Re: (swedeman)
If you pull out those foam blocks, it probably would. I imagine they made the well big enough but skimped on cost and weight by putting the mini-wheel in there.
Also, think about it: how likely are you to get non-radial tires? It's not like you could rotate the spare with your other 4. If you wanted a full-sized spare, you'd probably just want to get a steelie and some other generic tire to drive on for, still, a short period of time (but you could drive normally instead of under 50 MPH or whatever).
