Re: Wrangler to Mustang.
I would get it and a second set of wheels for the winter with some descent tires.
In PA we get plenty of snow and I drive the mustang all year. With the TLok and Traction Control along with a OEM set of wheels with all season tires, I had no problem this past winter. Just be careful when you drive.
I have heard that blizzaks are amazing but haven't tried them myself.
