PROBLEM TO BE SOLVED: To provide a wheel having a counter balance with superior run-out accuracy. SOLUTION: The wheel 10 for automobile includesa disk 7 to be press-fitted to the inside of a rim trimming 8. The disk 7 includes four flanges 3a-3d and four disk material reductions 4a-4d. An air valve is fitted to a valve hole 9 of the rim 8. One disk material reduction is present at the position corresponding to the valve hole 9. The counter balance mass for the mass of the air valve can be easily ensured by setting the length of two flanges 3a, 3d for holding the disk material reduction on the opposing side of the disk material reduction to be larger than the length of the other two flanges 3b, 3c.
