It would appear that the rear tire is lower profile because of its lower number, but due to the rear tire being wider, it has a similar overall diameter.

Not really...if the sidewall heights are different, that would also make the overall circumference to be different as well. The sidewall
height of the 255/50-19 tires in the front and 285/45-19 in the rear are the same, it's their sidewall to tire width
ratio that's different.
