Application for these Goodyear Polyglas 14 x 7 F70-14
 

Changing these tires out on a customers 1970 Chevelle SS, which the last owner ordered the incorrect tires.
Wondering what the correct application (Cars) wore these Goodyear Polyglas 14 x 7 F70-14 Tires without the call out of the size.
Found A photo of what looks to be a 69 Camaro?
But Obviously not correct for 70 Chevelle SS.

Let me know your thoughts & Thanks in Advance.
I'll be taking these off soon but want to know for sure the application before I sell in the Classifieds here. Tires have less then 100 miles on them.

*Kelsey Only states these are for 1967 to October 1969*
Last photo is from the Kelsey Web Site.

I have some old pictures of our 69 W-30 442 and it appears to show the Goodyear Polyglas F70-14 ... the size may be a question as the picture is very grainy. I can attempt to post a picture if necessary. TAZ

Awesome work guys,
How about a 1969 Nova? Did they have these?

Sure Please post as I may save these for Ryan's Olds

Those are sexy tires but I need to focus on getting white stripes on the steel wheels with dog dish caps.

Ryan

Thanks Danny, these would be killer on my 1969 specific SS11’s!!! Someday.

OK -- let me see if I can make this work ...

Thanks for the photo but not relevant if knowing if those tires are original as it is clear those are custom rims on your Olds.

No problem at all Ryan, I still have to take them off in a few weeks and sell them in the classifieds here and re-new my membership here too. Rough last month with Kidney Stone attacks and now that I am better very busy catching up with all my 1970 Chevelle clients etc...

Thank you guys for all the Info so far.

Yup -- wheels came from my wife's uncle ... tires are the original that were on the Olds wheels. Picture was taken in Feb of 70 as border indicates ... Craig

When did you get this W30? Late in the year?

Ryan

Ordered the car in Vietnam and it was delivered to Bob White Olds in Green Bay, Wi. in January. My wife and brother had it "broke in" pretty good when I returned stateside in February 69'. Craig :flag::flag:

No. Chevrolet didn't use Polyglas in 69. There is a memo mentioning them later in the year and someone claims to have a orig. spare but overall the answer is no.

69 Nova...
 

As mentioned...there were no raised white letter tire options for the 69 Nova. The Nova SS came std. with E-70 x 14 red-line wide-ovals...white-lines were optional.

-wilma

One of those oddities: The Nova SS gets redline tires for 1968 and 1969. Then in 1970/1971 - whitewalls only. Finally in 1972 RWL tires become an option on the Nova SS.

Hi. I know my 69 Copo came with F70x14 Uniroyal whitewall tires when I bought it new. I tried to get the dealership to switch wheels and tires with the blue copo that was sitting beside mine as it had white lettered tires and rally wheels; they declined. I have always thought they were Goodyear Polyglass GT tires; is this incorrect? My 69 SS Chevelle documentation from GM says it came with white lettered tires so what would the correct tire be. Doug

Goodyear Wide Tread F70-14 RWL

427 Strato...They would have like the tires on the Chevelle above. Notice it does not say Polyglas.

Hi guys. Thanks very much for the information. I see that Summit appears to sell reproductions. Thanks again, Doug.

WTH, I bought my tires from Coker back in about 2004 and the guy on the phone was adamant that my car would have come with Goodyear Polyglas, so that what I bought.
It has IF wheels (same as buildsheet). I wanted to order wide treads.
Anyways what would have been on an early 11B Van Nuys car? Same as the Chevelle above?? Well if so, thats what I wanted.

----Jonesey,,,, I don't understand. Someone selling you something over the phone lied to you??? What? Had to do it. Sorry!.....Bill S

Early 70 roadrunner maybe? I was told the early ones didn't have the size in white letters on them, later cars did.

Ya Bill I hear ya. :haha: Maybe they needed to move that type of tire. I actually like the look of the wide treads better.

The Polyglas no size versions had been available from the middle of '68 when the Cobra Jet Mustangs came onto the market. The Polyglas tire also showed up in '68 on the Hurst/Olds that year (G70-14 white stripes)..

The elevated size version of the Polyglas started to show up in October of '69. It was a rolling change as they could not supply molds to all of the plants at the same time. By the end of December all of the tires on the new cars were the elevated size.

The Speedway Wide Tread is correct tire for the Chevelle and Camaro in '69, same as in '68. Pontiac, Oldsmobile, Buick had all moved their orders for Goodyear to Polyglas. Ford was wearing Polyglas for their performance tire. Mopar was wearing Polyglas as well. AMC too.

As Speedway Wide Treads being used to the end of '69.... We have some information available that the Polyglas was available on the Chevy order sheets for Chevelle and Camaro from 2nd quarter '69. There have also been one owner cars that have been documented wearing Polyglas from the factory. I do not have a single piece of paper showing the change but as stated, all of the other car makers were using Polyglas. That means that the ONLY two car lines using F70-14 Speedway Wide Treads were Chevelle and Camaro. I believe that it was Goodyear making the decision to stop making the F70-14 Speedway Wide Tread and move production to Polyglas. I do not mean to upset anyone, but I believe that enough evidence is out there to support the Polyglas usage from the April '69 timeline moving forward.

If anyone has documents to prove this otherwise, I would love to see these. If anyone wants to discuss this, please feel free to call me. Again, I am happy to help and sell want you want to put on your car. My cell is 816-654-3400.

For Mopar:

For 1969 only the Road Runner and Super Bee Spring Specials had the option of RWL FGB tires. You could get either Redline or WSW FGB tires as an option in 1969 though. Hemi cars came standard with FGB tires (15" Redline with WSW a NC option) as did the A12 440+6 Road Runner and Super Bee (G70x15 FGB Redlines only).

Mopar started offerring RWL FGB tires as standard and optional tires on 1970 models.

Are you saying you have documented one owner Chevys with Polyglas ?

I have some pictures that should help add clarity to this subject!

Rusty please post those photos and great Info. Thanks

The picture attached is a GM form from April of '69. Note tire option PL4.... Fiberglass belted RWL. Crap... failure to launch!!

Lets try this!!!!

The following sequence of pictures are from an original owner '69 SS 396 Camaro built the 3rd week of April '69.

The YJ rim is dated March 22, 1969.

Tire manufactured April of 69 at the Gadsten, OH plant

So now after 40+ years of Camaro collecting I have seen one Polyglas tire that apparently came on a 69 SS Camaro. Are there more ? I think they made about 34000 SS Camaro's, plus the Chevelles, Corvettes etc. Based on examples I would not recommend someone restoring a 69 Camaro SS use a Polyglas because I think the odds of it coming from the factory that way are very very very very slim.

Hate to admit this, but I tend to agree with Charley on this :CharleySucks:
Steve it's Gadsden AL. Not OH

Oops! This is the second instance that I'm aware of the Polyglas may have been used. Two data points is a start but certainly far from conclusive.:CharleySucks:

34,932 to be exact.
The same could be said about a 1970 L78 Camaro with a TH400. ;)

The Corvettes never wore Polyglas .. the wore Speedway Wide Tread F70-15’s from ‘68-‘72.

I am not saying this is the only one.... you just asked for proof, which I gave you documentation from GM that they were available starting 2Q of ‘69. I also gave you pictures... These came from a respected member of the Camaro community... contact me with further questions.
