After reading so many kind responses about tires and brake bridge and fork interference I realize I might have been too optimistic in the first place.
Does a bigger tire grow in height and width in the same numbers?
It is hard to predict. Different tire have different profiles. Some are taller than others. Also rim width affects the hieght but not by a whole lot, until you get to really wide rims. Best thing to do if you want to know is ask someone with a particular tire to measure the hieght from the edge of the rim.
