PROBLEM TO BE SOLVED: To provide a vehicular wheel capable of reducing rolling friction by raising tire temperature with a simple structure. SOLUTION: The whole outer peripheral surface 11d of a rim 11 is formed with an undercoat layer 13 of clear coating 5-40μm thick. Further, a bead sheet part 11a and a rim flange part 11b which a bead part 21a of a tire 20 adheres to (adhesion parts) are masked. The whole outer peripheral surface 11d except the adhesion parts is provided with heat shielding and insulating coating 50-500μm thick thereon to form a heat shielding/insulating layer 14. The heat shielding/insulating layer 14, for suppressing heat transmission from air in a tire air chamber MC and an inner surface of the tire 20 to the rim 11 in the outer peripheral surface 11d of the rim 11 which contacts air in the tire air chamber MC, is preferably excellent in reflexivity to heat radiation from those, heat insulation, and long wave radiation property for radiating the transmitted heat in long waves such as infrared rays and or far infrared rays while having high heat insulation properties.
