Incorrect. As ice gets colder, it gets grippier. You'll hear olympic downhill skiers complain about cold ice because they can't go as fast. Skating rinks keep their ice surface just over freezing because wet ice is just about the most slippery thing around and slippery is fast (for skates). But what is good for skates is awful for wheels. Barring the change in scenery and chill factor, you wouldn't notice any difference between riding on pavement and -40* ice.
