Hot Rods Ribbed Goodyear tires!!??

I purchased a 46 business coupe about a year ago and these cool old ribbed white wall tires came with it. Anybody know what year they were produced?

 

WOW. Very interesting. I'm no help with the mfg, but the concentric rings kinda reminds me of the Warner Bros. cartoon ending... that's all folks! Gary

 

There should be a date code somewhere on them.

 

Coker repop's these. Are they double white walls as well? If so, be prepared to dig deep into your wallet.

 

The same tires came on my 48 fleetmaster when I bought it. They are cool!
