That's a lot of pressure loss on a daily basis. There's probably nothing wrong with the tyre. Depending on who did the tyre change for you, they may have inadvertently damaged the "band" that goes around the centre of the wheel, in which case air will leak. That happened to me a couple of years ago, after having 5 new tyres fitted while the car was in for servicing, one of them went flat overnight. So I took the complete wheel/tyre to a local tyre specialist (where I should have gone in the first place) and they sorted it while I waited. (I have added a second picture to show the damage in the midddle of the band).
