Rubberised rigidity support

Reinforcing material, which is covered at least partially or completely with a topping rubber layer comprising a rubber mixture including at least one diene rubber, at least one functionalized liquid polymer with an average molecular weight of 10000-100000 g/mol and at least one silicic acid and other additives, is claimed. Independent claims are also included for: (1) rubber articles comprising at least one reinforcing material, which is at least partially or completely covered with a topping rubber layer, where the topping rubber layer is made from the above rubber mixture; and (2) the rubber mixture comprising at least one diene rubber, at least one functionalized liquid polymer having the average molecular weight of 10000-100000 g/mol and at least one silicic acid and other additives.
