WTF!!!!!!
settle down.

1. do the tires fit? Duh. don't worry about what doesnt matter.
2. what you ganna order 17 and have a tire that doesnt fit!!
3. if you go to TIRERACK . Com the list the specs (measurements) of the tires. you can make comparisons there. don't try to go by the 55 or 60 or 195 etc. Those are "RATIOS" so they are not the same between tire sizes. At tirerack you can see the width in inches and the diamiter in inches. Don't go smaller on the diameter, you'll get less mpg. try to go 2-4% larger on stock diameter, it will lower you rpms when you are going down the road and that helps mpg.
4. In my personal opinion, going skinny is not all it is cracked up to be. reduces handling a great deal and you are stuck with the bad choice for a long time. Most eco mods can be undone the next weekend. Not tires.....you buy em....you own em.
Try to get a taller tire. inflate it to 45psi (for example) and try to find a tire with better RR. just my .02
