225/45-17 is a good size for 17's. 235's run the risk of rubbing unless you really do your homework, and it's not just the fender you have to worry about, but the struts too. I ran 225/35-19 on +45mm wheels and there was about 1/8" clearance between the inside of the tires and the rear struts. A tire that is slightly taller than stock is generally desired by most people on here, who are typically of the opinion that the stock 215/50-16's were a little small. My 225/45-17 setup did not rub at all on my car that was lowered on Eibachs and Konis, but did rub on my car that ended up having BAT springs on it (I thought it was stock). The PO of the eibach car might have rolled the fenders, I don't know.
215/45-17 on a stock car that sits like a 4x4 look goofy IMO. Here's an example of 215's on a car that is slightly lower than stock-
