It was very common to use Ford 16" wheels on GM products. Ford wheels have a little larger bore so GM wheels will not work on Ford. However they are stud piloted so it doesn't make any difference. The trailer wheels were patterned after the Ford wheels and Ford hub caps fit. If you call the trailer wheel manufacturer, they will tell you they were not designed for a truck. However, all I can say is that a lot of them are used on trucks. I use the wheels on 7,000 trailer axles that were designed for 3,500 per tire at 80 psi.Trailer tandems put a lot of side pressure on wheel, trailers have brakes and run just as fast as the truck. So I will let you make up your own mind about using them.
