Will these tuck

Those were 16's

16 by what?

Pretty sure 16x7. This was years ago. Cant be for sure. I went to a junk yard and found 4 matching 6 lug chevy steelies and had them sandblasted and painted.

A 15x6 or 15x7 smoothie with probably fit then

Yes, you can find wheels to fit, as I said, I verified the biggest that will tuck is a 8" +25

Use an online wheel offset calculator to find out what matches that.
