Rubber Tire and Rim Question

I would like to get a 'spare' tire for my 2021 Ford Escape AWD.
Ford does not offer a donut tire as an option. Edit: well maybe they do.
Which means I would need to get a full size tire & rim / I'm ok with that.

My 2021 came with 225/65R17 tires (installed 2020 thru 2021).
The junkyard I called had no 2021 (or 2020) Escapes.
But did have a 2019 which comes with 235/55R17 (installed 2013 thru 2019).
The width difference is 10mm (.393")

I will check the center hole diameter and lug pattern, if all looks good then-
Question: Can you put a 225mm wide tire on a (steel) rim that had a 235mm tire on it ?
My concern is the bead area getting a good seal with no added stress to the tire.

I stopped at a Tire Shop and was told, "it would be fine"

So, ok to buy ?
Or should I call more junkyards and get the specific year (2020 or 2021) ?

Thanks for any suggestions.

235/55/17 tire has 4.6% smaller diameter compared to 225/65/17. For most AWD systems this would be a problem, but I'm not sure about the particular AWD system in your Escape. The vehicle will handle weird anyway. Personally, I would get the correct size tire.

Also, 235/55/17 tire has lower load index than what came from the factory, so that's another no no.

no,no
My 'new' spare tire would be exactly as what's on Escape now, the 225/65R17 / I'm paranoid about the diameter because of the AWD
But the junkyard Rim originally had a 235mm tire on it.

So my question is: Can you take a 235/55R17 tire off a rim and install a 225/65R17 tire on it ?

Where exactly will you store a full size spare. I doubt it will fit in the back under the floor. At least not without raising the floor 4 plus inches.
I would take it along on long trips (50+ miles) or driving downtown.
Also for rotating the tires (then I won't need two jacks).

I believe the best way to find a slow leak is regularly checking your tire pressure while in the driveway.

I meant where physically will you place it in the vehicle? Just plunk it down in the cargo area?

Your rim will be listed as a 7.5(ish)x17, the 7.5 inches are the width.

Tires come with a chart of rim sizes they do okay on, and the spread is typically an inch and a half, with the OE rims falling somewhere in the middle.

You can look up rims on car-part.com across the years to get the specs yourself.
