Correct pressure for best traction is dependent on weight of vehicle and load carrying capacity of the tire - a LX weighs less than an Si by nearly 200 pounds. A stock wheel for a 2016 LX is 215x55x16. Op is running 235/40R18 at 32 psi. In my experience if the door sticker says 32 psi for the OEM tire then several psi less is likely to provide a better tire patch contact and thus higher traction. Higher pressure usually reduces footprint and can greatly reduce traction, grip, and accelerate wear in the center of the tire. Only advantage is better mpg.Bring up your cold operating psi to 35 front, 34 rear. Maybe you'll see a difference(?).
