I have Nokian WR tires on my Canyon. There is a very noticeable difference in rolling resistance between 37 and 47 PSI. I have not tried higher pressures.
The Canyon responds very nicely to DWL. Either a vacuum gauge or a Scangauge is necessary because the throttle plate does not have a consistent relationship to gas pedal position.
I find it possible to hold 5th gear down to about 22 MPH on a smooth, level road. It will even accelerate from that speed, although only at about 1 MPH per city block.
