If you're lucky, the LRR tires might last a little longer than the low end tires. That would somewhat offset the cost difference.

On the other hand, tires with a high or very high treadwear rating will definitely outlast the LRR tires, but return consistently worse FE.

On the third hand, tires that are nearly bald give improved FE compared to the same tire with full tread thickness. So, if wet/snowy weather isn't a big factor where you live, drive 'em until the tread is smooth as a baby's behind. Don't go crazy though, lack of tread WILL cause you to hydroplane and crash if it's wet and you're not careful.
