THe sharpe edge on  a tire like this can be caused
by many things.  In the Syncro, my problem was the
overly aggresive VC.  This locked it in 4 Wheel drive.
The net resault is the  tires have to give way to the
drive train and rips the h#$% out off them.   This
IMHO is a nother good reasn for a de-coupler.
