Last week on my way for a ride I noticed my back tyre completely deflated
I decided to inflate it and just see if it's not a slow puncture before I go ahead a replace the tube (wasn't in the mood that day).

So from last week Thursday to today the tyre is still exactly the same as when I inflated it after the flat.

Do you guys think I should change the tube anyway or can I live with the mysterious once of flat?
