Hi all
My question is do all Slotit rims come with the same shoulder size and on their new easy to understand wheel chart why not put the actual rim size as well as the overall size?

I am unsure what you mean by shoulder size, but the central ridge is the same width and height across the range, with a possible exception on the F1 hubs.
Most size slot it tyres will fit the 15.8, 16.5, 16.9 or 17.3 rims, and give the dimensions listed on their chart.
