Pneumatic tire for e.g. passenger car, has insert with film layers, filaments and/or threads adhered to insert and embedded in rubber material, where layers, filaments and/or threads are made of material that has specific elastic modulus

摘要

The tire has a radial casing (3) guided in a bead area around a bead wire (5) by forming an upturned section, and a reinforced insert (9) inserted between an inner layer (4) and the casing in the area of each side wall (8). The insert has a set of film layers (10), filaments and/or threads adhered to the insert and embedded in a rubber material, where the layers, filaments and/or threads are made of a material that has elastic modulus of 2 to 200 giga Pascal. The layers, filaments and/or threads extend in axial direction in a cross-sectional area, and are at a distance from the casing.
