[QUOTE="Allen_C, post: 1182176, member: 86444"] I run 1up preload, Soft -2 when on slab or rough city streets, Std 0 on wide sweepers and Hard +2 on tight curves. When my 135# wife is on the back, we run 2up or 2up with luggage if appropriate. Tire pressure is 39-40 front and 42-43 rear. These settings provide smooth rides on slab and great control of suspension travel on curves. The ride is similar to my '08AE with 17k miles but my ES no longer bottoms out on small bumps when we are 2up, unlike what the Gen2 did. I'm on my second front tire and third rear now that I have 16.5k miles. They have all been BT-023s. The first set were run at 36F and 39R psi for the first 4k miles and the front started to scallop and caused a head shake. I increased the pressures to 39/42 and the headshake reduced through the full 9.2k miles the tire lasted. My current front has been set at 39-40 psi since the beginning and has not scalloped. I've had no headshake during its 7.3k miles and it appears to be about half-way through its life. I suggest playing around with the + and - on the Soft and Hard settings to see if it helps with the smoothness and stability you seek when running at the higher pressures. Good luck! [/QUOTE]
