PROBLEM TO BE SOLVED: To provide a vehicular wheel capable of knowing the damage to an air chamber by easily discriminating the presence/absence of input to the air chamber during vehicle traveling, and preventing the breakage of a wheel tire due to the damage to the air chamber. SOLUTION: Coating (crayon) is applied on an upper surface of the air chamber 12. In large input with which a tire 14 reaches the air chamber 12 during traveling of the vehicle, the tire 14 contacts with the air chamber 12 on a rim 11, and the coating (the crayon) applied on the surface of the air chamber 12 is transferred to an inner surface of the tire 14. When the tire is exchanged, it is inspected whether the coating (the crayon) transferred on the inner surface of the tire 14 exist or not, or whether peeling of the coating (the crayon) is generated on the upper surface of the air chamber 12 or not, thereby discriminating whether input to the air chamber 12 is carried out or not during traveling.
