I am a new Prius owner and am planning to upgrade the OEM 15's with 17x7.5 Katana wheels- my question is has anybody tried 225-45-17 vs the 215-45-17's? The 215-45-17's look stretched on the 7.5" width. Will they fit or are they too wide? The size is almost exact to the 195-65-15 OEM tires. I have done no suspension mods. Thanks Prius Experts!
