I had a slow puncture a while ago and got the tyre replaced on my Renault Clio because it was bulging and non salvageable.
Since then I've been losing pressure in that tyre fairly rapidly.
I've had the tyre resealed 3 times now and I'm still losing pressure in the tyre (from full to flat in ~3 days even with no driving being done).
What else could be the cause? I'd rather not shell out for a new wheel and the mechanics say they don't know what's wrong with it.
