I realize that the radius of the same size tires of different brands can vary, but it would be very small. Going from a 180 to 190 with both having the same 55 aspect ratio, the difference in radius should be about 1/4 of an inch. So in theory, that should be how much higher the bike sits.
Could be.....but given the "butt and feet height-ometer" feels like more than that. Be cool to know exactly though...
