I am trying to find correct looking day one tires.
My spare tire is a goodyear H78-15 polyglas Custom Power Cushion.
I'm pretty sure I took this out of the trunk for the first time.
It has a factory doodle in yellow that is a 24.

Can anyone confirm this is an original tire that would have been on my 71 newport custom.
Would the spare tire have been a smaller size tire or equal size tire to the 4 on the road?

Would like to see some pictures that are day one with the tires visible.

The dual stripe white wall was a Mopar option fixture for many years, at least as far back as '64 on the then nylon tires. Mopar spares of that era were always the same size as whatever tires were on the rest of the car. Spare wheel was usually black instead of car color. Tread pattern on the tire in the photo is period correct, as is the tire size. Probably the factory spare.

Highly likely that's original spare, see cut from 1971 brochure. Wouldn't expect it to be worth a fortune but it is a nice curiosity. Radials are so much nicer, a single stripe whitewall would work well. My '68 Imp had the original spare, it was a triple stripe Goodyear, try finding one of those. My '70 RR has a rare early style RWL 60 series, that might be worth a few bucks.

Here is the original spare from Poppy, my 1970 Polara 'vert. Original vinyl mat, too.

That picture was taken in March 2018, a few days after I bought her from the second owner in PA -- she had 31,208 miles at the time and had been sitting since 1985 (last started in 1986). The tire is now in safe storage at home, replaced in the car by a new tire (if I get a flat, no way I am driving on the OEM tire).

I’ve got the original triple stripe in my silver ‘67, even used it and the bumper Jack once when I lost the tread on one of the tires that were on it when I bought it.
 
The dual white stripe was the standard w.w. in 70 & 71 as I recall.
Imperials had a variety of dual and triple stripe ww.s over the years but not that common dual stripe you show.

I'm not looking for any value in the original spare. Really just trying to find what looks the most correct on the market so I can replace my crappy tires with period correct looking tires. But I want to drive the car so I'm afraid of the bias ply tires since I just have no experience with them.

Interesting that the big brown C there doesn't have a double white wall, It has what looks like the wide 1" WW.
 
wow! triple white wall. And the tire has a factory doodle of 56. Pretty cool!

Actually, that's not a bias ply tire.

It's a bias belted tire. Still not a radial, but heads above in performance over a bias ply.

A pic saved off ebay, but similar to the original spare that came with my car, that I threw away.

A silvertown belted G78-15
Entirely different line of tires.
Would this "belted" tire have been basically the same as the polyglas tire?
Different manufacturer and year of course.

Firestone built some steel-belted bias-ply tires, but almost all of the belted-bias-ply tires used a fiberglass belt. Which in Goodyear-speak means "PolyGlas". By that time, almost all of the bias-ply tires were using polyester cord materials for the best compromise of strength and comfort. Hence, too, "PolyGlas".
