I didn't use to carry a spare that fit my teardrop since it had easy to get 14" tires. I've since gone to the correct 600x16 tires so I had to find a spare that would work. Problem with my teardrop is that the suspension fits inside the wheel and it requires a 16" wheel to clear. The old 14" mags had wheel adapters which spaced the wheel far enough from the suspension to fit.
What I found is a Ford 16" aluminum temporary spare tire. Very light weight and my car and trailer have the same bolt pattern so I could use it on either. I just had to enlarge the hub hole in the spare to make it fit. The spare came in handy when I had a flat on my car on the way back from Pismo this year. The spare in my wagon is the original from 1964 and is buried under the third seat. I would have had to unpack the car to get to it.
There are compact spares available in several bolt patterns. I don't know what other makes use aluminum ones but Ford has several different ones in 4 and 5 bolt patterns. The one I got happens to be hard to find as it only came on cars with a special handling package. I've been looking for another one.
Nick.
