I ran Good Year F1 Gs-D2's, staggered (225/40/18 - 255/35/18) for 52k miles. The rears were pretty much done, BUT the fronts still looked good except for some bad feathering on the inside due to bad CAB's. I just put another set of F1 Gs-D3 (hard to find) staggered hoping to get another 50k. They were excellent tires on dry BUT were outstanding on wet roads.
