If the rut is deep enough and solid enough there is nothing you can do about it. That is NOT the tires letting you down.
Too bad the ruts can be hidden by snow.
perhaps rut was a bad choice of words but the tyre was deflected and then SLID out. From my perspective I did feel a more than a little (and not very gently) let down. But don't worry I am not blaming my Nokians. Everything has its limitations. I will ride home on them tonight just with a little more care on bumpy melting ice.
