HANKOOK TIRE & TECHNOLOGY CO., LTD.

A tire having a bead portion for improving transverse rigidity and durability may comprise: a bead bundle positioned on the bead portion of the tire; a bead filler having a lower end portion coupled to the upper surface portion of the bead bundle, the bead filler being disposed to extend from the bead bundle to a side wall; a carcass coupled to the inner surface of the side wall of the tire and disposed to extend such that the inner surface of the bead filler and the lower portion of the bead bundle are surrounded; an inner liner coupled to the inner surface of the carcass and disposed to extend to the bottom surface portion of the carcass; and rim cushion rubber coupled to extend from the lower inner surface of the inner liner to the bottom surface portion of the carcass, thereby surrounding one edge of the carcass.

An embodiment describes a low noise tire that reduces noise caused by air column resonance occurring in a main groove and has a fluid flow path to prevent a surface layer from being roughened during a mold casting process. A low noise tire according to an embodiment includes a plurality of blocks formed on a tread, a groove formed between the blocks and extending in a circumferential direction of a tire, protrusion portions including a plurality of protrusion bodies protruding from a bottom surface and a wall surface of the groove and extending along the groove, and fluid flow paths formed along the wall surface of the groove and configured to divide the protrusion portions while traversing the protrusion portions so that a fluid positioned between the protrusion portions moves.

In order to reduce noise energy, embodiments relate to a noise-reducing tire including lateral grooves formed in the lateral direction from the longitudinal grooves towards the sidewall, the lateral grooves widening in width towards the sidewall. A noise-reducing tire according to one embodiment comprises: side walls on opposite sides; a tread portion integrally connecting the outer circumferences of the side walls; a longitudinal groove concavely formed in the tread portion along the driving direction; and a lateral groove concavely formed from the longitudinal groove towards the side walls in the lateral direction, wherein the lateral groove expands in width towards the side walls, and the lateral groove comprises a tie bar connecting the inner walls of the lateral groove without being spaced apart from the longitudinal groove.

An embodiment provides a wheel module comprising: a body; a connection part which is rotatably coupled to the body, the connection part being rotatable in a first direction; a wheel body which is rotatably coupled to the connection part, the wheel body being rotatable in a second direction; and a wheel part which is arranged to be spaced apart from the wheel body and has an auxiliary tread portion having selectively adjustable internal pressure.

An embodiment relates to a tire in which kerf space can be secured after tread wear without a decrease in block rigidity. The tire provided with 3D kerfs combining interlocking bands and hidden groove-type kerfs according to an embodiment comprises: kerfs that are provided with road surface portions and bottom portions; and protrusion parts that protrude from one of the two side wall surfaces of the road surface portions, wherein the road surface portions are spaces extending, in the thickness direction of the blocks, from the outer surface of the blocks in contact with the road surface, and the bottom portions are spaces extending from the road surface in the thickness direction of the block.

In order to reduce noise energy, an embodiment provides a noise-reducing tire including lateral grooves 30 formed in the lateral direction from the longitudinal grooves 20 towards the sidewall 5 , the lateral grooves 30 widening in width towards the sidewall 5.

An embodiment relates to a tire in which kerf space can be secured after tread wear without a decrease in block rigidity. The tire provided with 3D kerfs combining interlocking bands and hidden groove-type kerfs according to an embodiment comprises: kerfs that are provided with road surface portions and bottom portions; and protrusion parts that protrude from one of the two side wall surfaces of the road surface portions, wherein the road surface portions are spaces extending, in the thickness direction of the blocks, from the outer surface of the blocks in contact with the road surface, and the bottom portions are spaces extending from the road surface in the thickness direction of the block.

Proposed is a tire including a pattern forming area provided on a sidewall to display a pattern of predetermined shape, wherein the pattern forming area is formed by continuously arranging a plurality of hexagon-shaped unit patterns, and the unit patterns existing on the edges of the pattern forming area are cut off in shapes to correspond to the shape of the pattern forming area.
