The tyre fitted without the tube has held its pressure OK and I had cleaned up the rims on their hidden parts before. The local garage chap pointed out that the 409 wheels do not have what he called a safety rim -ie a a way of keeping the tyre on the rim in the event of a blow out. The inner sides of the Avon tyres have hard lines in them and the evidence of rubber dust suggested abrasion.
I might get on to Vintage Tyre Suppies in Lymington UK as they are likely to be familiar with the older car issues. Thanks for assistance
