Actually, 38psi is factory recommended.

 

37psi are the recommended pressures for my MY18.

 

36psi recommended for mine, I prefer 38psi.

 

I just checked. 37 as well for the MY’16, but as Dave says, 38 is a better choice. It feels more stable through a high speed sweeping turn.

 

also remember your caddy probably didnt have huge rims and low profile tires, this makes a big difference is firm/soft ride.

 

Nothing quite like getting your dream car and then immediately putting it in the garage to sit while we have two straight weeks of single digit temps with negative wind chill and snow/ice! No relief in sight! Since delivery last Thursday I've taken two short drives, less than 30 minutes. Come on Spring!

 

get in the car and drive south until you hit the sun and 70 degrees
