A spare wheel might be harder to source than you think!

@2manytoyz, most of the problem is it appears you don’t know what wheel it is and what fits.
If a 16” doesn’t fit then it’s a 17” rim which is standard on all the dually trucks for the last 15 years or so.
I promise whatever you have if it came off the Ford line is not rare.
Start by figuring out what size the wheel is.
