Not all of them. COPOs could be ordered with COPO 9737 which included 15" x 7" wheels and E70 x 15 RWL tires, Firestone Sport Car 200 or Good Year Wide Tread GTs.
COPOs could be ordered with any of several optional F70 x 14 tires: RWL, red stripe or white stripe. Later in the model year Polyglas belted tires became optional and one documented car is known to have been built that way. Uniroyal Tiger Paws were also used along with Good Year Wide Tread GTs or the Firestones shown in the picture. At least one ZL-1 was built with the Firestones. The "Good Year only" for COPOs is nonsense.
The Firestone tire you have is not reproduced. An NOS set of 4 would be mind-boggling expensive.
