tire writing on Camaro

[T Billigen]

Does anyone out there have a new NOS E70/15 wide tread GT that has the writing on the tread of the tire? Or does someone have a build sheet with the tire code on it? (1969 Camaro) Thanks

Here is a very fresh 1968 Wide-Tred.This is on a survivor Z-28 that was removed for judging....I doubt it was ever out for any reason other than this.FYI, the rim is black, this was a car from the Proving Grounds in Mich and used as an Executive car/test car until circa 1971..This car has some very interesting stuff on it and a great history!

I'm a doubter that a test vehicle would have a factory spare in it after 3 years of use. The garage would rotate them. That tire is a vintage replacement, possibly right before they sold the car. And the rim shouldn't be black unless all the rims were black.

I've never seen an original first gen spare with a code on it, and there wasn't a broadcast code for first gen tires.
What do the judging standards or Brian / Jerry say?

All the rims were/are black.This car is a rare car to look at.There are a lot of differences from the norm.I am most certain the spare is correct for this car.The orig front and rear tires are still with the car.The fronts are still in use.Here is another interesting shot......anyone ever see this??

I did give the exception that all wheels could be black. /ubbthreads/images/graemlins/smile.gif
Driven inside GM for 3 years and still has all 5 original tires?

Bill G came up with the following pic out of the July 68 Car Life road test. Thanks Bill!!!

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.

[Unreal]

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

[Kurt S]

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."

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.

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. /ubbthreads/images/graemlins/beers.gif

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

[Kurt S]

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 /ubbthreads/images/graemlins/dunno.gif

Oh yeah,the 68 Z didn't have the "shot" either.It had the dot on the tire though.I have noticed more marks on the Uniroyal tires and Wide-Treds but very little on anything else.Here's another on a 69 Low Mi SS.....

I have an original E70x15 wide tread GT out of a 68Z28 that has the same E 75F01 stamped on the tread, it has the right code on the rim for a 68Z.

[T Billigen]

Kurt, did you get the pics I sent of the 1500 mile Z-28? /ubbthreads/images/graemlins/dunno.gif

[Kurt S]

There are a couple of service bulletins that discusses the tire balance issue and matching the tire to the rim via the dots.

Thanks Tom. Fits everything we've seen, appears to be the supplier's internal coding. Which means every tire make would be different.......

Really nice Z, same colors as mine. Too bad someone added the style trim...
