The tires I am looking at are regular all-season tires, not aggressive knobby off-road ones. (also, I have 12.5mm spacers up front, 20mm in rear). Thanks for the help.

Kind of, in your example a 2" increase in tire size would be like a 1" drop. I.e. The top of the tire is one inch closer to the top of the wheel well.
The difference though are items that move in direct relation to the wheel hub like ball joints. When lowering a car, there is no change in the distance from that joint to the tire. The entire assembly move further along its upward travel. When installing larger tires, the distance from those components attached to the hub is now reduced. This will cause the tires to rub on certain components. This is regardless of any amount of lifting or raising of the suspension.
Think along the lines of trying to run a wheel too small to clear a caliper
