Abstract
The pneumatic vehicle tire comprises a radial ply carcass, two side walls, a tread member and a belt or breaker comprising at least one cord layer. The tread member is composed of a base layer positioned closer to the tire axis and a cap layer arranged on top thereof. For particularly favorably affecting the rolling behavior of the tire the base layer forms a trough in which the cap layer is accommodated.
