Can't answer your question, too many variables. But I did look up this tire size on Tire Rack and it issued this caution.
Tread patterns must often be tuned to accommodate different tire widths. While tires shipped will match your order's specifications, photos used only represent typical sizes.
I have no idea as to what this means. But if i were you, I'd call them and discuss your plans (plus they're one of the best to buy from.)
There are a lot of factors that go into tire size, geometry, suspension loading, shocks & struts, AdvanceTrec, etc.
Plus your new diameter will be off by 2.8%, and the new size should be recorded in the BCM.
