tire writing on Camaro

I guess about a year ago ther was an original spare tire from a early 1969 Z-28 for sale on e-bay. It had all the writing on the tread and it had the early coded ralley wheel.

yeah, and it sold for over $800, as I recall!

Didn't see that one on ebay. Sounds interesting.

Here's what JohnZ says:

Tires didn't have any codes, stickers, or labels on them at all - only the inspection markings (colored lines, like pinstripes, on the tread, which pretty much disappeared during the roll-test/toe-in process).

Those are tire manufacturer internal ID codes - for their in-process tracking; didn't mean anything to the assembly plant; there were other smaller pad-stamped codes and markings as well on the sidewalls, usually near the bead, that were internal inspection marks too.

I think Frank Diharte bought the Ebay Tire. I also sold to a Board Member a orig. Sports Car 200 Spare Tire that still had stenciling on the tread.

The orange/red dot on the side wall (see earlier photo) is a low run-out spot on the tire marked by the manufacture.This is to be lined up with the high run-out spot on the rim,noted by a shot welded to the outer rim lip.This was incorporated into production at Norwood,Flint,and Willow Run when the tire was mounted.This is directly from a Dealer service info Bulletin 68-I-5 dated Dec.6 1967.There goal was "...to improve vehicle ride by minimizing tire and wheel run-out variations."

Just checked the original spare on my 69 Nova L78. The uniroyal tiger paw red line E70-14 has the red spot near the bead. However could not find the shot weld on the side of the 3 tab XT wheel. [img]/ubbthreads/images/graemlins/beers.gif[/img]

This probably does not matter much for Camaro's but the Nova had a four letter code on the tread of the spare tire that matched the tire code on the chassis broadcast sheet. There are some examples in the Nova Times of both the tire code (Feb 97 I believe) and a chassis broadcast sheet (Feb 93 and May 94 I believe). There also a picture of the red dot.

KODF was the E78-14 Belted White stripe
KODB was another code.

This was typical on 1970 & up A-Bodies (Chevelles).I think the tire plants started to use these codes for most cars around then.

Mighta started in 70 for F-bodies, but no broadcast codes on 67-9 Camaro tires.

Remember, it was plant specific according to the bulletin.It was also based on supply of each,tire & rim ,at the mentioned plants.Here is a shot of my "shot" on a 68 FC rim......I added the dot,I was unable to find it on my 68 Speedway Wide-Treds.......age I guess [img]/ubbthreads/images/graemlins/dunno.gif[/img]
