SPEEDWAY/POLYGLAS/WIDE OVAL for the look & the experience!!

STANDARD on the '69 440 GTX were "red-streak" F70-14 Goodyear SPEEDWAY (T82) nylon cord tires.
***** some Firestone "red-streak" F70-14 WIDE OVAL nylon cord tires have been found that appear to be original.

OPTIONAL at NO COST were "white-streak" F70-14 Goodyear SPEEDWAY (T83) nylon cord tires.
***** some Firestone "white-streak" F70-14 WIDE OVAL nylon cord tires have been found that appear to be original.

OPTIONAL at $26.45 were "red-streak" F70-14 Goodyear POLYGLAS (T85) fiberglass-belted tires.
***** Firestone did not have a fiberglass belted tire in '69.

All of the currently available reproduction SPEEDWAY - WIDE OVAL - POLYGLAS tires are of fiberglass-belted construction. The Firestones use SUP-R-BELT sidewall design/molds which were an early '70s fiberglass-belted tire.

I'd hazzard a guess that Firestones were sometimes used (late in the year or at certain plants) as the base tire because the availability of the Goodyears was low due to Goodyear wanting to push the "better" POLYGLAS technology or simply because of the success of Road Runner, GTX, Coronet R/T, Super Bee, & Charger R/T exceded expectations at greater that 150,000 units.
