345/55/R15 Tires

I currently have a set of 345-55-15 BF Goodrich tires on my rears that are beginning to show some signs of wear and cracking etc. Looking to get a new pair. I have not been successful in finding a new set. It seems BF does not make them now.

Can anyone suggest a manufacturer that carries this same size tire, or equivalent? I have looked at MT, Hoosier, but not much luck.

Thank you
