For the OEM tire, I feel that the 'widest' place is just where tire meets the wheel, with the width of the tread smaller than wheel width.
So the key is the definition of '215'. Tires with the same 215 width can have different tread width for sure.

i see what you're saying. for the tires on other cars that are 215mm width, but have some bulge in the sidewall, inspection of the wheel package should show that they're running a narrower wheel, somewhere near 7"-6.5" wide wheels. by using a 7.5" wide wheel, you're using up that sidewall bulge in a different way.
