FIELD: transport.
SUBSTANCE: invention relates to structure of radial tire intended predominantly for vehicles carrying heavy cargoes and moving at high speed, for instance such as trucks, tractors, trailers or long-distance buses. Proposed tire consists of at least one ply of metallic reinforcement elements. The tire also contains flange reinforcement above which in radial direction tread is located, herewith the mentioned tread is connected with two beads via two sidewalls. At least 70% of reinforcement elements of at least one ply of bar-mat reinforcement are not tied up by cords and showing in so-called permeability test less than 20 cm3/min yield, herewith at least 1% of reinforcement elements of above mentioned at least one ply of reinforcement elements are capillary tubes. In section plane perpendicular to capillary tune axis, hole area to material area ratio exceeds 0.4%.
EFFECT: improvement of wear resistance and fatigue resistance of tire.
