Vehicle tires and methods for constructing a belt-tread package

Abstract

The invention relates to vehicle tires with a tread (1) having a ground contact surface and a belt assembly (2) with at least two belt layers (2a, 2b) each made of steel reinforcing elements (2c) embedded in an electrically non-conductive belt rubber, with a diameter (d1) determined in the radial direction at their thickest point, wherein the vehicle tire has a discharge path for dissipating electrostatic charges to the outer surface (1a) of the tread, which comprises the tread or an electrically conductive tread element (1e) penetrating the tread (1) to the ground contact surface and each an electrically conductive belt-rim connection (4, 7) which, in the case of vehicle tires mounted on the rim, contacts the rim.The belt assembly (2) has at least one central belt section (21) shaped in a trough towards the tire interior and tapered in the radial direction, which is formed from radially tapered layer sections (2a1, 2b1) of the belt layers (2a, 2b), wherein the tread or tread element (1e) is each electrically connected to the electrically conductive belt-rim connection (4, 7) via the tapered belt section (21).
