Price may or may not be a factor but the LRR ration is the MOST important. Anyone know of a (free, internet-based) chart that shows an outline of all these types of tires? None of the typical internet suspects (discount tire, tire rack, etc) offer any type of sort based on "rolling resistance" so I thought I'd ask here.
Responses like "I liked my XYZ tires and got 2 gazillion miles out of them" are of absolutely NO value here so don't bother posting such jiberish. I am seeking cold hard FACTS and details, not opinions.

OK, attached is my 4-year MPG spreadsheet on my Prius. Remember that your HH is heavier and uses larger tires so YMMV. I ran my Integrity tires (Yuk) for 45k miles, Michelin MXV4+ "Energy Saving" Tires for 55k Miles (Very nice tires, could have gone 60k, somewhat better MPG and much better handling), and now have Nokian WR tires (early results - even better MPG, great wet and snow traction, expect 50-60k miles, a little noisy - less with the WRg2, and again good handling).
