I would make sure your alignment is correct. My MS3 came from the factory with not enough toe-in. it was very skittish especially at highway speeds- you really had to hold the wheel with both hands. When I corrected for 1/2 degree toe-in it is now stable at speed. Obviously an incorrect alignment will increase tire wear. How I did the alignment is either somewhere on Talk Morgan or on Facebook- Morgan Super 3 Chapter thread.
