I'm about to start on a British Midget of the 1930s,which ran on 12inch wheels with narrow, Knobbly motor-cycle tyres.
I reckon I can use modern Scalextric classic mini tyres.
Having been brainwashed by Euro decimalisation, I can no longer easily relate to tiny fractions of an inch.
I remember that someone in the Autograss proxy qouted Ranch Design wheels that came out as 1/32 Mini wheels - but now I can't find the post.
Could someone who knows their way around the RD list please tell me which is the narrowest wheel that most nearly corresponds to 12 inch diameter?
David.
