Firestone 721s are still available from time to time. Apparently they do a run of them every so often. I just ordered a set this week from an online source, Tirenet.com, for just over $80 each. I was concerned about the Firestone brand at first, but John at Tirenet assured me they were a very well built tire and the best choice for heavy cars as they have the heavier load rating, yet will still give a soft ride. I have used Broadway Classics before when the Firestone's were not available, but do prefer the name brand (even if it is Firestone) to some off-brand tires. John -- 78 NYB
