Yes I've heard of people running that but I wonder about the other way around.I know guys have ran a 3” pitch track on 2.86 drivers
Never tried to miss match my driver set. But from experience with old bogie sleds with tracks that have rear tensioners in the form of sprockets. A lot of tracks are rotten/ shrunk. Not equal from how there stored. Seems when under load you don’t notice it , but when it’s free wheeling it will start to bind.Mayby for trails but not in the mountain when your to the bar all day long!
