	My memory is a bit fuzzy on what the size markings mean on racing tyres and as i'll be selling some soon I want to get them right. I have a set of four Michelin 23/57-13 Slicks. As far as I can remember this means that the contact patch is 230mm wide, the tyre is 570mm diameter and its designed for a 13" wheel. Is that correct? Matt

	That's right. and it's 230mm TREAD width, not tyre width. A 20/57 13 tyre is roughly the same as a 235/45 13. I've got a set of 160/530 13 michelin slicks on the pug atm and they're wider than 185s.
