My tire psi for my EV is set for 36 psi but most dealerships and people keep them at 40 psi. Would this have anything to do with gas mileage and efficiency?
I would think that inflating your tires more would be more efficient but also cause more wear because there’s greater forces on the rubber. But too little inflation would cause them to hit every rock and bang it up more.

If you live in a colder climate and have someone else fill them up, they probably put them to 40 to give you some buffer room. For every 10 or so degrees the air temp drops, you’ll naturally lose a pound of pressure.
Minnesotan here. I always slightly over inflate mine in the winter so I’m not messing around with them every day.
