Years ago I made a set of cones on my lathe. Not a difficult job, especially as they are used so infrequently they can be made from aluminium alloy.
I was quite proud of them and when I needed new tyres I took them with me to my local tyre fitters. Only to be told 'No worries mate, we've got a set and are quite happy to balance wire wheels'.
Ah well. At least I've got them should they ever close down.
