I have one only 'Vette unused spare of what sounds like the same Goodyear thin white stripe as the above poster's set of 4.
Blackwalls out w/ blackened whitewalls inside is the way to go as finding a set of original blackwalls may be difficult.
Here's a few pics of the one here also decode as much as I understand, anyone please speak up w/ better info.
