This is what the interweb is giving me.

5 44 =
TRANSMISSION: 3-Speed Automatic
TIRES: F70x14 Red Sidewall, Steel Belted

3 46 =
TRANSMISSION: 4-Speed Manual Floor Shift
TIRES: F70x14 White Sidewall, steel belted

The tire code does not appear correct as the window sticker lists red streak tires.



The only problem I see with the above decode info is - the tires were NOT "steel belted". They were "nylon ply" & I have not seen any evidence that anything other than a Goodyear "SPEEDWAY" tire was used in this application. The 44 code "red streak" F70-14 tire was STANDARD on the '68 383 Road Runner & the 46 code "white streak" F70-14 tire was a "NO COST" option. The fact that it doesn't appear on the window sticker MAY be as simple as it wasn't a "cost" item.
