I did a quick google search, all I could find was people saying it's bad to ride with a slow puncture and not worth it but they give no reasons.
The back tyre of my honda cbf125 has a slow puncture (takes a couple of weeks to go flat when left on the drive). I think the offending 'puncture' is a crack or split about 7-8mm long on the part of the tyre that touches the road. It bubbles when I put soapy water on it. Anyone know of any reason why it is dangerous to ride with a slow puncture?
