What’s your ideal Tire pressure?

When I took delivery of my car, the tire pressure was set to 33 PSI. Later, I read on Reddit that 36 PSI is the optimal setting, so I tried it. The ride felt softer, and bumps were less noticeable. However, the car kept warning me about tire pressure. So, I inflated the tires to the recommended 42 PSI. Now, I feel more bumps, but on my regular route—which used to consume 4% of the battery (M3RWD Standard)—it only uses 2%, which I consider a win.
