Cracked or broken plate

Flanges are defective if they have chips that are 1.5 inches long or longer or .5 inch

wide or wider.

If the chips are broken from uniform curling over the outer edge of the rim around the

entire wheel, the flange is not considered a defect.

Thin rims of 3/4 inch or less.

Shelling or spalling 3/4 inch in length and in width or larger. Built-up metal on the

wheel 1/8 inch or higher than the wheel tread.

Grooved tread 1/8 inch or deeper.

Thermal cracks: transverse cracks in tread, flange or plate of any length. Brake shoe

heating frequently produces a fine network of superficial lines or checks running in all

directions on the surface of the wheel tread. This is sometimes associated with small

skid burns and should not be confused with true thermal cracking and is not a cause

for wheel removal.

Cracked or broken plate.

Holes in plate: drilled, burned with torch or electric arc.

Scrape, dent, or gouge anywhere in the wheel surface more than 1/8 inch deep.

Slid flat spots 2 inches or more in length, or 2 or more 1 1/2 inches or more in length.

Mate to any wheel changed because of flat spot, i.e., replace wheels in pairs.

A wheel on the car showing evidence of being loose, such as oil seepage on the back

hub or back plate.

A wheel on the car shows signs of having been overheated and is evidenced by a

reddish brown discoloration, to a substantially equal extent of both the front and the

back face of the rim, that extends on either face more than 4 inches into the plate area

measured from the inner edge of the front or back face of the rim.

A wheel on the car has been welded unless the car is being moved for repair and has

been approved for such movement.
