Just returned from a 2,400 mile road trip to Portland. As far as the car and tires, it was almost a perfect trip. I used the "Autopilot" and Traffic Assisted Cruise Control and there were a few phantom braking incidents. As far as the Nokian One tires, we averaged just under 253 wh/mile for the trip, with 44psi in tires at about 65 degrees. We had temperatures over 100 degrees and lows were into the 60's on this trip. Handling was fine at speeds up to 80 mph. I did note that energy usage was lower on the way home as I kept the speed down (average about 70 on interstate 5) to limit the last 440 mile drive to one supercharger stop. AC was in constant use during the final drive as temperatures were up on that leg of the trip. I would say I am pretty satisfied with these tires.
