Goodyear tires

[9566 BA]

I bought some goodyear polyglass F 70-14 for my 69 chevelle and the person at Kelsey tires
indicated that any chevelle made before 12/69 the F 70 14 would not be in white letters, only Goodyear polyglass is and that after 12/69 has the tire size in white letters. I would like to know if anybody knows about this . Jeff

Yeah, when I ordered my Polyglass tires for my LS-6 they asked when it was built, and when I asked "why", they told me about the white letter thing. I told them, but I also told them I didn't really care, as I just needed the tires immediately (it was the week of the Pure Stock Drags!).

But, I still don't know any more about the white letter thing, but I would probably say that Brian does....

I think his dates are wrong.12/68 sounds better.
I haven't seen any 1968 Chevelles with white letter tires from the factory.They started putting white letter tires on Chevelles in 1969,so those early built cars might not have gotten them.
The 12/69 production date is heavily into the 1970 cars Production time and the Aug-Dec.cars have been documented with white letter tires by then.
The Brands available from the factory were: Goodyear,Goodrich,Firestone,General,and Uniroyal.Buildsheets did not specify tire brands.

The 68/69 Novas did not ever use white letter tires. I think the 70 Novas did not use lettered tires either? {Marlin?} Red stripe/white stripe and I have been told plain black sidewalls only. I do not believe that the 69 cars used the Goodyear Polyglas wording until very late 1969 if at all. Original cars using Goodyears always say Wide Tread F-70-14. Most original tire F-70-14 Camaros I have seen use the Uniyroyal Tiger Paws that are not reproduced. Any other opinions on the Polyglas tires is very welcome...BKH

BKH;
You are correct, Novas were not available with white letter tires, only redwalls (through '69) or whitewalls. Not sure regarding the blackwall, but wouldn't be surprised. This not what most Yenko guys want to hear, but it is what they came with. Check out the original pic of the Forest Green Yenko Nova under the 'Vintage Photos' section of this site.

I think the debate is getting off of Kelsey Tires' point. They're commenting on two types of white letter tires, Polyglas's with the size also in white letters, and those without. Initially they were done without, and changed to "sized" configuration early in the 1970 Model year. This became a big point to '70 Boss 429 show competitors, as all 499 of these cars were built prior to the end of calendar year '69 and were fitted with no-size F-60-15 Polyglas tires originally. Until recently, there were no reproductions of the "no size" Polyglas tires and original, perfect sets of five were selling for upwards of $5K. (Yikes).

Wide tread GT's were a simpler, cheaper tire with similar lettering to the Polyglas. I just found a couple of used original F70-14 Wide Tread GT's. Thanks bkhpah, now I know what they're for One probably needs to go in the trunk of our red '69 Chevelle L-78/M-22 car....

I went to a car show yesterday and there was a 69 ss chevelle that the guy had bought new and had given it to his son which was showing the car at this show. He had goodyear F70-14 widetrack tires on it. He had the original spare and the F70-14 was in white. He had brand new tires on the car and I asked him where he got them he couldnt remember but it wasnt Kelsey it was someone in Oklahoma that was repoing them. I went home and looked at my 69 chevelle adds that I have collected from old magazines and one it shows clearly "goodyear widetrack F70-14" all in white letters. The guy had the build sheet and the car was made in Atlanta on 3/31/69. Jeff

Well, this required some research before I shoot my mouth off some more. The initial discussion was for Polyglas GT's. Bear in mind that back in the day Goodyear produced the Wide Tread, Wide Tread GT, Polyglas, and Polyglas GT, all with that cool little lettering.

I, too, dug out my old archives and looked at the new car features from '69 to '70. Here's what I found (keep in mind the print lead times of a couple of months):
1.Hot Rod June '70: Goodyear Polyglas GT ad shows a '70 Boss 302 with F-60-15 Polyglas GT with no size, while the pretty girl standing next a loose tire off to the left has "Polyglas GT F-60-15" added by the art department to the face of her tire. My guess is Goodyear found that the size was a marketing advantage and added it to the GT design in Œ70.
2. Marty Schorr's CHEVROLET THE PERFORMANCE YEARS, a book compiled of Schorr's archives from his time at CARS Magazine. One picture shows their ZL-1 Camaro test car, wearing 15" Wide Tread GT's (no size). Another shows a black COPO owned by an employee of Greenwood's race shop in Troy, MI. It's wearing "Wide Tread F-70-14" (sized, non GT) tires on 14x7 Ralleys.
3. Car and Driver, Jan '70: Olds 442 ad wearing "Goodyear Polyglas G-70-14" (sized, non GT) Same issue has a 70 Cougar Eliminator ad wearing "Goodyear Polyglas" (no size, non-GT, 14").
4. CARS April '69, Baldwin Chevrolet's Ed Simonin's personal '69 RS Z/28 fitted with "Goodyear Wide Tread GT's" (no size).
5. Super Stock and DI, Oct '69: '70 Hemi Cuda with no size Polyglas GT's, '70 GTX with 14" no size Polyglas (non-GT), '70 Challenger 440 R/T with 14" no size Polyglas GT's, '70 Mach 1 with no size 14" Polyglas (non-GT), Buick GS455 with no size 15" Polyglas GT, '70 Chevelle 454LS6 with sized F-70-14 Polyglas (non-GT). These are all very early cars, and the LS6 was a preproduction "teaser" for the press about what was coming midyear.
6. CARS Nov Ã69: What is listed as a Phase III Motion Camaro, but looks for all the world like a Motion tweaked COPO (no SS badges, column shift auto) has Wide Tread F-70-14Ãs (sized, non-GT) on the front with big meats on the back. And perhaps most telling about availability in mid to late Ã69, a freshly built dune buggy with no size 15” Polyglas GTÃs on the back and sized Wide Tread F-70-14Ãs (non-GT) on the front.

To my mind, Goodyear began producing all of tires with no sizes in the print. The non-GT versions of the Wide Tread and Polyglas apparently started having the size on them sometime in early Ã69. The GT versions kept going without size. My guess is that marketing figured out that the public liked the sizes on the side and they switched the GT lines to sized configurations as well. I belive the Polyglas GT change occurred around Dec Ã69.

Fun, if somewhat arcane, thread here......
