FIELD: transportation.
SUBSTANCE: invention is attributed to pneumatic tire for which factor of H/S type has value exceeding 0.55 and which has radial reinforcement of frame and contains flange reinforcement formed by at least two flange working layers created of inextensible reinforcing elements intercrossing from one layer to another forming with circumferential direction the angles in the range of 10 to 45°. Tyre tread connected with two beads by means of two sidewalls is located over this radial frame reinforcement in radial direction. Crest reinforcement contains at least one layer of circumferential reinforcing elements. Value of ratio of crest block width at the end of shoulder area to crest block width at center circumferential plane is less than 1.20, and value of ratio of axial width of at least one layer of circumferential reinforcing elements to axial width of tire tread exceeds 0.5 and preferably exceeds 0.6.
EFFECT: tire strength and reliability is improving.
