I run 215/40-17" with 17x8 wheels. The car runs like it's on rails. One thing you have to worry about running the 215's is that if you lower your car, you'll have to also roll your fenders (or it will scrub, specially in the back). I had to roll my fenders since I have the H&R "Sport" springs (lowered 1.5-1.75" all around). But I tell you, with the lowering and rolling the fenders, the 215's are definitely worth it.
