Nope they last made those tires about 1975.. As Karen said if you find a good set they will cost you lots.. Even if you did find a good set its really not a good option if you plan on riding the
bike a lot. as the best case they are about 45 years old.. so its not a matter of if they fail its when they fail.. its super easy to convert to a modern wheel and tire option on that
bike, and in my opinion the best way forward..
