Tire Width Question

303 7
Why is my stack of 235/45/17 half an inch shorter than the stack of 215/55/16? I measured with a straight edge across the top.

You can't really compare. Even tires of the same width rating have oftentimes wildly varying tread, section, and overall widths. Your 215's likely have wider real world overall width than your 235's.
