Original tire care

[Nova Research Project]

Mark,

I think the aqua (or other color) line was on most tires. It was applied in the mold like the other lettering. Other than that I do not know what it signified. Any chance of emailing a picture of the code?
Thanks, Greg

Mark,
If by chance you have a build sheet, the tire code is listed in box 93. Those numbers/letters are stamped on the tire. If you have the sheet, check it against the stampings.

I've had a good many Nova's and have usually been able to find a build sheet, if I looked. You think it would be a sure-thing to find one in a 5000 mile car but no luck so far.

As we all know there are a few people out there trying to pass off their old big blocks cars as real 6cly cars. Good doucumentation is everything......

Dennis Cumby just forwarded a photo of an original spare out of his Nova to me. He stated there was no letters/numbers on the tread only a stripe so the build sheet code may not apply like it does to the Chevelles. In some cases, they were a different manufacturer and maybe the white wall vs raised white letter tires might have something to do with it.

NNN had a picture on a low mile car with an intact spare with KODB (I think) on the tread. This is the 70 broadcast copy code for the BF Goodrich Silvertown dual white stripe white walls. Different manufactures could have coded them differently. The broadcast copy has 4 spaces for tire code. Boxes 266-276 on the Chassis Broadcast. Greg

OK, I know this thread started about the care of original tires and we've deviated some but I'm going to display my total ignorance of this matter. When were the stamping/markings placed on the tires? Were these done at the tire manufacturer or were they applied at the assembly plants? If done at the manufacturer, were the specs supplied by GM and were they different markings for each supplier, i.e., Goodyear, Firestone, Uniroyal, General? A lot of questions, I know but this is getting interesting. Anal, but interesting!

Hi Dennis
I watched a 16mm 45 min. movie I found titled "1967 Chevrolet and Uniroyals".
It is a great feature film showing the Tires being made from scratch,then tested on Chevrolet cars.It looks like the codes (Like L8DS in my 70 application) were applied to the tread during tire assembly.The codes appear to be different,but it is hard to see them all in this fast moving movie.
I also have 12 B&W Polaroid pictures of tires taken during assembly in Oct 1966 at the Baltimore tire assembly plant.They clearly show the codes being applied during tire construction,then mouned on rims for shipping.
I am not a tire expert,but it looks like these tread tire codes were done by the tire manufacturers,then shipped to prospectve Assembly plants where they were put onto the cars.

I'll try to get a pic of it. It might not show up. Mark
