• If I want to end up with a 28-30mm wide tyre what inner rim width would be best'est for handling/everything?

    21mm? or wider?

  • 21mm?

    19-20 is the safe bet. If you go too far over that at the front your tyre is so opened up compared with what the manufacturer intended that the possibility of running off the edge of the tread mid corner heaves into view. You have a bit more wiggle room at the back because it leans less and oversteer is less likely to break your face.
