Best LRR tire in many europe car tests have been Michelin energy saver.
However in latest auto motor und sport magazine there were a ecotire test and the winner were new goodyear efficientgrip by slight margin to michelin energy saver!.
So at the moment I would shoose efficientgrip because it is more also more cheaper
. One good way to choose a tire is to choose the same tire what is in car manufacturers "ecomodels".
Third option would be Kleber dynaxer hp2 which have been second in many test in LRR. Kleber is a Michelins sub-brand.
There are also some other/better LRR tires but they havent been in test so you cant tell they LRR capabilities from what the manufacturers tell you. For example Pirelli P6 should be very good in LRR, but it was horrible in the same test mentioned above!
I have also noticed that it is guite hard to find very tall tires which have also been good in rolling resistance in tests.
I chose to buy Toyo 350 in size 175/80/R14 which also should be LRR tire. At the moment im satisfied with my tire, because I havent tried Michelin or goodyear. At least my consumption figures went down when compared to my winter tires
