Locking/Unlocking the Centre Diff while moving

They are garbage on icy roads. Yes they are 3PMS rated - but I think if you do a lot of snow and ice, real snow tires are the way to go (I’m not even talking about studded tires). I switch over in November once the temperature drops. But for infrequent snow days - probably fine for an AT tire. I hear the K03’s are a little better.

True, 3PMSF rating is just that the tyres have 10% more traction than this reference tyre.
