I have a collapsible spare with the tank (the carboard label is in poor shape though);
I am not sure what it came from - I got it with parts from a guy who parted out mostly Firebirds (but some Camaros too) in the 1980's.
The one I have does NOT have that tread pattern;
Mine is an RF coded wheel with a M1/9 (so presumably a 1980 wheel), and it's a G78-15
Is there a resource which lists wheel codes ect for these types of wheels (and tires)?
