a skeleton extending in toroidal shape over a pair of bead portions, at least one belt layer and a tread disposed on an outer side in the radial direction of a crown portion of the carcass. In a tire section in the widthwise direction in state where the tire is assembled to an application rim, ratio BD/BW of radius difference BD between radius at a center portion and radius at an end portion in the widthwise direction of an innermost layer of the belt layer, to width BW of the innermost layer, ranges from 0.01 to 0.04, and ratio TD/TW of radius difference TD between radius at a center portion and radius at an end portion of the tread in the widthwise direction of a tread ground surface, to tread ground-contact width TW, satisfies BD/BW<TD/TW.

A pneumatic tire (1), wherein an inter-cord distance (Gcl) between a circumferential reinforcing layer (145) and an inner-side belt ply (142) at a tire equatorial plane (CL), an inter-cord distance (Gcu) between the circumferential reinforcing layer (145) and an outer-side belt ply (143) at the tire equatorial plane (CL), an inter-cord distance (Gsl) between the circumferential reinforcing layer (145) and the inner-side belt ply (142) at end regions of the circumferential reinforcing layer (145), an inter-cord distance (Gsu) between the circumferential reinforcing layer (145) and the outer-side belt ply (143) at the end regions of the circumferential reinforcing layer (145) have a relationship such that 1.20(Gcl+Gcu)/(Gsl+Gsu)9.20.

A method of forming a belt structure for a tire includes providing a drum having a center section. A first drum edge is near a first edge of the center section and a second drum edge is near a second edge of the center section. A first end surface extends from the center section first edge to the drum first edge and a second end surface extends from the center section second edge to the drum second edge, and a radius of each end surface is smaller than the center section radius. A rubber strip reinforced by a plurality of cords includes an outer edge and an inner edge. The strip is wound about the drum, turning from a first winding angle to a second winding angle on an end surface to reduce the tension and length differential between cords at the outer edge and inner edge of the strip.

A tire (10) for a vehicle comprises a radially outermost working layer (41) which comprises at least one undulation (412) in line with a central rib (251) of the tread (2). The undulation (412) is radially on the outside of the points of the working layer (41) in line with the bottom face (243) of the circumferential groove (24) closest to the undulation (412) and has an amplitude of at least 1 mm. The undulation (412) is vertically in line above at least one local reinforcing layer (6) comprising reinforcing elements that are mutually parallel and make with the circumferential direction (XX) of the tire an angle of which the absolute value is at most equal to 5?.

A tire 1 for motorcycles comprises a carcass 6, a belt layer 7, and a tread rubber 2G. The belt layer 7 includes at least one reinforcing cord coated with rubber and spirally wound. In a meridian section passing through a tire rotational axis of the tire 1 in a standard state, a width BW of the belt layer 7 in a tire axial direction is in a range of from 60% to 80% of a tread width TW. The tread rubber 2G has a thickness at a tire equator (C) in a range of from 70% to 90% of thickness at tread edges (2t).

A pneumatic tire includes a carcass layer, a belt layer that is disposed on the outer side in the tire radial direction of the carcass layer, and a tread rubber that is disposed on the outer side in the tire radial direction of the belt layer. The pneumatic tire also includes at least three circumferential main grooves extending in the tire circumferential direction, and a plurality of land portions that are defined by these circumferential main grooves. The belt layer includes an inner-side cross belt and outer-side cross belt having belt angles of not less than 51 and not more than 80 as absolute values with respect to the tire circumferential direction, the belt angles having mutually opposite signs, and a circumferential reinforcing layer having a belt angle that satisfies a range of 5 with respect to the tire circumferential direction.
