They are still available- may be special order but you can get them. A lot of European cars still run them I was told by my local tire guy. They are allowed to keep tires on the shelf for like 2-3 years and have to dispose of them. They get sent here where a tire is able to be sold as “new “ till age 5. Lots of info on boob tube about date codes and tires and what to look out for.
