What is the definition and metrics of an LRR tire? There is nothing that I'm aware of that shows that an LRR tire is truly an LRR tire. BTW, I have LRR tires on my car but they didn't do any better in FE than the OEM tires that came with the car. What did improve was the performance in the rain and the noise was reduced.

I bought the tires not knowing they were LRR, only found out because some website deemed them to be so.
