Do you find much performance difference between a 35sh 26mm (cut-down rear) tyre and a 37sh 30mm tyre?
I started on 35sh 26mm cut-down rears but the wear was huge. So I switched to 30mm 37sh; I found slightly less traction if anything, but wear massively reduced. Only thing is it can be hard for some cars (e.g. Mi6) to fit a 30mm rim.
