Driving straight on dry pavement these tires have the same or maybe slightly (very slightly) worse rolling resistance than my old ones at the same pressure, summer/late spring temperatures. After several rainy days over several tanks I can say these tires have much less rolling resistance than the old tires when wet. Rainy days no longer keep me from getting 50MPG. I wonder how they'll be next winter.

Hmm that is interesting about the rolling resistance dry/wet but great for rainy days. We sure seem to be having a lot of them over here...

Thanks for the updates enkid!

I'm saying - dry compared to dry, while rolling straight, in mid 60's F average temperatures, the new and old tires have about the same rolling resistance.

Wet compared to wet, in mid 60's F average temperatures, the old tires had a much higher increase in rolling resistance than the new ones do.

Winter update.... 15000+ miles, tires at max sidewall (51psi). Good comfortable ride, steering very precise. Rolling resistance a lot better than older tires in cold weather. I guesstimate 5 MPG cold weather improvement for a 45 mile mostly highway trip vs. Eagle GT tires.

Isnt that a really harsh ride running at max sidewall pressure.

I notive a HUGE difference between 34psi(what they put in at the tire shop) and 40-42psi(what I inflate them to once I get home). It is not a bad ride, but noticeably more firm.

I could only imagine 50psi must feel like rolling on solid rubber tires with no air needed : )

I run anywhere from max sidewall to 60 PSI, and while the ride is definitely more firm than at the door pressure it isn't "harsh" at all. When driving through switchbacks in the mountains 32 PSI would actually allow for sidewall roll, while higher pressures maintain the sidewalls.

While generating a much smaller footprint, fact...tires at the factory recommended pressures, that's where the nice cushy ride and shorter stopping distances come into play, and actually safer handling; good alternatives to just getting maximum fuel economy, imo.
