Technical Replace wheels with 205/45 R17 with 215/45 R17 or 225/45 R17??

Hi,
Not looking to pimp up my car just replace 2 defective stock wheels that are causing tyres to loose air!
Could find replacement stocks anywhere.
Does anyone know if I could replace with a full set of either 215/45/17 or 225/45/17 that I've seen?

That's tyre size but you say you're trying to replace wheels?

The wheel sizes is usually 6.5J 17, some T-jets run 7J 17's I think.

What's size is stamped on your wheels at the moment?

What model and year is your car

Photos of your existing wheels?

Hi,
Probably wasnt clear enough sorry.
Cant find matching stock wheels with tyres but have found Fiat 4 stud wheels with 215/45/17 tyres on one set and 225/45/17 tyres on another set.
I assume the potential replacement set of wheels will be 10mm and 20mm wider than the wheel/tyres allready on my car and slightly larger on diameter.
I suspect the increase in diameter could be less of an issue than the increased width?
