I have 700x28 Schwalbe Marathon (NOT STUDDED) tires on my bike. They have some good tread to them, but are not knobby. Suppose I will be commuting this winter on them. The roads I will be on are well cleared and salted. There is a chance of ice however as temperatures are freezing.
I have these tires at 100psi currently. Will lowering the pressure be beneficial when riding in these conditions? I'm most concerned about ice.
