Replaced Tires with non-LRR tires gas mileage horrible 50 mpg to 37 mpg please help!!

I thought gosh I could save money and buy my tires online then have the local tire shop install them and save money. So I got on amazon and found the same size tire for my 2014 Prius C and thought c'mon its just a tire and if the tread depth is the same, width, height etc etc. that I wouldn't have any problem and that my car would smile and thank me.

Instead, my car's battery hasn't been charging above 2 bars and I've got new tires but my mileage city went from 50 to 37 and it was ever since I put new tires on my car. After having over 1,200 miles put on the car and a few gas tanks I'm concerned.

I know that every 10K miles my tires need to be rotated according to the computer on my dash as it alerts me. As soon as I saw that notification instead of rotating my tires I replaced them. That notification is still on. Do I need to find on youtube how to reset it ?

I didn't know the difference in LRR tires compared to HRR tires I didnt know that was a big deal and went with whatever amazon recommended.

Please help.

Thank you
