    Abstract: A pneumatic tire provided with a tread portion, at least one body ply, and at least two stabilizer plies interposed between the tread and body ply, the radially innermost of the stabilizer plies having reinforcing cords oriented at an angle of approximately 54.degree. to a meridian line of the tire to substantially eliminate ply steer force in the tire. The average angle of the reinforcing cords in all of the stabilizer plies may be made approximately 68.degree. to a meridian line of the tire to provide good cornering stiffness force characteristics in the tire.

    Abstract: A breaker assembly for interposition between the carcass and tread of a pneumatic tire, is disclosed. The breaker assembly is substantially annular and comprises a single ply having a first pair of fold regions which divides the ply into a substantially Z- or S-shaped array of three webs superposed upon and axially continuous with one another, and a second pair of fold regions which further divides the ply into two additional webs each of which axially terminates in a circumferential edge and is superposed upon at least one of the aforementioned three webs.

    Abstract: A two-ply tread-reinforcing breaker for a radial ply tire, each of the plies being folded and divided at their respective fold regions into a pair of webs. The webs of one ply define cooperatively with the webs of the other ply and S-shaped array in cross-section. The plies each have physical characteristics which differ from the other thereby imparting to the tire asymmetrical physical characteristics relative to a median equatorial plane of the tire.

    Abstract: Radial ply tires having good vertical flexibility as well as lateral stability even at high speeds are disclosed. The tires are characterized by a sidewall construction in which a radially inward zone in at least one sidewall is reinforced only by the ply structure of the radial carcass itself, and the respective adjacent radially outwardmost sidewall zone contiguous with the tread region of the tire is additionally reinforced by a supplementary ply structure of the carcass extending from the breaker region into the sidewall. In a preferred embodiment, the supplementary ply structure comprises sheet material folded back upon itself, with the folded edge defining the boundary between said sidewall zones. As a refinement of the invention, the respective adjacent radially inwardmost zone of the same sidewall contiguous with the associated bead region is also additionally reinforced by an extended bead turnup section folded back upon itself. The resultant intermediate sidewall zone of limited reinforcement, bounded by the proximate edges of the additional reinforcing plies in the two other zones, is of considerably reduced width with respect to the normal width of a sidewall between the proximate edges of the standard breaker and bead turnup, whereby the tire is somewhat rigidified but retains an optimum degree of flexibility. The sidewall region corresponding to the intermediate zone may also be reduced in thickness.
