08 matrix and steel wheels

have a 2008 matrix xr with a 1.8 engine looking to buy steel wheels to mount some blizak 16 in tires on for winter
what do I need to know and what rims will fit from which cars:cool:

Determine the offset and bolt pattern for your wheels by going to a internet site which sells wheels and looking up your vehicle. Then look through other Toyota models for one which uses the same offset and bolt pattern as your vehicle.

I would buy them from a salvage yard if possible.
