One the images that Marshall shared is a label in his trunk for Tyrex cord. I did some research on this and it is interesting. This label is for rayon cords in tires. The Goodyear Blue Streak tires came with nylon cords.

Seems there was a battle going on between makers of rayon cords versus those making nylon ones. Goodyear used both kings but the nylon corded tires were their premium offering over rayon.

Here's an article from 1961 covering this battle. https://content.time.com/time/subscriber/article/0,33009,894541,00.html

I could not find any tire manufacturer ad mentioning Tyrex but there are lots of standalone Tyrex ads with several implying that nylon cords were actually unsafe.

A mystery why his car has this label in the trunk. Anyone else have one?

More information on Captive Air tires.

I have two sets of these tires. This is how they compare:

All are Good Year
All are 900/14.
All have the reference on the back about inflation procedure.

From there differences appear:

One set is labeled Blue Streak, the other Double Eagle
Tread pattern is dramatically different.
Whitewall dimensions and style are different.
Overall tire dimensions are different.

Blue Streak Double Eagle
Standing height 29" 27.5"
Cross section 10" 9"
Whitewall at wheel 2.125"W .5" off wheel & 1.625"W

Six of these tires are still mounted. No liners in the unmounted.
I have made no attempt to find liners in those still mounted.

I have no placards or labels for their warranty or use.

Both E & F have all trunk tools and jacking instructions in place.
F has an additional small label indicating the tires have Tyrex Cord.

E Owners Guide explains inflation procedure for Captive Air tires.
1960 Chrysler manual shows Captive Air tires are available on wagons.
F supplement manual shows:
"Your Chrysler 300F is equipped with Special Good Year Blue Streak racing type tires."
