Abstract:
A method for determining an impressing depth of a tire on a motor vehicle disk wheel, the method comprising:arranging the disk wheel on a main shaft of a wheel balancing machine, the wheel balancing machine defining a reference plane; bearing a hub mounting surface of a disk portion of the disk wheel against an abutment surface that is fixed to the main shaft of the wheel balancing machine; measuring a distance from said abutment surface to said reference plane; measuring axial distances of outward and inward measuring points of a rim of said disk wheel from said reference plane; acertaining a width of said rim of the disk wheel; imputing said ascertained and measured distances and said width of the rim into a computer, and using the computer, determining the impressing depth with the values of said input distances and width in accordance with one of two formulae that follow: E=dâˆ’b/2âˆ’c; andE=d+b/2âˆ’a; whereinE=the impressing depth; d=the measured distance from the abutment surface to the reference plane of the wheel balancing machine; b=the width of the rim; a=the measured distance from the outward measuring point of the rim to the reference plane of the wheel balancing machine; and c=the measured distance from the inward measuring point of the rim to the reference plane of the wheel balancing machine.
