Continental Eco Tires......

I kind of figured that much. I'm just not clear about how they achieve the lower rolling resistance. Is it by compound and/or tread design, or is it simply by way of being made to run at a higher pressure?

Do you know if anyone here has tried them out and collected data on FE and rolling resistance changes?

Basically RR is caused by the amount of deflection, the amount of rubber being deflected, and the internal friction of the rubber (hysteresis).

So when a tire manufacturer wants to reduce the RR, he will take rubber out of the tire and / or change the rubber to one with a lower hysteresis. Both of these things negatively affect treadwear and traction (especially wet traction)
