The fit between a wheel and a tire is improved. A tire assembly fitting device fits a bead portion of a tire of a tire assembly, including a wheel and the tire mounted on the wheel, to a bead seat portion of the wheel. The fitting device includes a support portion configured to support the tire assembly, and a pressing portion. The pressing portion is configured to press a first surface portion in a surface of at least one of sidewalls of the tire. The support portion is configured to support the tire assembly so that a second surface portion located in the surface of the sidewall on the opposite side of the rotation axis of the tire assembly from the first surface portion is displaceable in a direction away from the rim center plane of the wheel.

The present invention relates to a lubricating agent for mounting or releasing a tire bead, comprising alkaline electrolyzed water and a lubricant component. The lubricant component comprises a lubricant base oil, which is made up of a mineral oil and/or a synthetic oil, and a surfactant. The present invention relates to a method for producing a lubricating agent for mounting or releasing a tire bead, the method comprising: mixing an alkaline electrolyzed water with a lubricant component. A tire and wheel assembly method, comprising: applying the above lubricating agent onto a contact surface of the wheel with a tire bead, and thereafter assembling the tire onto the wheel having had the lubricating agent applied thereon. A method for dismantling a tire and wheel integrated together, comprising: causing the above lubricating agent to seep onto a part of a contact surface of a wheel and a tire bead, and thereafter releasing the tire from the wheel. The provided is a lubricating agent for mounting or releasing a tire bead allows mounting a tire easily onto a wheel, at a bead seating pressure of 300 kPa or less; leaves little residual component after mounting; and enables easy releasing of a tire from a wheel. The present invention provides a tire and wheel assembly method and dismantling method in which the lubricating agent for mounting or releasing tire beads is utilized.

The present disclosure discloses an air valve for a tire bead seater solves a problem that an inner piston in the air valve is prone to be difficult in moving upwards or downwards due to a thermal expansion and contraction of the piston and has a poor sealing performance when using a tire bead seater, and it is difficult to replace a barrel of the air valve with barrels in other different shapes to satisfy different inflation requirements. The air valve of a tire bead seater includes an inflation cylinder, where a top end of the inflation cylinder is provided with a cylinder mouth. In the present disclosure, through a cooperation between an upper sealing ring and a lower sealing ring that are made from PEEK material, it has a good temperature adaptability and a small deformation.
