HIGHLY EFFICIENT TIRE FOR VEHICLE WHEELS Russian patent published in 2008 - IPC B60C1/00 B60C9/18 B60C11/00 C08L21/00 C08K9/04 

FIELD: transport engineering; tire industry; highly efficient tires.

SUBSTANCE: proposed tire for vehicle wheels includes carcass structure of toroidal shape whose opposite side edges are coupled by corresponding right-hand side and left-hand side bead wires to form corresponding beads; breaker structure applied in outer relative to radius position relative to said carcass structure: tread band radially applied to breaker structure; at least one layer of cross-linked elastomer material applied in inner relative to radius position relative to said tread band; pair of side strips applied from side to opposite sides relative to carcass structure; at least one layer of cross-linked elastomer material has following characteristics: dynamic modulus of elasticity E¹ measured at 70°C not lower than 20 MPa, preferably, from 25 MPa to 50 MPa; ratio between modulus of elasticity at extension at 100% elongation (MIOO) and modulus of elasticity at extension at 10% elongation (MIO) not lower than 1.5, preferably, from 2 to 5. One layer of cross-linked elastomer material is preferably laid between tread band and breaker structure. Invention provides better characteristics of tire during operation at high driving speed and/or extreme driving conditions - rigid steering, simultaneously with satisfactory behavior at normal driving conditions - soft steering.

EFFECT: improved service characteristics of tire.
