I'm coming from a 2002 ES 300 and the ride on the CT seems a lot more bumpy. MY tire pressure is at 38psi. I can try lowering that a little but I'm not sure how much it would help.
I was wondering if the dealer can my the suspension less stiff somehow?
Lowering the front tires to 33 psi and 32 psi for the rear tires will improve your ride quality. These psi's are recommended by Lexus and noted on the driver side door frame. Increasing the psi from these psi's will improve your mpg , but will make the CT ride harder.The roads were smooter when I took it for a test drive so I didn't really notice.
However, I did lower the psi to 35 and it does feel a bit better. I probably get used to it too.
