The 5 wheels on my '69 Barracuda are X9 color as called out on the build sheet.
do you have any detail pics of that tire? original spare to the car?
your sheet shows T74 E70-14 "white streak" fiberglass-belted.
I haven't seen any 1969 dated fiberglass-belted FIRESTONES
I’m not sure if you are saying you just never saw any or you aren’t sure if any were OE in 1969? I bought a new 1969 Road Runner that came with Firestone Wide Oval red streak tires. They lasted about 3,000 miles.
the key wording is "fiberglass-belted"
when Firestone went from bias/ply to fiberglass-belted they didn't re-brand the RWL appearance of the tire - both were "
WIDE OVAL" the bias/ply tire was "Deluxe Champion" VS. "SUP-R-BELT" for the belted
Firestone "WIDE OVAL" Deluxe Champion = Goodyear "SPEEDWAY"
Firestone "WIDE OVAL" SUP-R-BELT = Goodyear "POLYGLAS"
1969 383 Road Runner had Goodyear Speedway or Firestone Deluxe Champion STANDARD
fiberglass-belted Goodyear Polyglas was OPTIONAL
