37 in back. Is this right? thanks!

Check the inside of your gas filler flap. Use that as a starting point, then adjust (up) as you desire. As you increase pressure you will get better performance, but a harsher ride.

Check inflation in the morning before any driving.

As the weather warms from spring to summer you will probably have to bleed a little air. Converseley as it cools in the fall, you will have to add some.
