Abstract: Tire including at least one carcass reinforcement of at least one ply anchored in each bead B to at least one bead wire, each bead being reinforced by at least two reinforcement plies formed of reinforcing elements inclined relative to the circumferential direction at an angle between 10° and 30°, said reinforcement plies being axially adjacent to the carcass ply wherein the reinforcing elements of at least one ply of the carcass reinforcement, in each part adjacent to the two bead reinforcement plies, are inclined relative to the circumferential direction at an angle between 50° and 80° and are radial in the part located between the radially upper ends of said two reinforcement plies, said ends being located radially outside the sidewall points that define the maximum axial width of the tire when mounted on its intended wheel rim and inflated.

Abstract: A pneumatic tire having an inboard sidewall and an outboard sidewall when fitted to a vehicle including a reinforced carcass extending between bead regions through both inboard and outboard sidewalls and a tread region reinforced by a breaker extending between the tread edges beneath the rubber tread wherein the carcass in the outboard sidewall comprises a single ply of reinforced material having mutually parallel reinforcement cords extending substantially radially of the tire, the ply having one edge located under the breaker, extending from the breaker radially inwards through the outboard sidewall and being wrapped axially outwards around a bead hoop and being turned up to have its second edge radially outwards of the bead hoop, and the reinforced carcass for the inboard sidewall comprises a single ply of reinforcement material arranged with a first edge under and in overlapping engagement with the edge region of the outboard sidewall reinforcement, said first edge being adjacent to the inboard bead at an

Abstract: A pneumatic motorcycle tire provided with a spiral belt and a pair of axially spaced reinforcing layers radially inside of the belt to improve the cornering stability and straight running stability of a motorcycle.

Abstract: In a pneumatic vehicle tire of a divided carcass the reinforcement elements are arranged at different angles of orientation. They may be provided as a combination of the same or different materials, the same or different cord constructions, the same or different packing densities. The overlap area of two adjacent carcass layer sections represents a transition area of a gradually stepped stiffness. The overlap area represents a constructive discontinuity and is employed for influencing the force fluctuations. The divided carcass which is essentially a sounding board may also be influenced by differently constructed carcass layer sections. The manufacture of such a divided carcass is inexpensive.

Abstract: A pneumatic tire (10) has adjacent carcass plies (13, 14, 15) which are reinforced by cables comprising aramid filaments. The amount of strength retained by the cables over a period of normal use of the tire is increased when for each pair of adjacent carcass plies: (a) the cables of the radially innermost of said carcass plies intersect the mid-circumferential plane (CP) of the tire at a first angle in the range of 75.degree. to 105.degree. and the cables of the radially outermost of said carcass plies intersect the mid-circumferential centerplane (CP) at a second angle in the range of 75.degree. to 105.degree.; (b) said second angle is nearer to 90.degree. than said first angle; and (c) the included angle between said first and second angles is not greater than 10.degree..

Abstract: A reinforcement for the butt splice of the carcass ply of a radial tire, is described as having two sets of polymeric cords or strands which are in cross-hatched relation and which cross adjacent reinforcement cords of the carcass ply at opposite angles A and B of 45.degree.. These strands pantograph in response to radial or circumferential forces exerted against the tire, to resist relative movement between opposing abutting ends of the carcass ply and butt splice.

Abstract: In a pneumatic tire of a structure in which a belt-reinforcing layer is overlaid and interposed between a tread and a carcass cord layer, the belt-reinforcing layer consisting of a transient-reinforcing layer positioned in contact with the carcass cord layer with its reinforcing cords disposed at an angle of between 40.degree. to 75.degree. with respect to the circumferential direction of the tire, and at least two belt-resistant layers, the lower one thereof being laid over the transient-reinforcing layer with its reinforcing cords disposed at an angle of between 15.degree. to 30.degree. with respect to the circumferential direction of the tire, and the upper one with its reinforcing cords disposed at an angle of between 150.degree. to 165.degree. thereto, the tire is improved in that the carcass cord layer is formed of a single layer and the reinforcing cords in the carcass cord layer are arranged so that their angle with respect to the circumferential direction of the tire is between 75.degree. to 85.
