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. |
