I wouldn't accuse (m)any manufacturers of being "environmentally conscious" solely out of the good of their hearts, but don't forget they also have to meet CAFE fuel economy targets, or pay penalties.
As with any cost vs. fuel consumption issue, you can be pretty sure there's a spreadsheet on the bean counter's computer just about tire selection!
