buddalun: Yes, I've got maybe 5k miles on them. Played around a bit with settings, tire PSI, finally arrived at F: 13/8, R: 13/8. (Compression/Rebound) This seems to be the best compromise for my region, especially the rather large uneven concrete heaves that I have to drive on to/from my house, and on my short (3.5 mile) commute.
The "slap", as I call it, is the harsh feel when the tires encounter a 2"-3" concrete lip between slabs. The stiff sidewall just can't compress as much as the taller sidewall and lower weight rating of our Avalon, and the various other cars I've owned. If I dial in softer compression, I think I'm at risk of too much dive/squat.
I hope that makes sense.
