RADIAL PLY PNEUMATIC TIRE CASING Russian patent published in 2004 - IPC

Abstract RU 2239568 C2

FIELD: tire industry.

SUBSTANCE: invention relates to pneumatic tires, particularly to radial-ply casing containing rubber-lined twisted metal cord or its combination with rubber-lined polyamide cord in breaker. According to invention, mass of reinforcement material in breaker, without consideration of mass of rubber in breaker is 10-20% of mass of casing. Positive result of use of proposed invention in tires 9.00Р-20 mod. O-4OБМ-1 and 0.25P-20 mod. Y-2 is obtained owing to 50-100% increase of tire run at minimum changes of cost of production. Invention makes it possible to create radial ply pneumatic tires containing rubber-lined twisted metal cord or its combination with rubber-lined polyamide cord in breaker.

EFFECT: increased wear resistance and run of tyre.
