Claims

[Scope of utility model registration request]

An automotive vehicle comprising a pneumatic tire, a rim that is divided in the axial direction of the tire and assembled to the pneumatic tire, and a load support that supports the load in the event of a puncture and presses the bead of the pneumatic tire against the rim. In the wheel, an engaging part in which a load support is formed inside and engages with a rim to restrain circumferential movement of the load support, and an axial side part that presses a bead part against a flange part of the rim. 1. An automobile wheel characterized in that the outer diameter of the load support body is equal to the outer diameter of the flange portion plus two to three times the cross-sectional thickness of the bead portion in contact with the flange portion.
