Went on a little 293 km (182mi) ride yesterday.
We got into some beautiful country, most of this was fast (60-100 km/hr) riding on forest service roads but we did get into some crawling through deactivated areas and I'm really impressed with the tires so far. They perform well at the higher speeds, but seem to work really well crawling over logs, roots and slippery rocks in the slower going. I think I'll rotate the tires every 500 km and see how long they'll last but everything is positive so far. I ran them at 12 psi, but think I'll try them at 10 psi next ride.
The machine is awesome, I ran it in eco mode all day, even at the faster speeds. This thing seems to love 85 km/hr and 6500 rpm, it is very comfortable there and runs with very little effort. I did add 10 liters (2.5 gal) and got back to the truck with one bar left on the gauge, so very happy with the fuel economy. On my shorter rides I have ran it on the sport mode and it does make a power difference, but this ride was about finding the range on a longer trip. 32's seem to be the sweet spot with tire size as well, the lighter weight Terra Hooks didn't make hardly any difference in power output and they are amazing through the obstacles. I'll update further as I ride. I also am running 1.5" spacers all around, so my width is sitting at 67".
