So what you see is 13.5mm, which scales up to 17” - assuming the model is accurate to 1:32 scale.

Hi Andy,

13.5mm corresponds to 17"-1.5"=15.5"
See Mick Kerr's post #2:

The visible diameter for an 17" hub should be 17"+1.5"=18.5" 18.5"x25.4/32=14.7mm
For a 18" hub that means a visible diameter of 18"+1.5"=19.5" 19.5"x25.4/32=15.5mm

If the DTM cars ran on 18" rims, the visible diameter should be 15.5mm, not 13.5mm.

I guess that's what caught my eye.
