I was reading an article on Hemmings online about car ads in the '60s and '70s. The mentioned the Dr. Oldsmobile ad with the yellow W-30. One of the things they said about the ad (they really liked it) was to try to read the lettering on the tire. I've never paid much attention to that, and I can't find a large enough resolution image on the internet to blow it up enough to be able to read it. Has anyone actually read the lettering on the tire, and if so, what does it say?

 

All I can see on my full size copy is OOD YEA and POLYGLA and G. Anything after the G is hidden inside the wheelwell.
