I keep mine around 36-37 for the OEM wheels and winter tires. My OEM tires were overinflated to the high 40s and low 50s upon delivery in January 2018, I didn't really notice until it snowed a few days later and the traction was bad. After adjusting the tire pressure, the traction was much better. I made sure to call my salesperson to advise them, and they relayed it to their service guys.
