Yep. It seems to take about 1k miles before any tire really breaks in and starts performing at its optimal mpg efficiency. When I put on new EP422+, I notice an immediate drop in mpg. After a month of normal driving, I'm back to where I was.

In my experience LRR tires make a 2-4mpg difference vs. non-LRR once they've "broken in."
