They do, pretty penny but.

I guess I should clarify. In February I bought 5 each 4.50/4.75 x 21 radials (I think, stock size for Model A 21s anyway). At that time they only listed tubes for bias ply tires in that size. When I asked what tubes to use, they said they use the tubes for bias ply tires. That is my entire experience with Model A tubes in recent times.
