SUV tires on a minivan?

Hi,
I have a 2001 toyota sienna minivan. I'm getting some snow tires but the place I tried only have SUV snowtires that match my current tire size (http://www.automotiveforums.com/vbulletin/#). Are SUV tires ok on minivans?
My minivan handbook says I can choose between the following sizes:

205 x 70 x15 (which is the size of the SUV tires (http://www.automotiveforums.com/vbulletin/#) they have and my current ones)

or

215 x 65 x 15 (which is the size of the none SUV tires I would have choosen)

Any advise would be most appreciated.
