METHOD FOR FORMING A SEALANT LAYER IN A TIRE

A method for forming a sealant layer in a tire is described, wherein the tire produced is balanced. The method comprising the steps of: providing a tire; and spraying a sealant layer on the inside of the tire, under the crown, wherein the sealant layer is sprayed at a zero degree angle with respect to the tire mid-circumferential plane as the tire is rotated.

Tire sealant composition

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 Casing and Wheel Assembly Comprising an Enhanced Self-Sealing Product

An assembly of a pneumatic tire and of a wheel, the pneumatic tire (10) being fitted to the wheel. The assembly comprises first and second self-sealing products housed in the internal volume (V) of the pneumatic tire (10). The first self-sealing product, referred to as solid self-sealing product (OS), covers a predetermined part of the internal surface of the pneumatic tire (10). The relative position of this predetermined part in the pneumatic tire (10) does not substantially vary under the effect of gravity. The second self-sealing product, referred to as liquid self-sealing product (OL), is in the liquid form.

Pneumatic vehicle tire

The invention relates to a pneumatic vehicle tyre with a sound-absorbing inner absorber (9) adhesively attached in its interior to the inner surface (7) opposite from the tread (1), wherein the inner absorber (9) adheres to an automatically sealing sealant (8), which at least immediately after being applied has the tackiness required for the adhesive attachment. In order not to influence the flow properties of the sealant disadvantageously and in order to ensure a reliable sealing effect of the sealant, a separating layer (10) is arranged between the sealant (8) and the inner absorber (9) and the separating layer (10) is made in such a way as to ensure a sufficient flowability of the sealant (8) for the sealing and a reliable adhesive attachment of the foam ring (9).

Flat tire repair liquid container

Provided is a flat tire repair liquid container including: a container main body including a container body in which a flat tire repair liquid is stored, and an opening; and a cap including a flow path configured to guide the flat tire repair liquid out of the container. The flow path includes a cylinder portion of which an end of a first side is open toward internal space of the container body and in which a closing plug is slidably inserted, and a dispensing portion branching from the cylinder portion and open to outside the container. The closing plug is configured to close the flow path by being positioned at the end of the first side of the cylinder portion, and to open the flow path by being subjected to pressure inside the container during flat tire repair work and moving to a second side.

Pneumatic tire having sealant layer

A tire with a built-in puncture sealant comprising a supporting tire carcass comprised of one or more layers of ply, an outer circumferential tread, and a radially inner layer, a pair of beads, sidewalls extending radially inward from the axial outer edges of the tread portion to join the respective beads, a sealant comprising a butyl ionomer containing degradation product, disposed inwardly from said tire carcass inner layer, wherein said sealant provides self-sealing properties to the tire.

MOTOR VEHICLE COMPRISING A COMPRESSOR ASSEMBLY

A motor vehicle with a compressor assembly for the supply of a pressure medium to a tire cavity of a tire of a motor vehicle. The compressor assembly has a compression chamber which is rotationally fixed in relation to the motor vehicle wheel, and the compression chamber and the tire cavity are connected via a fluidic connection for the conveying of a pressure medium from the compression chamber into the tire cavity. A tire sealing device has a sealant reservoir with a first connection fluidically connected to a tire cavity of a tire of the motor vehicle to be repaired, and a second connection fluidically connected to a pressure medium source secured to the motor vehicle. The sealant is conveyed out of the pressure medium source into the tire cavity of the tire to be repaired by means of the pressure medium.
