The new, lower profile tires seem to like a little less pressure than the earlier models did. The new ones are a little more "squirmy" at the higher pressures, from what I have heard...and the increase above the OEM recommended pressure is no longer needed to counteract the tire portion of the body roll with the more rigid tires.
:2thumbs: I ran 18 psi front on my 2008. My STS was delivered with 13 psi. I pumped it up to 18 and didn't like the ride or handling. I settled on 16 as good for me. I doubt tire pressure is the OP's problem, but I'd try 15-16 psi and see if you like it better,
