Thank you for detailed response. I have read many of your posts and find them all to be very informative. Yes, I intend to take my own measurements; will post here for reference. The impetus for new wheels is that I believe my dad installed 15” wheels with improper backspacing; still need to pull wheels off to confirm BS. The original tire diameter was 25.3”, so keeping a replacement near that or under 26” is a good bet?
