Hi all, I am new to this forum, so if this a question many times asked forgive me.

We have an old Mk4 Fiesta Black (model not colour!) 1.25 zetec 2001. My newly test passed kid bought it without guidance and it had many things wrong with it. After sorting most of it out for her I noticed that all of the tyres were of different sizes (yes really). It has the 14 spoke 14" 5.5J (see picture) wheels. Numbers on rear are 156Y-AA & GD791-41. The tyre fitted to the spare is 185/55 14, but the tyre fitter put on 4 off 165/65 14 which he assured her are the correct tyres for the car.

As all of the specs seem to think the car originally came with 13" wheels can someone tell me what size tyres are the correct fitment. She has now smashed one of the alloys and I am trying to get hold of some but wnat to make sure we put the correct tyres on. I would like to stay with the 165's as they are almost new but don't want her driving on the wrong size tyres
