I just put on some new 18x9.5 rims with some nitto nt555 275/40 tires. What pressure I should put in them for daily driving? I've got them at 32 psi right now (the same as the pressure I used for the stock tires/rims). Do I need to change that due to the lower profile? What about at the drag strip? Thanks!

I would run it up near 38 psi or so. Maybe even a little higher. I would check what the tires say to pump them to.

The tire will only tell you the maximum psi of the tire.
I would recommend 35-37.
Drag strip, not sure, trial and error, but definitely lower that daily driving I would think.

I have 255/45/18 9" fronts and 285/40/18 10" rears with Nitto 555's
and kept the 32 psi for daily driving and no issues. Drag strip is trial and error and I would play around with an additional 5-6 lbs....
