TIRE WITH IMPROVED BEADS Russian patent published in 2015 - IPC B60C15/04 B60C15/06 

FIELD: transportation.

SUBSTANCE: invention relates to tires of the passenger vehicles intended mainly for all-wheel drive models. The tire contains two beads with the circular reinforcing structural elements (70), and the frame reinforcing bar who is fixed in two beads by means of enclosing of the circular reinforcing structural element for formation in each bead of the main part (62) and the enclosing part (63). Each bead contains the filling cord (110) of the bead and the external tape (120). The filling cord (110) of the bead and the external tape (120) are made of rubber mix the elasticity module G' which is less or equal to 15 MPa, and the viscosity module G", such that G"[MPa]≤0.2·G [MPa]'-0.2 MPa, while the elasticity and viscosity moduli are measured at 23°C.

EFFECT: decrease of resistance to rolling and increase of rigidity of the tire at steering motion.
