Dan...it depends on your tires too. Not all tires are created equal. Falken Azenis 205/50 are wider than most other 205/50 tires. I run my Dunlops for daily driving on my 15x6...and it's fine. It just depends what you're using it for. That's why I'm going to get at least a 15x7 for my Falkens on the track.
