FIELD: transport.
SUBSTANCE: invention relates to tire cord structure for carriers intended for transportation of heavy cargoes at high speed. Proposed tire consists of at least one ply of metallic reinforcement elements. At least 70% of metallic reinforcement elements of at least one ply of carcass reinforcements are untightened cords displaying at so-called permeability test wear rate smaller than 2 cm3/min. At least 10% of metallic reinforcement elements of at least one ply of carcass reinforcements are cords displaying at so-called permeability test wear rate smaller than 4 cm3/min.
EFFECT: higher fatigue resistance.
