FIELD: transport.
SUBSTANCE: invention relates to pneumatic tire design, predominantly for heavy trucks, with radial bar-mat reinforcements. Tire tread is connected with two beads (3) via two sidewalls. Metal reinforcing elements of at least one layer of bar-mat reinforcement (2) are non-constricted cords, showing in so called test for permeability the yield of less than 20 cm3/min. In radial plane on at least a portion of tire meridional profile, resin mixture thickness (E) between inner surface of tire cavity and bar-mat reinforcement metal reinforcing element point nearest to the mentioned inner surface of tire cavity is less than or equal to 3.5 mm. Ratio between values of resin mixture thickness between inner surface of tire cavity and bar-mat reinforcement metal reinforcing element point nearest to the mentioned cavity inner surface of two different tire parts exceeds 1.15.
EFFECT: higher fatigue endurance of tire.
