   Sorry. Am I missing the point you are trying to make??   
      
   When I but new tyres (which I'll have to do, again, soon.) I buy 15 inch   
   tyres (I think). Is this not the diameter of the Hubs on to which the   
   tyres are fitted??   
      
   So the inner circumference of the Tyres 'hole' is about 15 inch diameter.
