Cobra wise there were British and American versions of street and race tires 1962 through 1965. I know some about the most common ones but SAI used many different casing designs and many different compounds.
British Goodyear Motorway Specials
American Goodyear Sports Car Specials in at least two different tread patterns in 6.00/6.40 size.
Goodyear G8 tires (stock for 5.50 wide wire wheels) in 7.35 size.
Goodyear Power Cushion (a roughly 65 series aspect ratio) 7.35 size after the change to 6.00 wide wire wheels
Goodyear British Goodyear made 7.35 street tires on some very late Cobras, similar to the Power Cushion design
Goodyear Sports Car Specials in 6.50/6.70 size in both standard and lightweight versions; the light weight versions have the raised letters LW molded into them
Goodyear Speedway Specials in 6.60 size for tracks like Kent Washington (also used on front of Ford GTs very early after SAI was assigned GT40s to make into winners)
Goodyear Stock Car specials in 6.50/6.70 and other sizes in various treads and compounds (6.50/6.70 also used in early GT350 racing)
At least one late car got 427 Cobra 8.15 Blue Dots
One late car was invoiced with a set of 7.75 GT350 Blue Dot tires

There are others I just don’t know their identity. Very little about Cobras is simple. My notes on "COBRA" engines is about fifty pages long. My notes on electrical parts for just CSX2201 and later cars is almost twenty pages. Tires are a tough subject because so few have survived. I have or have had or had access to examine most of the versions ever used on street cars that were made in the USA.
