I remember reading many years back, using the mbody and maybe jeep donut spares work on the old mopars.
What is a good one today I might find in the yards?
While it says the modern mopar are the same bolt patter, I recall reading they were off by a bit. like 115 mm vs 114.3 or something.
I found wheel bolt pattern look ups, but nothing tells me what the center hole is. The couple I tried were way too small to get over the disc brake hub.

2003 Cadillac CTS compact spare works. It's a light aluminum rim and it fits in an A-body spare tire well. I'm not sure what all years will work, but the junk yard should know.

ah, sorry, that must fit the small bolt pattern.
I was looking for the regular size 4.5 x 5.

the center registry hole on caravan 15 & 16" doughnut spares are the same as the early wheels, which is 2.810-2.820 until at least 2007. they are the same 115mm bolt center as well.

thanks. so that confirms it for me 115 vs 114.3
so it is off by a bit. but for a spare I guess I won't worry.
Thanks. gives me a starting place.

I got one out of a Crown Victoria, fits my 70 Charger. I read all that in a long lost Mopar mag.

The Cadillac CTS spare is a 4.5" (Big) bolt pattern.

isn't the crown vic an aluminum wheel ?
i remember years ago, there was a 15x 4 or 4 1/2" wide spare in a couple of ford products that was aluminum.
i "think" you also had to open up the register hole a bit ?
i have only seen a couple of those floating around over the years. all at different times, or i would have bought a pair just because.
