Answer: Massey-Ferguson front tire lug nuts typically come in 1/2 inch to 3/4 inch sizes, depending on the make and model of the tractor, as well as the type of rim or wheel being used on the tractor. The size of the lug nuts is often inscribed onto the face of each lug nut. In addition, you may need to consult the owner’s manual for the correct size. Generally, most common sizes are 6-point, 7-point, and 8-point lug nuts, measuring approximately 1/2 inch to 3/4 inch in diameter.
