Kelsey Tire is responsible for all of the Goodyear tires on the reproduction market.

Kelsey Tire Polyglas tires are on the "Performance 2" page.

The F70-14 Polyglas "white stripe" tires weren't available in the past but are listed on their web site. Maybe they are "new" to market as are the long waited for "red stripe" G70-15s for the '69-1/2 6bbl cars.
