FIELD: transportation.
SUBSTANCE: invention relates to wheeled vehicles of mainly special purpose. Tire comprises beads, bead rings, side pieces, tread, breaker made up of several layers of rubberized textile or metal cord, carcass with layers of rubberized cord with meridian direction of threads therein. Part of carcass layers is made half-layers, one edge of which is fixed on / at side rings, and the other one is located in the tread zone. Free edges of adjacent half-layers are not joined and inclination of cord threads in semi-layers is made in one side from meridian (meridian section) of tire at angle of 10–75 degrees.
EFFECT: improved operational properties of tire by increasing traction-grip properties at change of internal pressure in tire.
