Default DOT decoding Firestone Wide Oval

Hello,

I just bought a Corvette C3 1972 with Firestone Wide Oval tires.

I have searched the forum, but I canīt find out how to decode the DOT code.

Could you pls help decoding the DOT?

Tanks in advance!

I found something interesting in http://en.wikipedia.org/wiki/Tire#Markings

"For tires manufactured in the 1990s, there is a little triangle (Δ) after the DOT code"

I think there is a triangle: 200Δ -> 20th week of 1990 ??

OMG

I didn't see the triangle in the pic, so that is right if it is there. I will say that tire was repop'd by Coker tire.
