hey all, just wanted to get some ideas about varying my tire size. 2013 wrx, stock 17 inch wheels, and stock suspension except for some beefed up sway bars front and rear. stock tire size is 235/45r17. I'd like to know about doing a 245/45 or a 245/40. Basically i'd like a little bit more width. Does anyone foresee a problem with adding a centimeter across the tread path? I wouldn't think so, but I'd like to know if there's something I'm missing. Thanks.
