Needing new tires

Sounds good. I will have a shop pull the tire off when I'm ready to do this.

Of course now that we started talking about this, I located an 8.25 rear end with BBP. So I may delay the tires until I put 15s on the back. Thanks for your input. These technical things are beyond my experience still.

No reason to.
All 14" small bolt Chrysler Rallye wheels are 14"×5.5".
Your 225/70-14 tires are fine on them.
