I built my own "homemade" studded tires with a reasonably stud free center section.
On mostly clear roads I run at full (65psi) pressure. This gives a minimal stud contact, and wear, on the straight, any turn, and contact enhances.
Nasty weather prompts me to reduce tire pressure, (~40 psi) for solid contact from both center rows and outer row grabbing on any turns.
Very nasty? I lower seat ... allowing "skiing" with both feet.
