Abstract

A pneumatic vehicle tire comprises a carcass, a tread strip, and a breaker arrangement arranged between the carcass and the tread strip. The breaker arrangment includes at least two breaker plies which have threads or cords which serve as load-carrying members and extend at an angle to the mid-circumferential plane of the tire. A breaker cover surrounds the breaker arrangement at least in the region of the breaker arrangement's axial side edges. The breaker cover has at least one cover ply consisting of threads or cords which extend at least substantially in the circumferential direction of the tire. The breaker cover is formed of a helically wound strip bandage. At least one respective ply separating cushion layer is present in each of the two axial side regions of the breaker arrangement.
