Another thing to watch is how wide the tread on the tire is VS the width of the wheel rim where the tire bead seats. I try not to exceed more then one inch wider tread VS rim width. Going with a larger difference AND running at higher inflation will give you the 'over-inflation' wear pattern. Conversely, running a tread width narrower then the rim width will give an 'under inflation' wear pattern even at high inflation pressures, particularly on a town driven vehicle. Other then that, I can't add to what has already been said.
