An OPTIONAL tire available at $47.95 on a '70 (340, 383, 440, 440+6) 'Cuda is Goodyear Polyglas GT E60-15 w/RWL.
The F70-14 & F60-15 are the only Polglas w/RWLs that I've seen in the "no size" version. Both were used during the '69 model year on various manufacturer's cars. I know of NO other RWL Polyglas sizes used in '69.
With all of the "new for '70" RWL tire sizes, some were late getting in the game. One that was NOT available at the beginning of the '70 model year is the H70-15 w/RWL that was advertised as STANDARD on the '70 Sport Fury GT, early cars were delivered with H70-15 "white stripe" tires (yet the b'cast sheets show "U75" for RWL).
The earliest E60-15 b'cast sheets I have are all from the first week of October '69. I'm sure there are some earlier, but by how much? Who has a 15" tired (non-HEMI) e-body built in August or September of '69?
