dude, if you have room, you should keep them. you never know when you will need them again after hitting pot holes or railroads or rocks or whatever. and you may appreciate driving with those wheels again after a few years with aftermarket ones because the offset and width difference does make a big difference in steering feel and response.
if you ever go to the track or autox, you probably wanna use those stock wheels with better tires, etc.
