Stupid basic Question: a spare temporary wheel to fit various B & E bodies

[70Challenger440]

I need a cheap spare wheel to use for the occasional flat or around my garage for multiple Mopars. Amazon has one I think would work but it does not give backspace. (AMZ specs are 15x6, 7mm positive-Offset, 5X114.3. Is that a 3.75" backspacing and the equivalent of 5x4.5" lugs?. I just want to put a basic 205/70r15 tire on it. (giving a  26 to 27in overall diameter)


I need this one spare  for temp use across 4 cars:
69 Charger RT 14" wheels (drums), 69 GTX 14" wheels (drums),
70 Challenger RT 15" wheels (drums), 70 AAR  Cuda 15" wheels (front discs).

The  wheel is here: https://www.amazon.com/gp/product/B01MQ18WE6/ref=ask_ql_qh_dp_hza ($78 free shipping)


Will this fit and be ok when temporarily needed on all these 4 cars? (with it's 3.75" backspacing)

I think the center hub bore is not big enough for Mopars on this rim in your link.

Chrysler: 2-13/16"
Ford: 2-3/4" (for the ones with a center hole that almost fits on a Chrysler, but not quite)

For the folks who are fond of the French units, that translates to:

Chrysler: 71.4375 mm
Ford: 69.85 mm

I ran into this when I used the modern Ford aluminum space saver spare, I had to machine out the hub bore slightly to fit the Challenger.

Brads70.... With your info I came across this
https://www.summitracing.com/parts/vsw-55-5604  ($64)

15"x6"... 5x4.5" ... 4" backspace ... 3.22 center bore (i assume a larger center hole is ok?)

They seem to be ok regarding all the specs even the center hole I didn't even think about until you brought it up. However when you plug them into their fitment guide it says not compatible. I was thinking maybe the issue is their guide. Will this rim work for my spare?

When I apply a 70 Challenger in summits search feature it says it will work. Backspace seems like it should be a little less but I guess it will work. If it were me I'd search at a swap meet and find a used Mopar ralley rim , the rim you linked looks like a chevy rim to me but thats just my

I purchased one like you show on ebay.  I was able to use a die grinder and a flap wheel to open up the ID 1/16".

For my 74 Challenger, it has 14" wheels so its height is about 25.1 inches.  I went to the local U-pull-it and bought a Doughnut wheel/tire from an older Chrysler mini van.     Its a 15" doughnut that fits just fine and being 15" its height is about 25" also with the doughnut on it.  I think i paid $25 bucks for it, and being a doughnut it fits way better in the trunk than a full size tire.    I also bought the scissors jack that is used on those vans for $12.   The combo works fine.   

About two weeks ago I had a flat on my Challenger (maybe the first flat i've had on any car in about 5 years) and put it on.   Drove it home and no problems.
