The invention relates to a commercial vehicle pneumatic tyre of radial construction, comprising a carcass (1) and a belt (3) that consists of two belt layers (8, 9) having reinforcements made of steel cord functioning as working layers, wherein the steel cords of each belt layer (8, 9) each run at an angle alpha of between 15° and 30° to the circumferential direction (A-A), wherein the inclination of the steel cords of the radially inner working layer (8) is opposite to the inclination of the steel cords of the radially outer working layer (9). The invention is characterised in that the radially outer working layer (9) has a steel cord spacing (5) of > 1.00 mm, the radially inner working layer (8) has a steel cord spacing < 1.00 mm and the difference of the steel cord spacing (4, 5) between the radially outer working layer (9) and the radially inner working layer (8) is > 0.2 mm, wherein the steel cord spacing (4, 5) per 100 mm belt width is defined as follows: 100mm - number of steel cords * diameter of a steel cord. |
