They will match quickly after a turn with the slip into the print of the front.  Once the rears are in a compacted track  that matches then they will try to stay there better. The problem is is when the rears don't match the front they then try to spin into the impression of the lug from the front. But if the drivers & duals are not matched the rears are trying to "find" the impressions all day.  The idea is to get both ends "working together"
