Snows are great on the 5. I would recommend a full steel wheel and tire package from tirerack.com. They will ship them mounted and balances.
I would suggest doing the research yourself though, as each person will have their preferences.
One thing I can reiterate though is to go for the 205/55 16s for winter. You can get 17's, but the added expense of tires and mounting will nearly cover the 16s mounted on steelies from tirerack. Also get yours early enough to put a few miles (about 500) on the set before the snow kicks in. This wears off the mold release and opens of the micro air pockets in the snows to make them winter-ready.
Thanks, that was helpful esp. the tirerack suggestion. I was looking at steels & snow tires for her Hyundia when she had it, but that thing was great in the snow if it could get out of the driveway. I've started doing some research on the snows, and after reading some of the posts, was leaning towards 16's because of the prices. Indianapolis doesn't get real heavy snows, but with the distance of her drive(since right now isn't a goodtime to move), whatever I can do to help out, and keep her happy and safe, I'm willing to try.
