The Stovebolt Site Forums The Shop Area General Truck Talk Goodyear 7.50-17 Tires

I have a chance at getting some 7.50-17 Goodyear Tires,Standard Highway Tread.
What I am trying to figure out is the age according to the mold numbers.
First off they are still Brand New,Never mounted.
Made in Mexico.
The Markings/Panels on the sidewall read,
In the first oval,
7.50-17 NYLON
Capacidad 8 Capas
SIN CAMARA
Should be the Ply Rating?
Next Oval,
NPX7 LKOT 117
Birthday of the Tire?
Third oval,
What looks like a Flag/Banner on a pole over,
Tragaleguas G8
MEO3101-24 KP.
Ratings and inflation info?
Longbox 55, Anybody??
Thanks for any help.
