Right now, all of my vehicles have good/new tires and will not be needing new tires for some time. But, when I am looking again, I will "strongly consider" LRR tires after(AGAIN) more research and cost figuring.
I currently have tires that show poor(high) rolling resistance compared to owning other tires that(on the same vehicle) showed lower rolling resistance. And I see no MPG differences between the two.
I also read Waaaaay toooooo many reviews from others(especially on Prius') that claim(no, I won't provide a link)...they see no fuel economy gains from LRR tires compared to they're previous non LRR tires. And I'm not speaking only of a comparison between G/Y Integrity's vs ECO tires. This could vary by brand!
The LRR tires on the market today (yes, I know to be careful of how I use that acronym, per CapriRacer) do tend to be a bit weaker in terms of traction, handling and treadwear compared to their more traditional counterparts. This is an area that has seen improvement, but is still lacking for some drivers.
I also wholeheartedly disagree that differences are not observed. The Priuschat site has dozens and dozens of threads where people have swapped out their tires for a set of non-LRR tires and have seen a significant drop right away. The individuals who do not notice a change, are probably owners who drive cars that average 20-25mpg...so a 3-5% improvement is unlikely to be noticed. Compare that to a Prius, where 3-5% of 45 mpg is 2 mpg.

Completely agree.

See above.

So even though a tire is labeled as "LRR", it might actually have a higher RR than one not so labeled - and not because the non-labeled tire COULD have been so labeled.
I almost forgot about this - thanks for the reminder.
