Everyone has there own ideas on what works for them.. Just keep in mind that the rims are $350 + each.. Also, there is no tube to pinch, that's good. But if you run to low you can break the tire bead off the rim.. I run mine a bit higher than most I guess. I keep the same pressure on road and off... For myself I don't find a significant difference in traction from the tire pressure I run on the road compared to lower pressures. I don't feel as confident off road with the tires at lower pressure, they tend to be more squishy and push. Don't feel as 'connected' (to me)...
Also, I don't like to stop five times a day and pump them back up to normal operating pressures. If riders have 'issues' with knob type tires on the road, make sure you have the correct pressure in the tire. Most of the time when a customer contacts me with a question about how the tire is acting on the road, its a direct correlation with low tire pressure... And in the conversation they bring up they didn't pump the tires back up after riding off road...
Play around with pressure and you might find what fits your riding style and riding conditions. Tire pressure will also act different depending on how someone might have there suspension set up... 25psi on five different bikes is going to ride and act different on all of them because of suspension, rider weight, off road conditions, two up riding, fully loaded, fully unloaded.... IMOP there is not a magic 'off road tire pressure'.... You ask ten people, your going to get ten "correct" answers..... but all different.. ::008::
