Application for these Goodyear Polyglas 14 x 7 F70-14

[SmallHurst]

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.
