Got the tires today, added on the "replace these suckers for free no matter what happened to them" warranty. So total ran $580 out the door, free rotations and balance for life. Not bad. BTW, the "local" shop turns out to be Tire Discounters. Asked about "siping" ... guy was real honest, says don't even think about it on these tires, they have factory siping on 'em. They do like to sipe most others though.
Ride is much smoother, feels like the tires are under inflated they are so smooth. But I checked and they are at about 33 PSI, so if I go down to 30, they will be too soft maybe. Quiet, handles well, smooth. Good and good so far!
