I dont know if they sell what U r looking for but if you are near Apopka, I can put U in touch with the service mgr at Tires Plus on Semoran Blvd not far from I-4.
I founded a place in orlando so I will stop by there tomorrow morning. My wife called 6 places for that tire size and nobody carry that size. Yall folks down here must don't ride no bigger then eighteen on vehicles . LOL
