Pneumatic vehicle tire with specified bracing plies and bracing bandage
Abstract:
Pneumatic vehicle tire includes at least two bracing plies arranged to intersect each other at an angle and including reinforcements of steel arranged substantially parallel to and at a distance from one another and embedded in a rubber material. Bracing ply reinforcements are oriented at an angle of 18° to 45° with the circumferential direction of the tire. A bracing bandage is also included having at least one ply with reinforcements of a non-metallic material arranged substantially parallel to and at a distance from one another and generally extending a circumferential direction of the tire. Bracing bandage reinforcements include a material with heat shrinkage properties. Under a predetermined extension of 1% in the longitudinal direction of the reinforcements, each bracing ply, has a tension of 2,000 N per dm of width.
