Wondering if this is an original spare from a 78 K5. It is the Firestone Deluxe Champion tire.

Original spare?

1st thing would double check the size. I can't see it in photos
And date code on tires
I doubt the tire is the original, it doesn't look 44 years oldWondering if this is an original spare from a 78 K5. It is the Firestone Deluxe Champion tire.
I don't know if a tire that age has a date code.
They do but before 2000 it was a different sequence

Code is on the rim by the valve stem hole as well as some of the information on the face or the wheel.
Format is:
K1y m (Valve Stem Hole) dd aa
where:
K = Kelsey-Hayes
1 = Romulus, MI wheel plant
y = calendar year
m = month
dd = day
aa = application code
So if I understand correctly the rim was made on 12/17/77 and is application code XU.
Here are the rim markings.

So if I understand correctly the rim was made on 12/77 and the tire was made in the third week of 1978. So this must be an original spare tire and rim for a 78 K5 Blazer. Rather cool.
I found this information also for reading the date codes on a pre 2000 year tire.

147 could be right for 78. The H78 15 is correct size tire for 78 k5
Pretty cool, hang it on the wall. Dont use as spare
I think my spare is from ‘87, will have to check. Will work to roll it up a flat bed, but wouldnt trust it for any road use.

I need the wheel rim. I'm going to mount a BFG KO2 tire on the rim and use it as a spare.
As for the original tire. I don't have the space for it. Maybe it has some value.
It is interesting that it takes about three months from when a rim is manufactured to when a new tire is installed at the factory. This is a west coast K5 so there would have been some shipping time to the Fremont factory from the Romulus, MI wheel plant.
