Interesting that the two with the lowest RRC were Conti Vancocontact2 and Nokian Hakko C van tires.

6.4 N/1000kg on Vanco Contact2 its a lot better than 10 N/1000kg in my Hankook Evo v12 K110 tires. I could reduce a lot the city fuel consumption and even highway only changing my good tires (MIchelin Energy 8.5-9 N/1000kg have worst handling on dry and wet compared) with four van tires, ahahah

European Comission lots of info (there is important info hidden in the zips and endless and boring documents ): radius dependance of tire rolling resistance, rolling resistance of large sports tires being better than small "eco" ones, etc. all the test are anonimously so make and model comparision (or brands: van, car eco, car uhp, etc.) couldn't be done but its interesting.
