Abstract

A method of processing a vehicle tyre and a thixotropic balancing substance (251, 261), comprising providing a first amount of the balancing substance (251, 261) to a first circumferential balancing area (250, 260) on an inner side of the vehicle tyre comprising distributing the first amount of the balancing substance on the first balancing area substantially uniformly; and a corresponding apparatus and system. In one embodiment a varnish layer comprising manoparticles (252, 262) is provided on the first circumferential balancing area (250, 260) to increase the movability of the thixotropic balancing substance (251, 261) on the balancing area (250, 260).

451;

651) as a first strand (654) of balancing substance and a second strand (655) of balancing substance, wherein the first strand (654) of balancing substance is optionally provided intermittent with the second strand (655) of balancing substance, wherein a cross section of the first strand (654) of balancing substance or the second strand (655) of balancing substance or both is optionally circular, semicircular, flattened, triangular, quadrilateral or polygonal;

determining the first amount of the balancing substance (251;

351;

451;

651) from a characteristic of the tyre (20;

30;

40;

60), for example a size, type or model of the tyre (20;

30;

40;

60);

determining the first amount of the balancing substance (251;

351;

451;

651) from a feature of the tyre (20;

30;

40;

60), for example a code or bar code on the tyre, or an electronic identification or radio-frequency identification (RFID) on or in the tyre (20;

30;

40;

60);

or

a combination thereof.

8. The method of claim 1, further comprising:

mounting the tyre (20;

30;

40;

60) to process the tyre (20;

30;

40;

60), wherein mounting the tyre optionally comprises;

holding, for example gripping, spanning or clamping, an outer side, for example a circumferential tread surface (210;

310;

410;

610), of the tyre (20;

30;

40;

60) or circumferential bead portions (225, 236;

325, 335;

425, 435;

625, 635) of the tyre (20;

30;

40;

60);

opening out circumferential bead portions (225, 235;

325, 335;

425, 435;

625, 635) of the tyre (20;

30;

40;

60), wherein opening out the bead portions (225, 235;

325, 335;

425, 435;

625, 635) is optionally partial or complete;

removing old balancing substance (601) from the tyre (20;

30;

40;

60), wherein removing old balancing substance (601) optionally comprises;

cleaning out, for example loosening, rinsing or suction cleaning, the old balancing substance (601);

inserting a delimiter (471;

671) into the tyre (20;

30;

40;

60), the delimiter (471;

671) defining a first border of the first balancing area (250;

350;

450;

650), wherein inserting the delimiter (471;

671) optionally comprises;

pre-processing a delimiter area (470;

670) on the inner side (240;
