A sealant layer assembly which allows a sealant layer to be applied on a tire outside of tire production plants. The assembly comprises a sealant layer to be applied on the surface of an inner liner layer facing the inner cavity of a tire, a net layer arranged on a first surface of the sealant layer, and at least one non-stick protective layer arranged either on a second surface of the sealant layer opposite the first surface or on the net layer.

Sealant layer assembly

Disclosed herein are a sealant composition for use with tires, a tire having at least one component with at least one surface at least partially coated with the sealant composition, and related methods for applying the sealant composition to tires. The sealant composition comprises biorubber and a softener comprising at least one of plant oil or plant resin and has a non-petroleum content of at least 70% by weight.

Tire sealant composition

Pneumatic tyre () comprising a carcass ply (), two ring beads (), a tread strip (), a tread belt () comprising at least two tread plies (), an innerliner () and an additional functional material layer () arranged between the innerliner () and the inner cavity () of the pneumatic tyre (), wherein between the innerliner () and the layer of additional functional material () a net layer () is interposed, which facilitates the removal thereof during disposal at the end-of-life of the pneumatic tyre.

Pneumatic tyre with elements for the easy removal of additional layers

A method for reducing the stickiness on the surface exposed to the air of a sealant layer applied on an inner cavity of a tyre. The method establishes that the surface exposed to the air of the sealant layer is subject to a UV radiation.
