MPG drop

All of a sudden my MPG has dropped by 10mpg at cruise. I used to get 60 at 50mph. Now it's 50 at 50. Only major change was a new set of Walmart Goodyear assurance tires in stock size.
Is that the probable cause? We're the Oem Tires that much better?! Or is there a checklist to go through to find an issue? I'm at 55k miles. Mpg got worse at 45k along with the tire swap.
Any ideas?

Perhaps you've been watching the MPG drop during a regen cycle?
