FIELD: machine building.
SUBSTANCE: invention relates to automotive industry, in particular, to passenger cars tires. Tire comprises two beads (20), each of which contains, at least, one circular reinforcing structural element (70), and carcass stiffener (60) fixed in two beads by wrapping, in which every bead comprises filler (110) formed from rubber mixture. Filler passes in radial direction on distance DBE determined in radial direction from bead radial circular reinforcing structural element innermost point. DBE distance in radial direction is smaller than or equals to 10% of tire profile height H in radial direction. At least, one tire bead additionally comprises stiffener (140), formed from plurality of metallic reinforcement elements (145, 146, 147), oriented at angle, which is less than or equal to 10 degrees relative to direction along circumference.
EFFECT: technical result is reduced rolling resistance in combination with good durability.
