Standards Manual standardized 15° drop-center rim (width codes 5.25 to 9.75) with two rim flanges (2) and with two rim sections (3), each with a bead seat surface (3a), wherein the commercial vehicle tire has two bead regions with bead cores (4) and in each case one bead toe (6) and one bead contour on the outside of the tire and one on the inside of the tire, which bead contours adjoin one another at the bead toe (6), wherein each bead contour on the outside of the tire has a first segment (S1), which is in contact with the rim flange (2) when the commercial vehicle tire is mounted on the rim (1), and an outer contour region, which is at least partially in contact with the bead seat surface (3a) when the commercial vehicle tire is mounted on the rim (1).

Abstract: A commercial vehicle tire of a radial type of construction with a cross-sectional height of 135 mm to 200 mm, a load index of 121 to 154, a radial-ply casing with at least one casing ply composed of steel cords embedded in rubber and with bead regions with bead cores and bead fillers around which the casing ply runs so as to form turn-ups. The casing ply is reinforced with steel cords of the construction 1+6, wherein the core filament (1) has a diameter (d1) of 0.19 mm to 0.22 mm and the ply filaments (2) have coinciding diameters (d2) of 0.17 mm to 0.20 mm, wherein the diameter (d2) of the ply filaments (2) is less than the diameter (d1) of the core filament (1) by at least 0.01 mm and wherein, at the crown of the tire, the steel cords are arranged in the casing ply with 60 epdm to 75 epdm.

Abstract: 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. %.

Abstract: 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 R3 and R2, with the edges of the profile belt or of the web, wherein R3>R2. The linear section of extent is at an angle of inclination >0°.

Abstract: 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.

Abstract: Process for producing a pneumatic tire that includes an inner liner of a layer that is as air-impermeable as possible, at least one carcass ply provided with strength supports, horn profiles, bead cores, sidewalls, a belt assembly, and a tread. The process includes building-up a partial tire in a production part A, where the partial tire includes at least a carcass body that includes the at least one carcass ply provided with the strength supports, bead reinforcements and cores, core fillers and horn profiles, and an undertread, and shaping and at least partially vulcanizing the partial tire under an internal pressure in a vulcanization mold in a first vulcanization procedure. The process also includes determining a cross-sectional contour for a completed tire and an amount of surface and strength supports to be added to the partial tire prior to a production part B, and building-up the partial tire in the production part B by adding remaining tire components to produce a complete tire.

Abstract: A pneumatic vehicle tire includes a carcass, a bead with a bead core arranged in the bead, and a first sensor located within the bead. The first sensor delivers signals which are correlated to frictional forces transmitted by the pneumatic vehicle tire during operation. This sensor has a first end and a second end, wherein the first end includes a heel attached to the bead core and the second end extends radially outward from the bead core within the tire. A plurality of such sensors can be included in each tire, some for measuring longitudinal forces in a circumferential direction of the tire and others for measuring lateral forces in an axial direction of the tire.
