Embodiment Construction

[0013] The height hi (i=1 to 3) specified below is measured in the radial direction from a line extending through the apex X of the rim in the axial direction.

[0014] Among the components of utility vehicle tires, figure 1 Single-ply or multi-ply carcass inserts 4 showing a gas-impermeable inner layer 1, sidewalls 2, corner profiles 3, steel cords or similar strength materials as reinforcing members, tires composed of tensile steel wires The bead core 5 , and the two core profiles 6 and 7 sitting on the bead core 5 . The sidewall 2 overlaps the corner profile 3 on the outside.

[0015] The core profiles 6 and 7 can be produced from the same or different rubber mixtures. A flipper 8 consisting of a textile reinforcement preferably embedded in rubber is laid around the bead core 5 so as to embed a carcass extending from a belt (not shown) and wrapped around the bead core 5 from the inside out. The part 4 is separated from the bead core 5 , whereby direct contact between the...

Abstract

A utility vehicle tyre which is of a radial design and which is embodied as an oblique shoulder tyre, having an airtight inner layer (1) which is, if appropriate, combined with a filler profile (11), a single-layer or multi-layer carcass inlay (4) with strength carriers made of steel cord or a material with a similar strength, wherein the carcass inlay (4) is turned over in bead regions around bead cores (5) to form carcass turn ups (4a), wherein in each bead region a steel cord bead reinforcer (9) runs on the outside of the carcass inlay (4), runs around the bead region and has a section (9a) running on the outside of the tyre and a section (9b) running on the inside of the tyre. Running between the inner layer (1) or between the filler profile (11) and the section (9b) of the steel cord bead reinforcer (9) which runs on the inside of the tyre and the section of the carcass inlay (4) which adjoins this section (9b) in the radial direction is at least one reinforcement layer (12) having textile strength carriers embedded in a rubber mixture, the strength carriers of which reinforcement layer (12) run parallel to the strength carriers in the carcass inlay (4).

Description

technical field [0001] The invention relates to a utility vehicle tire of radial construction in the form of a bias bead seat tire with an air-impermeable inner layer, possibly in combination with filler profiles, with a single-ply or multi-ply tire A carcass insert having a reinforcing member composed of steel cords or a material of similar strength, wherein the carcass insert is a turned-up bead core in the bead region to form a carcass turn, wherein, In each bead area, in each case a steel cord bead reinforcement extends on the outside of the carcass insert, the steel cord bead reinforcement extending around the bead area and having a A section extending on the outside of the tire and a section extending on the inside of the tire. Background technique [0002] A tire of the type mentioned in the introduction is known from DE 10 2010 016 007 A1. The tire has a fork-shaped profile consisting of three elements, two of which cover the end of the bead reinforcement of steel ...
