Goodyear Polyglas tire date code - 05/28/13 05:36 PM
What does this date work out to? I'm pretty sure it is the original G60-15 spare tire to my car.

BA = (date) 31st week 1970 (~8/2/70)
NB = (plant) Goodyear Akron II, OH tire palnt
JC = (size) G60-15
DL = (type) fiberglass belted w/RWL
Sounds like a good fit.

I've got a totally different code on my original Goodyear spare tire. I think I've decoded some of it
JE91634 - Serial number
J – 1969
E – Nov
9 - ?
1 – Akron Plant
634 – sequence number
Anyone know what the 9 means?

Thanks Dan! It has never been on the ground and was still on the 450 steel wheel until this past November (guy put a new BFG on it).

What size is it F70-14 or F60-15? White stripe, RWL with size, RWL w/o size? Got pics?
I believe the last 3 digits are G34.
I believe that Goodyear used "01" & "91" to distinguish between plants I & II in Akron, OH before 1970. In '70 it was "NK" (and later ""MA") for plant I vs. "NB" (and later "MB") for plant II.
In 1970 they went to the format on James' tire. Calendar year 1971 DOT mandated a standardized coding for all tire manufacturers.

It is a F60-15 RWL. You are right - it is G34

You must have other charts because I couldn't make sense out of 2 shown 
Now if I only knew what it came on.
Thanks Dan

It's a '72 Corvette tire (if they got them from Topeka, if not it's real close).
Posted By: 52savoy
Re: Goodyear Polyglas tire date code - 06/02/13 05:50 PM
I thought it might be..
Couldn't it be for an earlier Corvette also. Maybe a replacement tire from a Goodyear store in 1971?

Is there any charts for a firestone wide oval?

Re: Goodyear Polyglas tire date code - 06/03/13 06:07 AM
Firestone had some type of system but I've seen NO "decode" material before the '71 calendar year DOT standardization.
What do you have? I've been collecting data to see if there is a way to reverse engineer any info from it.

Yes, Corvette started using that tire - nylon/F70-15 (Firestone & Uniroyal also) for the '68 model year (RWL in '69).

This post has explained the plant and date for Goodyear tires well. What is missing is a chart of codes for the size and type of tire. If someone has such a chart, would you mind adding it to this post? Thanks.

..... but I'd need numerous examples to prove the "educated guesses" - one tire I've been looking for proof of is a Firestone Wide Oval pre-1970 that is fiberglass-belted.

Sure we like pics, but what kind of car, what assembly plant, & size/style of tire?
Also, got pics of the date on the wheel?
