Compatibility with other Mazda 16" rims?
 

We'd like to buy another set of 16" alloy rims as the ones we have are kind of beat up, and have snow tires mounted on them.

Is there a list of cross-fitments anywhere? It seems that many FWD MAzda's use the same size rims.

Check with TireRack.com for new rims and check at Car-Part.com--Used Auto Parts Market for used rims.
