I think the price is simply down to the small numbers involved.

I would agree with that. Look at any Cooper Bristol for example and the tyre size is very different from that used in period. I'm not sure whether the cart came before the horse as they all use new wheels which are smaller and wider.
Sometimes we don't have a choice; for example F3 500s ran 4.00 x 15 on the front in period but we have to run 4.50 x 15 now as Dunlop say they no longer have a mould. Having said that they miraculously found the mould for the pre war 3 stud pattern after Blockley introduced theirs.
