So I am new here, just picked up a 07 Sport and like I said it has the stock wheels. I also have set of 99-00 si wheels from my Civic. If I understand correctly these are both 15x6 wheels with similar offset(?) and comparable weight.

With that in mind, is there any reason to run one set as summer more than the other? Aside from ascetics that is.

As it stands I would probably run the em1's during the winter. I feel they are more likely to get stolen, so may as well have them on when less people are just roaming around.

 

I'd run the heavier wheel for the winter tires so I could get the light wheel in the summer with the sporty tires..
