My Peugeot 5008 has just failed MOT because of wrong front tyres size. The driver side is
215/40/18/85/W with (Tread, outside 5.5-centre 5- inside 5.1 mm) and the passenger side is
215/45/18/93/Y with (Tread, outside 3.1-centre 3.4-inside 3.5) and. The garage is on the wrong side since they chose and changed the drive side tyre seven months ago.
My question is; should that had a bad impact on the car during the seven months ago? I want to understand if there is anything else should be checked before replacing the wrong sized tyres.
