A disclosed example embodiment of a gauge wheel tire includes a first polyurethane sidewall portion, a second polyurethane sidewall portion, a polyurethane ground-engaging portion, and a polyurethane axial support portion. The first polyurethane sidewall portion is spaced apart from the second polyurethane sidewall portion, and the polyurethane ground-engaging portion extends from the first polyurethane sidewall portion to the second polyurethane sidewall portion and is adapted to contact a ground surface as the gauge wheel tire rotates about an axis of rotation. The polyurethane axial support portion extends from the first polyurethane sidewall portion to the second polyurethane sidewall portion, and is spaced apart from the polyurethane ground-engaging portion to form a gap that allows radial movement of the polyurethane ground-engaging portion relative to the polyurethane axial support portion.

Provided is a resin-metal composite material that ensures high adhesion between a resin material and a metal material. Additionally provided is a tire that achieves high durability by using the resin-metal composite material. The resin-metal composite material includes a metal material and a resin material that coats at least a part of the surface of the metal material. The resin material includes, as a main component, a thermoplastic resin having a polar group. The surface of the metal material is treated with a buffer solution having a pH of from 5 to 7.2, and an abundance ratio of copper to a total amount of copper and zinc (Cu/(Cu+Zn)100) in the surface of the metal material is from 55 to 95% by mass. The tire includes a circular tire frame formed of a resin material and a reinforcing layer composed of a reinforcing member wound around an outer circumference of the tire frame, in which the reinforcing member includes the resin-metal composite material.

A tire dismantling method is provided that is capable of dismantling a reinforcing member from a tire in which a thermoplastic material and the reinforcing member are an integral unit. The dismantling method is of a tire including a tire frame member (17) formed of a thermoplastic resin, and a reinforcing member (26) laid up at a tire radial direction outside of the tire frame member (17) and formed of a material with a higher rigidity than the tire frame member (17). The tire dismantling method includes an opening-out process of cutting the tire along a width direction to make the tire into a belt shape, and a reinforcing member separation process of crushing the belt shaped tire to separate the tire frame member (17) and the reinforcing member (26).
