The wheels will bolt on, since the bolt pattern is the same, however, the commercial chassis wheel is a heavier steel, and has steel rivets reinforcing the center web to the outer rim. Rims are similar to tires, as to the weight rating, and as such, they should be replaced with like kind and quality. Most of us install Extra Load rated tires on our vehicle, because of the weight of the vehicle. Just think of the wheel as an extra load wheel. A standard Cadillac wheel will fit, and a standard load tire will go on the rim, but will the rim or the tire fail under the weight of the vehicle. No one know for certain, but just like so many things in life, you take your chances, and the consequences of the decision you make you own. I wouldn't do it, nor would I advise anyone else to do it.
