i am going to go ahead and say that it may fit okay but will prolly rub anytime you hit a bump or dip in the road or especially under normal weight.
by stepping up the size of the rim generally you HAVE to step down the size of the profile.
check out this tire size calculator at:

ideally you want to keep the same height of tire wheel combo (like when you put the 2 standing up next to each other) so as not to throw off your speedo and abs,,, etc.. ect...
this is why most people run such small low pro tires with big rims like 20"+.
if you figure out how to have your cake and eat it to let me know
