Yep, and in this case, I am going to a 7% larger tire, so it is changing gearing too. Rolling resistance, aero factors, rotating mass, gearing, pumping losses..anything I am missing on the list of variables?
I guess the only way to know is stick with the one variable; use a wider tire with a lower profile ratio to keep the diameter the same, same tire model, same rims, and do some a-b-a testing.
