15" is GREAT!. Not only will you save a buttload on 15" wheels, but your tires will be much cheaper then 16" or 17" wheels. And hey guess what else...you'll have a smoother ride then 16" or 17" and be less likely to destroy your wheels on the first pot hole you hit. I've always ran 195/50 and 205/50 tires on 15" wheels on all my hondas. I wouldn't have it any other way
