Background: Yesterdays snow and ice event means it time to mount up the studded tires. This is my 4th year on these. Nokian W106 35 mm, Surly cross check, 8spd IGH. I didn't ride much last winter due to an injury but I will be riding daily this year.

So since it's been a while I'm just looking for input and advice on tire pressures from those of you that ride these W106 tires. I have a tendency to run all my tires at full pressure (65psi for these) mostly because I'm pretty big and I want the least rolling resistance but, I know that they may perform better stud-wise and traction-wise at lower pressures.

So, what pressures do you run and have success with and in what conditions?
