stock ms3 wheel weight

[cghms3]

Hi - does anyone know the stock weight of the 2009 mazdaspeed 3 wheel - Im looking for a wider wheel - Is the stock wheel 7" wide? If so, I would like to get a 18 x 7 1/2" wide wheel with a 18/40/225 tire. My goal is to have a wider wheel/tire but lighter than the stock wheel/tire combo - Thanks! P.S. - Is it a 50+ offset?
