When it comes to 'stretching things out a bit' I've done just about everything in the book, but I have never worn a tyre to the casing/belting. I run my rear tyres until they have a slick 10mm band forming a flat strip in the middle of the tyre - not saying it's advisable, but I haven't had a problem with doing this. I'm slightly more fussy with the front as it has a detrimental effect on the steering.

As I have said to Graham previously, I tend to switch my front and rear tyres over every year to extend the life of them (the front tyre gets extremely little wear).
I have said (I think) I changed my rear tyre at 5300 miles (there was a thin patch where I had presumably skidded) but friendly Woodrup of Kirkstall recently said my front was still OK and it has now done 6443 miles (too much precision?).

So Good Old Graphene say I!
