A pneumatic commercial vehicle tire of radial design includes at least a three-ply belt, of which two belt plies are working plies and one radially outermost belt ply is a cover ply. Each of these belt plies includes reinforcements which are made of steel cord and which are embedded in elastomer. The steel cords of each of the three belt plies are coated with brass so as to provide for good elastomer adhesion. The brass coating of the reinforcement supports of the two working plies has a copper proportion of 60 wt. % to 65 wt. % and the brass coating of the reinforcement supports of the cover ply has a copper proportion of 66 wt. % to 70 wt. %.

Pneumatic vehicle tire, preferably pneumatic commercial vehicle tire

A tread profile has a tread profile section which is in the center of the tire in the axial direction, and in each case one shoulder profile section. The central tread profile section is composed of profile belts, and the shoulder profile sections each have a second profile belt. A circumferential groove is arranged in each case between a first profile belt of the central section and the profile belt of the shoulder section. The groove is formed with a web which is radially raised from the groove base and which divides the groove into a narrow first and a wider second section which has, at the groove base, a linear section of extent which merges, with a curvature radius Rand R, with the edges of the profile belt or of the web, wherein R&#x3e;R. The linear section of extent is at an angle of inclination &#x3e;0&#xb0;.

Tread profile of a pneumatic vehicle tire for utility vehicles

A pneumatic vehicle tire, in particular for heavy commercial trucks, having a tread with a number of circumferential grooves which run in the circumferential direction and which separate profile positives, such as block rows or profile ribs, from one another. The circumferential grooves are each bounded by a groove base and two groove edges. In order to effectively prevent the occurrence of tears at the groove base of the circumferential grooves, in particular at the groove base of the circumferential grooves which extend on the shoulder side, the groove base extends, viewed in cross section and in the axial direction, at an angle of inclination of 3 degrees to 15 degrees with respect to an envelope which encompasses the outer faces of the profile positives.
