I am not disagreeing with any comments made but just for the record……..
I have had my 2006 built car from new and been a bit bemused with my wires and tyres since my first tyre change.
My local tyre man, with Morgan experience, was sure the rim profiles were for tubeless and were c/w sealant, not a rim band.
But, there was a large yellow label near the spoke well clearly stating inner tubes must be used.
I believe MWS stainless went tubeless from 2008 yet my original tyres were Continental tubeless!
My car was registered in Feb 2008, the tubeless tyres originally on the car were from last quarter 2007 and my wires also have the yellow sticker. I'm picking up the spare today so I'll see what the yellow sticker says. I could just be on the crux of the change.
But it would be interesting if inner tubes are recommended as clearly the black silicone band was pretty poor on the wheel I inspected.
Update
The yellow sticker just gives cleaning instructions of the wire wheel no mention of inner tube or tubeless< And it appears they have sealed the leak with their black latex/rubber type sealant.
